EO Template for use by "eogenerator" based upon MiscMerge engine.
You may customize this file to modify the templates generated
by this tool.  See the MiscMerge documentation for a description
of the parsing language.  The engine gets passed this file and an
EOEntity to process, so the methods used must be ones that an
EOEntity can respond to.

tool tries to compare the newly generated file with the old file,
adding dates to this file will guarantee the old file gets
overridden by the new file, forcing a recompilation of your EO.$>

<$comment This is how to put in a custom EO superclass.  We also declare
this class as being abstract, since it should never be instantiated.
public abstract class <$GEN_PREFIX$><$classNameWithoutPackage$> extends <$if hasParentEntity$><$javaParentClassName$><$else$>MyEOSuperclass<$endif$>

Some people like to have constant strings defined for each key. For an
attribute named fooBar, this will declare a FOO_BAR_KEY constant string,
which can be used in calls to valueForKey(), addObjectToBothSides..., etc.
A constant of ENTITY_NAME can be used for fetch specs and other methods.
This lets the compiler flag usages of these keys when the names change.
Additionally, it can be handy to have constants defined for the name 
of the database table, the names of all the attribute column names, and fetch

    public static final String ENTITY_NAME = "<$name$>";
<$if externalName$>
    public static final String ENTITY_TABLE_NAME = "<$externalName$>";<$endif$>
<$foreach attribute attributes.@sortedNameArray do$>
    public static final String <$attribute.name.uppercaseUnderbarString$>_KEY = "<$attribute.name$>";<$endforeach$>
<$foreach attribute attributes.@sortedNameArray do$><$if attribute.columnName$>
    public static final String <$attribute.name.uppercaseUnderbarString$>_COLKEY = "<$attribute.columnName$>";<$endif$><$endforeach$>
<$foreach rel classToOneRelationships.@sortedNameArray do$>
    public static final String <$rel.name.uppercaseUnderbarString$>_KEY = "<$rel.name$>";<$endforeach$>

    public static final String <$rel.name.uppercaseUnderbarString$>_KEY = "<$rel.name$>";<$endforeach$>
<$foreach spec javaBeautifiedFetchSpecificationDictionaries.@sortedNameArray do$>
    public static final String <$spec.fetchName.uppercaseUnderbarString$>_SPEC = "<$spec.fetchName$>";<$endforeach$>


These do the same thing, but use mixed case strings instead of all uppercase.
These are commented out by default

    public static final String EntityName = "<$name$>";
<$if externalName$>
    public static final String EntityTableName = "<$externalName$>";<$endif$>
<$foreach attribute attributes.@sortedNameArray do$>
    public static final String <$attribute.name.initialCapitalString$>Key = "<$attribute.name$>";<$endforeach$>
<$foreach attribute attributes.@sortedNameArray do$><$if attribute.columnName$>
    public static final String <$attribute.name.initialCapitalString$>ColKey = "<$attribute.columnName$>";<$endif$><$endforeach$>
<$foreach rel classToOneRelationships.@sortedNameArray do$>
    public static final String <$rel.name.initialCapitalString$>Key = "<$rel.name$>";<$endforeach$>

This section will create a method to create a new instance of this entity.
It is essentially identical to EOUtilies' createAndInsertInstance method.
This won't necessarily work if you are using inheritance. The commented out
method following this one would be generally a better method to use if
you need to deal with inheritance.

$><$if !isAbstractEntity$>
    public static <$classNameWithoutPackage$> newInstance(EOEditingContext context) {
    	EOClassDescription desc = EOClassDescription.classDescriptionForEntityName(ENTITY_NAME);
    	EOEnterpriseObject object = desc.createInstanceWithEditingContext(context, null);
    	return (<$classNameWithoutPackage$>)object;
<$comment Java does not allow static methods of the same name in a subclass
   to return a different type, so for some types of inheritance the above will
   not work.  In these cases, declare the method like this:

    public static <$classNameWithoutPackage$> new<$classNameWithoutPackage$>Instance(EOEditingContext context)

    public <$GEN_PREFIX$><$classNameWithoutPackage$>() {

Add methods to call named fetch specifications, with any qualifier bindings having typed

$><$foreach FetchSpec javaBeautifiedFetchSpecificationDictionaries.@sortedNameArray do$>
    public static NSArray objectsFor<$FetchSpec.niceName$>(EOEditingContext context<$foreach Binding FetchSpec.bindings do2$>, <$Binding.codeType$><$Binding.name$>Binding<$endforeach do2$>) {
        EOFetchSpecification spec = EOFetchSpecification.fetchSpecificationNamed("<$FetchSpec.fetchName$>", "<$name$>");
<$if FetchSpec.bindings.@count > 0$>
        NSMutableDictionary bindings = new NSMutableDictionary();
<$foreach Binding FetchSpec.bindings do2$>
        if (<$Binding.name$>Binding != null)
            bindings.setObjectForKey(<$Binding.name$>Binding, "<$Binding.name$>");<$endforeach do2$>
        spec = spec.fetchSpecificationWithQualifierBindings(bindings);
        return context.objectsWithFetchSpecification(spec);
<$endforeach do$>

<$foreach Attribute classAttributes.@sortedNameArray do$>
    public <$Attribute.javaValueClassName$> <$Attribute.name$>() {
        return (<$Attribute.javaValueClassName$>)storedValueForKey("<$Attribute.name$>");
    public void set<$Attribute.name.initialCapitalString$>(<$Attribute.javaValueClassName$> aValue) {
        takeStoredValueForKey(aValue, "<$Attribute.name$>");


The following code shows an example of using the userInfo dictionary on an attribute to create
additional methods.

This example allows the user to define the key 'abbreviate' to create a method that will turn a
string into a abbreviated version.  This can be really handy in WO components where you may need
to display a text string that could be very long, but need it to always fit in a certain area.
Additional methods could be made to make shorter or longer abbreviated strings.  The code checks
to see if the type of the attribute is a String and if the abbreviated length is at least greater
than 3 characters, before it will create the method.

<$if Attribute.javaValueClassName eq 'String' and Attribute.userInfo.abbreviate gt 3$>
    public String abbreviated<$Attribute.name.initialCapitalString$>() {
        String value = <$Attribute.name$>();
        if ( value != null && value.length() > <$Attribute.userInfo.abbreviate$> )
            value = value.substring(0,<$Attribute.userInfo.abbreviate$> - 3) + "...";
        return value;

This is just one example of data manipulation that eogenerator can do.  You could have methods that
uppercase values, strip blanks, encrypt the text, etc. all determined by entries in the userInfo
dictionary.  See below for a To-Many relationship example.

<$endforeach do$>

<$foreach ToOneRelationship classToOneRelationships.@sortedNameArray do$>
    public <$ToOneRelationship.destinationEntity.referenceJavaClassName$> <$ToOneRelationship.name$>() {
        return (<$ToOneRelationship.destinationEntity.referenceJavaClassName$>)storedValueForKey("<$ToOneRelationship.name$>");
    public void set<$ToOneRelationship.name.initialCapitalString$>(<$ToOneRelationship.destinationEntity.referenceJavaClassName$> aValue) {
        takeStoredValueForKey(aValue, "<$ToOneRelationship.name$>");

The following method is better than using addObjectToBothSidesOfRelationshipWithKey directly
because you will get compile time type checking instead of runtime checking (plus you don't
risk typos in contstant strings of key names).
    public void set<$ToOneRelationship.name.initialCapitalString$>Relationship(<$ToOneRelationship.destinationEntity.referenceJavaClassName$> value) {
        if (value == null) {
            <$ToOneRelationship.destinationEntity.referenceJavaClassName$> object = <$ToOneRelationship.name$>();
            if (object != null)
                removeObjectFromBothSidesOfRelationshipWithKey(object, "<$ToOneRelationship.name$>");
        else {
            addObjectToBothSidesOfRelationshipWithKey(value, "<$ToOneRelationship.name$>");
<$endforeach do$>

<$foreach ToManyRelationship classToManyRelationships.@sortedNameArray tomanyrels$>
    public NSArray <$ToManyRelationship.name$>() {
        return (NSArray)storedValueForKey("<$ToManyRelationship.name$>");
    public void set<$ToManyRelationship.name.initialCapitalString$>(NSMutableArray aValue) {
        takeStoredValueForKey(aValue, "<$ToManyRelationship.name$>");
    public void addTo<$ToManyRelationship.name.initialCapitalString$>(<$ToManyRelationship.destinationEntity.referenceJavaClassName$> object) {
        NSMutableArray array = (NSMutableArray)<$ToManyRelationship.name$>();
    public void removeFrom<$ToManyRelationship.name.initialCapitalString$>(<$ToManyRelationship.destinationEntity.referenceJavaClassName$> object) {
        NSMutableArray array = (NSMutableArray)<$ToManyRelationship.name$>();

The following adds typed methods to add or remove an object from a to-many relationship.
This is better than using addObjectToBothSidesOfRelationshipWithKey directly because
you will get compile time type checking instead of runtime checking, and you avoid the
possibility of making a typo in the key name.
    public void addTo<$ToManyRelationship.name.initialCapitalString$>Relationship(<$ToManyRelationship.destinationEntity.referenceJavaClassName$> object) {
        addObjectToBothSidesOfRelationshipWithKey(object, "<$ToManyRelationship.name$>");
    public void removeFrom<$ToManyRelationship.name.initialCapitalString$>Relationship(<$ToManyRelationship.destinationEntity.referenceJavaClassName$> object) {
        removeObjectFromBothSidesOfRelationshipWithKey(object, "<$ToManyRelationship.name$>");

The following adds typed methods to create, and delete objects from a to-many relationship.
The main difference in the delete mechanism, versus the removeFrom... method above is that
this delete method will remove the object from the editing context if it is we do not own
its destination.  The user can override these methods in the subclass to provide additional
functionality on these methods.
    public <$ToManyRelationship.destinationEntity.referenceJavaClassName$> create<$ToManyRelationship.name.initialCapitalString$>Relationship() {
	EOClassDescription eoClassDesc = EOClassDescription.classDescriptionForEntityName("<$ToManyRelationship.destinationEntity.name$>");
	EOEnterpriseObject eoObject = eoClassDesc.createInstanceWithEditingContext(editingContext(), null);
	addObjectToBothSidesOfRelationshipWithKey(eoObject, "<$ToManyRelationship.name$>");
	return (<$ToManyRelationship.destinationEntity.referenceJavaClassName$>)eoObject;
    public void delete<$ToManyRelationship.name.initialCapitalString$>Relationship(<$ToManyRelationship.destinationEntity.referenceJavaClassName$> object) {
        removeObjectFromBothSidesOfRelationshipWithKey(object, "<$ToManyRelationship.name$>");<$
if !ToManyRelationship.ownsDestination$>
    public void deleteAll<$ToManyRelationship.name.initialCapitalString$>Relationships() {
	Enumeration objects = new NSArray(<$ToManyRelationship.name$>()).objectEnumerator();
	while ( objects.hasMoreElements() )


The following code is an example of something fancier that can be done than just making creating
the default accessor methods.

A common task in many EOs is to have methods that will return sorted arrays of the to-many
relationships.  While it is generally pretty easy to create these methods, it can become tedious
if you have many relationships that need ordering.  This example provides a way to make generating
those methods easier.

It works by using the userInfo dictionary on an EORelationship.  You can put key-value pairs in
that dictionary that can then be accessed by eogenerator to conditionally compile information.
In the example below, the code looks to see if there is a key named 'sortMethods' defined in
the userInfo dictionary.  If there is, then it presumes that the value will be an array of 
dictionaries that define the sort methods. Each dictionary corresponds to one sort method,
so that you can create multiple methods on a single relationship. This dictionary has one
optional element, a key named 'by' and one required element, a key named 'ordering'. The 'by'
key allows you to specify a extension to be tacked onto the method name. Because you can
create multiple methods for sorting, this is needed to insure you don't have a name conflict.
Note: The code doesn't check for conflicts, it just allows a way out.  The 'ordering' key takes
an array of dictionaries itself.  These dictionaries just has one required element, a 'key' element
and an optional 'sel' element.  The 'key' element should have the name of an attribute to sort
on, while the 'sel' element is just the name of a EOSortOrdering selector, just the part after
the 'EOSortOrdering.Compare' portion for simplicity. If no 'sel' value is given, then the code
just uses Ascending.

So say we have this example userInfo entry for 'sortMethods' on an 'employees' reletionship:

  ({ by = NameAndDOB; ordering = ({key = name; sel = Ascending}, {key = dob; sel = Descending}); },
   { ordering = ({key = name}) };)

We end up with two methods:

   public NSArray orderedEmployeesByNameAndDOB() // Ordered by ascending name and descending dob
   public NSArray orderedEmployees()		 // Ordered by ascending name

<$foreach SortMethod ToManyRelationship.userInfo.sortMethods sortmethodloop$><$
  if SortMethod.ordering.@count gt 0$><$
    if SortMethod.by ne ''$><$setmerge SortMethodBy = "By<$SortMethod.by$>"$><$endif$>

    // Store the sort ordering in a private variable so that it won't take so long to execute the method
    // especially useful if the sort method gets called a lot.
    private static NSArray _orderingsFor<$ToManyRelationship.name.initialCapitalString$><$SortMethodBy$>;
    public NSArray ordered<$ToManyRelationship.name.initialCapitalString$><$SortMethodBy$>() {
        NSArray objects = <$ToManyRelationship.name$>();
        if ( objects.count() > 1 ) {
            if ( _orderingsFor<$ToManyRelationship.name.initialCapitalString$><$SortMethodBy$> == null )
                _orderingsFor<$ToManyRelationship.name.initialCapitalString$><$SortMethodBy$> = new NSArray(
		    new Object[] {<$foreach Ordering SortMethod.ordering orderLoop$><$if OrderingIndex gt 0$>,<$endif$>
                    	EOSortOrdering.sortOrderingWithKey("<$Ordering.key$>", EOSortOrdering.Compare<$if Ordering.sel$><$Ordering.sel$><$else$>Ascending<$endif$>)<$endforeach orderLoop$>

            objects = EOSortOrdering.sortedArrayUsingKeyOrderArray(objects, _orderingsFor<$ToManyRelationship.name.initialCapitalString$><$SortMethodBy$>);
        return objects;
endforeach sortmethodloop$>

This may seem kind of complex and more effort than its worth, but a great many repetitive
coding tasks can be accomplished by eogenerator in this same way.  You could have userInfo
entries for attributes to do case conversion, do data conversion from one type to another
(like T/F to boolean true/false), or create abbreviated strings of very long text. You could
have to-many entries to setup filtering for some defined value(s) you provide.  You could
even stick something in EOEntity's userInfo itself to setup some complex validation checking.

We encourage you to explore the possibilities and if you find you've created some addition that is
really useful, generic enough to be used by others, and you'd like to see included as an
example here, your more than welcome to donate your ideas.
