er.extensions.eof

Class ERXCopyable.DefaultImplementation

java.lang.Object

er.extensions.eof.ERXCopyable.DefaultImplementation

Enclosing interface:

ERXCopyable<T extends ERXCopyable<T>>

public static class ERXCopyable.DefaultImplementation
extends Object

This class provides a default implementation of ERXCopyable that handles the most common situations encountered copying EOEnterpriseObject s.

Notes

• Debugging information can be turned on with the DEBUG level of the log4j logger

   er.extensions.eof.ERXCopyable}.
   

• If you implement your own deep copy of relationships you should register the new object before copying its relationships to so that circular relationships will be copied correctly. For example:

  
   EOGlobalID globalID = editingContext().globalIDForObject(this);
   copiedObjects.setObjectForKey(copy, globalID);

Method Detail

copy

public static <T extends ERXCopyable<T>> T copy(NSMutableDictionary<com.webobjects.eocontrol.EOGlobalID,ERXCopyable<?>> copiedObjects,
                                                T source)

Returns a copy of this object. The actual copy mechanism, Reference, Deep, etc. is up to the object being copied. If a copy already exists in the copiedObjects dictionary, then that existing copy is returned instead of making a new copy. This allows complex graphs of objects, including those with cycles, to be copied without producing duplicate objects.

Type Parameters:

T - the Type of the source

Parameters:

copiedObjects - the copied objects keyed on the EOGlobalID of the object the copy was made from.

source - the ERXCopyable to copy

Returns:

a copy of this object

duplicate

public static <T extends ERXCopyable<T>> T duplicate(NSMutableDictionary<com.webobjects.eocontrol.EOGlobalID,ERXCopyable<?>> copiedObjects,
                                                     T source)

Returns a deep copy of this object.

Type Parameters:

T - the Type of the source

Parameters:

copiedObjects - the copied objects keyed on the EOGlobalID of the object the copy was made from.

source -

Returns:

a deep copy of this object
