Method Detail

clearDeferredChanges

void clearDeferredChanges()

INTERNAL: clear any changes that have been deferred to instantiation. Indirect collections with change tracking avoid instantiation on add/remove.

hasDeferredChanges

boolean hasDeferredChanges()

INTERNAL: Return if the collection has any changes that have been deferred to instantiation. Indirect collections with change tracking avoid instantiation on add/remove.

getAddedElements

java.util.Collection getAddedElements()

INTERNAL: Return if the collection has any elements added that have been deferred to instantiation. Indirect collections with change tracking avoid instantiation on add/remove.

getRemovedElements

java.util.Collection getRemovedElements()

INTERNAL: Return if the collection has any elements removed that have been deferred to instantiation. Indirect collections with change tracking avoid instantiation on add/remove.

getDelegateObject

java.lang.Object getDelegateObject()

INTERNAL: Return the real collection object. This will force instantiation.

setUseLazyInstantiation

void setUseLazyInstantiation(boolean useLazyInstantiation)

INTERNAL Set whether this collection should attempt do deal with adds and removes without retrieving the collection from the dB
