public int whenShouldAcquireValueForAll()

Implements org.eclipse.persistence.internal.sequencing.Sequencing.whenShouldAcquireValueForAll.

Doc from org.eclipse.persistence.internal.sequencing.Sequencing.whenShouldAcquireValueForAll.

INTERNAL: Indicates when sequencing value should be acquired for all classes. There are just three possible return values: BEFORE_INSERT, UNDEFINED, AFTER_INSERT. Used as a shortcut to avoid individual checks for each class: shouldAcquireValueAfterInsert(Class cls). Currently UNDEFINED only happens in a case of a SessionBroker: session1 - BEFORE_INSERT, session2 - AFTER_INSERT
