Constructor Summary

protected

SimpleKit() Constructor for SimpleKit.

Method Summary

ObjectCopyStrategy	getCopyStrategy(Identity oid)
static SimpleKit	getInstance() Obtain the single instance of SimpleKit
LockMap	getLockMap()
LockWaitStrategy	getLockWaitStrategy()
Swizzling	getSwizzlingStrategy()
protected TransactionFactory	getTransactionFactory()
boolean	isEagerInsert(Object obj) Should OTM perform INSERTs for the given object eagerly or during commit?
boolean	isImplicitLockingUsed() Should OTM implicitely lock all objects that are reachable from the explicitely locked object? The updates to the locked objects are automatically stored to the database at the end of transaction.
