org.eclipse.emf.cdo.spi.common.lock.AbstractCDOLockState

All Implemented Interfaces:: CDOBranchProvider, CDOIdentifiable, CDOLockState, CDOIDAndBranch, InternalCDOLockState

public abstract class AbstractCDOLockState extends Object implements InternalCDOLockState

Shared implementation for lock states keyed by an object ID, optionally scoped to a branch. It tracks the owners of read, write, and write-option locks and produces lock deltas as ownership changes are applied.
