  • Method Details

    • getBranch

      CDOBranch getBranch()
      Description copied from interface: CDOBranchPoint
      Returns the branch of this branch point, or null if this branch point is the base of the main branch.
      Specified by:
      getBranch in interface CDOBranchPoint
      Specified by:
      getBranch in interface CDOBranchProvider
      Returns:
      The branch at which the lock changes took place, same as getView().getBranch().

    • getTimeStamp

      long getTimeStamp()
      Description copied from interface: CDOBranchPoint
      Returns the time stamp of this branch point, or the fixed special time stamp unspecified if this branch point marks the head of a branch.
      Specified by:
      getTimeStamp in interface CDOBranchPoint
      Specified by:
      getTimeStamp in interface CDOTimeProvider
      Returns:
      The repository time at which the lock changes took place. This is only an informal indication; no formal relation (e.g. an ordering) with commit time stamps is guaranteed.

    • getLockOwner

      CDOLockOwner getLockOwner()
      Returns:
      The view, represented as a CDOLockOwner, that authored the lock changes.

    • getLockDeltas

      CDOLockDelta[] getLockDeltas()
      Since:
      4.15

    • getLockStates

      CDOLockState[] getLockStates()
      Returns:
      The new lock states of the objects that were affected by the change

    • getOperations

      Set<CDOLockChangeInfo.Operation> getOperations()
      Since:
      4.15

    • getLockTypes

      Set<org.eclipse.net4j.util.concurrent.IRWLockManager.LockType> getLockTypes()
      Since:
      4.15

    • getAffectedIDs

      Since:
      4.15

    • isInvalidateAll

      boolean isInvalidateAll()
      Returns:
      true if this instance signals that all lock states must be invalidated, false otherwise

    • getOperation

      @Deprecated CDOLockChangeInfo.Operation getOperation()
      Deprecated.
      As of 4.15 use getOperations().
      Returns:
      the type of lock operation that caused the lock changes

    • getLockType

      @Deprecated org.eclipse.net4j.util.concurrent.IRWLockManager.LockType getLockType()
