Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method and Description
`CDOBranch`	`getBranch()` Returns the branch of this branch point, or `null` if this branch point is the `base` of the `main branch`.
`CDOLockOwner`	`getLockOwner()`
`CDOLockState[]`	`getLockStates()`
`IRWLockManager.LockType`	`getLockType()`
`CDOLockChangeInfo.Operation`	`getOperation()`
`long`	`getTimeStamp()` 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.
`boolean`	`isInvalidateAll()`

- Method Detail
  - isInvalidateAll
```
boolean isInvalidateAll()
```
    Returns:
    
    true if this instance signals that all lockstates must be invalidated, false otherwise
  - 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
    
    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 timestamps is guaranteed.
  - getLockOwner
```
CDOLockOwner getLockOwner()
```
    Returns:
    
    The view, represented as a CDOLockOwner, that authored the lock changes.
  - getLockStates
```
CDOLockState[] getLockStates()
```
    Returns:
    
    The new lock states of the objects that were affected by the change
  - getOperation
```
CDOLockChangeInfo.Operation getOperation()
```
    Returns:
    
    the type of lock operation that caused the lock changes
  - getLockType
```
IRWLockManager.LockType getLockType()
```
    Returns:
    
    the type of locks that were affected by the lock operation
