getInternalFrozenNode

public InternalFrozenNode getInternalFrozenNode()
                                         throws RepositoryException

Returns the frozen node of this version

isSame in class ItemImpl

isMoreRecent

public boolean isMoreRecent(VersionImpl v)
                     throws RepositoryException

Always throws a ConstraintViolationException since this node is protected.

Specified by:

merge in interface Node

Overrides:

merge in class NodeImpl

Throws:

ConstraintViolationException

toString

public String toString()

Return a string representation of this version node for diagnostic purposes.

Overrides:

toString in class NodeImpl

Returns:

"version node /path/to/item"
