Methods

Modifier and Type	Method and Description
void	checkpoint(javax.jcr.Node node) Creates a version checkpoint for the given node if versioning is enabled for that node type.
void	createVersion(javax.jcr.Workspace workspace, Collection<String> paths) Explicitly creates a version for the nodes at each path provided.
void	nodeUpdated(javax.jcr.Node n) Notifies the version manager that the given node was updated so that if automatic versioning is set for that node, a version checkpoint will be made.
void	nodeUpdated(javax.jcr.Session session, String absPath) Notifies the version manager that the node at a given path was updated so that if automatic versioning is set for that node, a version checkpoint will be made.

Method Detail

nodeUpdated

void nodeUpdated(javax.jcr.Session session,
               String absPath)
                 throws javax.jcr.RepositoryException

Notifies the version manager that the node at a given path was updated so that if automatic versioning is set for that node, a version checkpoint will be made. When a node object is available, use of nodeUpdated(javax.jcr.Node) will save the overhead of a redundant node lookup.

Parameters:

session -

absPath - the absolute path to the node that was created or modified

Throws:

javax.jcr.RepositoryException

nodeUpdated

void nodeUpdated(javax.jcr.Node n)
                 throws javax.jcr.RepositoryException

Notifies the version manager that the given node was updated so that if automatic versioning is set for that node, a version checkpoint will be made.

Parameters:

n - the node that was updated

Throws:

javax.jcr.RepositoryException

createVersion

void createVersion(javax.jcr.Workspace workspace,
                 Collection<String> paths)
                   throws javax.jcr.RepositoryException

Explicitly creates a version for the nodes at each path provided.

Parameters:

workspace - the workspace in which the node resides

paths - absolute paths to the nodes within the workspace

Throws:

javax.jcr.RepositoryException

checkpoint

void checkpoint(javax.jcr.Node node)
                throws javax.jcr.RepositoryException

Creates a version checkpoint for the given node if versioning is enabled for that node type. When versioning is enabled this is the equivalent of VersionManager#checkpoint(node.getPath()), except that it is aware of TxSessions and queues these operations accordingly.

Parameters:

node - the node for whom a new version is to be minted

Throws:

javax.jcr.RepositoryException

setTxService

void setTxService(TransactionService txService)

Parameters:

txService - the txService to set
