Method Summary

Modifier and Type	Method and Description
VersionHistory	getContainingHistory() Returns the VersionHistory that contains this Version.
java.util.Calendar	getCreated() Returns the date this version was created.
Node	getFrozenNode() Returns the frozen node of this version.
Version	getLinearPredecessor() Assuming that this Version object was acquired through a Workspace W and is within the VersionHistory H, this method returns the predecessor of this version along the same line of descent as is returned by H.getAllLinearVersions() where H was also acquired through W.
Version	getLinearSuccessor() Assuming that this Version object was acquired through a Workspace W and is within the VersionHistory H, this method returns the successor of this version along the same line of descent as is returned by H.getAllLinearVersions() where H was also acquired through W.
Version[]	getPredecessors() In both simple and full versioning repositories, this method returns the predecessor versions of this version.
Version[]	getSuccessors() Returns the successor versions of this version.

Method Detail

getContainingHistory

VersionHistory getContainingHistory()
                             throws RepositoryException

Returns the VersionHistory that contains this Version.

Returns:

the VersionHistory that contains this Version.

Throws:

RepositoryException - if an error occurs.

getCreated

java.util.Calendar getCreated()
                       throws RepositoryException

Returns the date this version was created. This corresponds to the value of the jcr:created property in the nt:version node that represents this version.

Returns:

a Calendar object

Throws:

RepositoryException - if an error occurs.

getLinearSuccessor

Version getLinearSuccessor()
                    throws RepositoryException

Assuming that this Version object was acquired through a Workspace W and is within the VersionHistory H, this method returns the successor of this version along the same line of descent as is returned by H.getAllLinearVersions() where H was also acquired through W.

Note that under simple versioning the behavior of this method is equivalent to getting the unique successor (if any) of this version.

Returns:

a Version or null if no linear successor exists.

Throws:

RepositoryException - if an error occurs.

See Also:

VersionHistory.getAllLinearVersions()

getSuccessors

Version[] getSuccessors()
                 throws RepositoryException

Returns the successor versions of this version. This corresponds to returning all the nt:version nodes referenced by the jcr:successors multi-value property in the nt:version node that represents this version.

In a simple versioning repository this method

Returns:

a Version array.

Throws:

RepositoryException - if an error occurs.

getLinearPredecessor

Version getLinearPredecessor()
                      throws RepositoryException

Assuming that this Version object was acquired through a Workspace W and is within the VersionHistory H, this method returns the predecessor of this version along the same line of descent as is returned by H.getAllLinearVersions() where H was also acquired through W.

Note that under simple versioning the behavior of this method is equivalent to getting the unique predecessor (if any) of this version.

Returns:

a Version or null if no linear predecessor exists.

Throws:

RepositoryException - if an error occurs.

See Also:

VersionHistory.getAllLinearVersions()

getPredecessors

Version[] getPredecessors()
                   throws RepositoryException

In both simple and full versioning repositories, this method returns the predecessor versions of this version. This corresponds to returning all the nt:version nodes whose jcr:successors property includes a reference to the nt:version node that represents this version.

Returns:

a Version array.

Throws:

RepositoryException - if an error occurs.

getFrozenNode

Node getFrozenNode()
            throws RepositoryException

Returns the frozen node of this version.

Returns:

a Node object

Throws:

RepositoryException - if an error occurs.
