Interface InternalBaseline

All Superinterfaces:

InternalVersion, InternalVersionItem

public interface InternalBaseline
extends InternalVersion

This interface defines the internal baseline.

A baseline is the state of a configuration at some point in time, recorded in version storage. A baseline is similar to a normal version except that instead of representing the state of a single node, it represents the state of an entire partial subgraph.

The internal baseline is the version of the internal configuration.

Method Summary

VersionSet	getBaseVersions() Returns the recorded base versions of all versionable nodes in the configuration.
NodeId	getConfigurationId() Returns the id of the nt:configuration node.
NodeId	getConfigurationRootId() Returns the id of the root node of a workspace configuration.

Method Detail

getBaseVersions

VersionSet getBaseVersions()
                           throws RepositoryException

Returns the recorded base versions of all versionable nodes in the configuration.

Returns:

a map of base versions. the map key is the nodeid of the version history.

Throws:

RepositoryException - if an error occurs

getConfigurationId

NodeId getConfigurationId()

Returns the id of the nt:configuration node. this is basically the versionable id of the history.

Returns:

the configuration node id

getConfigurationRootId

NodeId getConfigurationRootId()

Returns the id of the root node of a workspace configuration. this is basically the jcr:root property of the frozen configuration.

Returns:

the configuration root node id
