    @NotThreadSafe
    public class JcrRequestProcessor

extends RequestProcessor

A `RequestProcessor` that processes `Request`s by operating against the JCR `Repository`.

Nested Class Summary
`protected class` | `JcrRequestProcessor.Workspace` An encapsulation of a remote JCR Session, with an ExecutionContext that contains a namespace registry which mirrors the session's registry, and with factories that convert the JCR-specific values, paths, and names into their graph-equivalents.

Constructor Detail

### JcrRequestProcessor

    public JcrRequestProcessor(String sourceName,
                               ExecutionContext context,

                               CachePolicy defaultCachePolicy)

Method Detail

### workspaceFor

    protected JcrRequestProcessor.Workspace workspaceFor(String workspaceName)
                                                  throws RepositoryException

  Obtain the JCR session for the named workspace in the current repository using the credentials given to this processor during instantiation. If no workspace name is supplied, a session for the default workspace is obtained.

  This method caches a single `Session` object for each named (or default) workspace, so multiple calls with the same workspace name will always result in the same `Session` object. These cached Session objects are released only when this processor is `closed`.

  Parameters:
    `workspaceName` - the name of the workspace for which a Session is to be found, or null if a session to the default workspace should be returned
  Returns:
    the Session to the workspace, or null if there was an error
  Throws:
    `NoSuchWorkspaceException` - if the named workspace does not exist
    `RepositoryException` - if there is an error creating a Session

### workspace

    protected JcrRequestProcessor.Workspace workspace()
                                               throws RepositoryException

  Use the first workspace that's available, or if none is available establish one for the default workspace.

  Returns:
    the workspace, or null if there was an error
  Throws:
    `RepositoryException` - if there is an error creating a Session

### workspaceExistsNamed

    protected boolean workspaceExistsNamed(String workspaceName)
                                    throws RepositoryException

  Determine if there is an existing workspace with the supplied name.

  Parameters:
    `workspaceName` - the name of the workspace
  Returns:
    true if the workspace with the supplied name does exist, or false if it does not
  Throws:
    `RepositoryException` - if there is an error working with the session

### commit

    public void commit()
                throws RepositoryException

  Commit all changes to any sessions.

  Throws:
    `RepositoryException` - if there is a problem committing any changes

### rollback

    public void rollback()
                  throws RepositoryException

  Rollback all changes made to any sessions.

  Throws:
    `RepositoryException` - if there is a problem committing any changes
