Method Detail

getResult

public AbstractCompiledPermissions.Result getResult(Path absPath)
                                             throws javax.jcr.RepositoryException

Parameters:

absPath -

Returns:

the Result for the give absPath.

Throws:

javax.jcr.RepositoryException

buildResult

protected abstract AbstractCompiledPermissions.Result buildResult(Path absPath)
                                                           throws javax.jcr.RepositoryException

Parameters:

absPath -

Returns:

Throws:

javax.jcr.RepositoryException

clearCache

protected void clearCache()

close

public void close()

Description copied from interface: CompiledPermissions

Indicate to this CompiledPermissions object that it is not used any more.

Specified by:

close in interface CompiledPermissions

See Also:

CompiledPermissions.close()

grants

public boolean grants(Path absPath,
                      int permissions)
               throws javax.jcr.RepositoryException

Description copied from interface: CompiledPermissions

Returns true if the specified permissions are granted on the item identified by the given path.

Specified by:

grants in interface CompiledPermissions

Parameters:

absPath - Absolute path pointing to an item. If the item does not exist yet (asking for 'add-node' and 'set-property' permission), it's direct ancestor must exist.

permissions - A combination of one or more of permission constants defined by Permission encoded as a bitmask value

Returns:

true if the specified permissions are granted, false otherwise.

Throws:

javax.jcr.RepositoryException - if an error occurs.

See Also:

CompiledPermissions.grants(Path, int)

getPrivileges

public int getPrivileges(Path absPath)
                  throws javax.jcr.RepositoryException

Description copied from interface: CompiledPermissions

Returns the Privileges granted by the underlying policy if the given absPath denotes an existing Node, otherwise it returns zero.

Specified by:

getPrivileges in interface CompiledPermissions

Returns:

the granted privileges at absPath or zero if the path does not denote an existing Node.

Throws:

javax.jcr.RepositoryException - if an error occurs

See Also:

CompiledPermissions.getPrivileges(Path)

canReadAll

public boolean canReadAll()
                   throws javax.jcr.RepositoryException

Description copied from interface: CompiledPermissions

Returns true if READ permission is granted everywhere. This method acts as shortcut for CompiledPermissions.grants(Path, int) where permissions is Permission.READ and allows to shorten the evaluation time given the fact that a check for READ permission is considered to be the most frequent test.

Specified by:

canReadAll in interface CompiledPermissions

Returns:

true if the READ permission is granted everywhere.

Throws:

javax.jcr.RepositoryException - if an error occurs

CompiledPermissions.canReadAll()
