Class Protocol

java.lang.Object

org.alfresco.repo.virtual.ref.Protocol

All Implemented Interfaces:

Serializable

Direct Known Subclasses:

NodeProtocol, VirtualProtocol

public class Protocol
extends Object
implements Serializable

A Reference model element that defines the type of the referred artefact and the virtualization process that was applied when creating a reference.
Protocols define the semantics of all elements of a reference. Protocol implementations add syntactic processing methods.
The high level semantic functionality of a protocol is implemented with ProtocolMethods.

dispatch

public <R> R dispatch(ProtocolMethod<R> method,
 Reference reference)
               throws ProtocolMethodException

ProtocolMethod double-dispatch/visitor protocol type selector. Subclasses should override this method to select the appropriate type bound method.
This particular implementation calls the default ProtocolMethod.execute(Protocol, Reference) default method implementation.

Parameters:

method -

reference -

Returns:

the value returned by the type bond method

Throws:

ProtocolMethodException

toString

public String toString()

Overrides:

toString in class Object

propagateNodeRefMutations

public Reference propagateNodeRefMutations(NodeRef mutatedNodeRef,
 Reference reference)

Protocol delegate of Reference.propagateNodeRefMutations(NodeRef)

Parameters:

mutatedNodeRef -

reference -

Returns:

a mutated version of the given Reference corresponding to the given mutated node or the given Reference if no mutations are detected
