Method Detail

encode

public java.lang.String encode(org.eclipse.emf.ecore.EObject obj,
                               org.eclipse.emf.ecore.EReference ref,
                               INode node)

encodes the given three parameters into a string, so that they can be retrieved from a resource using decode(Resource, String)

Parameters:

obj - the feature holder

ref - the cross reference

node - the node that provided the value for the reference

Returns:

a portable string that may be used as a fragment

appendShortFragment

public void appendShortFragment(org.eclipse.emf.ecore.EObject obj,
                                java.lang.StringBuilder target)

toShortExternalForm

public java.lang.String toShortExternalForm(org.eclipse.emf.ecore.EClass clazz,
                                            org.eclipse.emf.ecore.EReference ref)

decode

public Triple<org.eclipse.emf.ecore.EObject,org.eclipse.emf.ecore.EReference,INode> decode(org.eclipse.emf.ecore.resource.Resource res,
                                                                                           java.lang.String uriFragment)

decodes the uriFragment

Parameters:

res - the resource that contains the feature holder

uriFragment - the fragment that should be decoded

Returns:

the decoded information
