Class SphinxManagedModelFileContentHandlerImpl

java.lang.Object

org.eclipse.emf.ecore.resource.impl.ContentHandlerImpl

org.eclipse.sphinx.emf.resource.SphinxManagedModelFileContentHandlerImpl

All Implemented Interfaces:

org.eclipse.emf.ecore.resource.ContentHandler

public class SphinxManagedModelFileContentHandlerImpl
extends org.eclipse.emf.ecore.resource.impl.ContentHandlerImpl

A performance-optimized handler for describing the contents of Sphinx-managed model files referenced by a given URI.

Delegates to the performance-optimized content type id detection support provided by ExtendedPlatform in case that provided URI refers to a Sphinx-managed model file inside the workspace and only the content type id but no other content description properties are requested. In all other cases, i.e., when the provided URI references some file that is apparently not managed by Sphinx or when additional content description properties are explicitly requested, this class delegates to its super implementation. The latter retrieves and returns an indeterminate best guess content description which may subsequently be overridden by another content handler (e.g., PlatformContentHandlerImpl) with some more appropriate content description (see org.eclipse.emf.ecore.resource.impl.URIHandlerImpl#contentDescription(URI, Map) for details).
