Field Detail

MARKER

static final java.lang.String MARKER

This is the ID used for Eclipse markers which are based on diagnostics.

Constant Field Values

URI_ATTRIBUTE

static final java.lang.String URI_ATTRIBUTE

This is the name of the marker attribute to hold the String representation of the URI of the object that is the target of the marker.

EcoreUtil.getURI(org.eclipse.emf.ecore.EObject), Constant Field Values

RELATED_URIS_ATTRIBUTE

static final java.lang.String RELATED_URIS_ATTRIBUTE

This is the name of the marker attribute to hold a space separated sequence of encoded Strings where each string is the URI of an object related to the target of the marker. The vale of this attribute should be processed as follows:

  for (String relatedURI : relatedURIs.split(" "))
  {
    URI uri = URI.createURI(URI.decode(relatedURI));
    // ...
  }

Method Detail

validate

boolean validate(EObject eObject,
               DiagnosticChain diagnostics,
               java.util.Map<java.lang.Object,java.lang.Object> context)

Validates the object in the given context, optionally producing diagnostics.

Parameters:

diagnostics - a place to accumulate diagnostics; if it's null, no diagnostics should be produced.

context - a place to cache information, if it's null, no cache is supported.

Returns:

whether the object is valid.
