Returns the specified message.

Specified by:

getMessage in class MessageReceiver

Parameters:

index - the position of the message to be returned

Returns:

the specified message

errorImpl

private Message errorImpl(java.lang.String message,
                          org.eclipse.emf.ecore.EObject cause,
                          org.eclipse.emf.ecore.EStructuralFeature causeFeature,
                          int code)

Receives an error message.

Parameters:

code - a numerical identification of the error

Returns:

the created/stored message

warningImpl

private Message warningImpl(java.lang.String message,
                            org.eclipse.emf.ecore.EObject cause,
                            org.eclipse.emf.ecore.EStructuralFeature causeFeature,
                            int code)

Receives a warning message.

Parameters:

causeFeature - the cause of the feature as an appropriate constant from IvmlPackage.Literals

code - a numerical identification of the warning

Returns:

the created/stored message

error

public void error(java.lang.String message,
                  org.eclipse.emf.ecore.EObject cause,
                  org.eclipse.emf.ecore.EStructuralFeature causeFeature,

Description copied from interface: IMessageReceiver

Receives an error message.

Parameters:

message - the message

cause - the cause (as instance of the EMF grammar model)

causeFeature - the cause of the feature as an appropriate constant from IvmlPackage.Literals

code - a numerical identification of the error

Specified by:

error in class MessageReceiver

Parameters:

diagnostic - the diagnostic to be added

clearMessages

public void clearMessages(ModelInfo<?> info)

Clears all messages registered for info.

Parameters:

info - the information object to clear the messages for

clearMessages

public void clearMessages(java.net.URI uri)

Clears all messages registered for the resource uri.

Parameters:

uri - the URI to clear the messages for

sameURIs

private static boolean sameURIs(java.net.URI uri,
                                org.eclipse.emf.ecore.EObject cause)

Checks whether uri and the URI of cause are the same.

Parameters:
