Constructor Detail

ModelTranslator

public ModelTranslator(E expressionTranslator)

Creates a new model translator.

Parameters:

expressionTranslator - the associated expression translator

Method Detail

select

public static <T extends org.eclipse.emf.ecore.EObject> java.util.List<T> select(java.util.List<? extends org.eclipse.emf.ecore.EObject> objects,
                                                                                 java.lang.Class<T> type)

Selects the given objects by type.

Type Parameters:

T - the actual type of list entries

Parameters:

objects - the objects to be considered

type - the type as selection criterion

Returns:

the selected objects being instance of type

copy

public static <T> java.util.List<T> copy(java.util.List<T> objects)

Copies a set of objects.

Type Parameters:

T - the actual type of list entries

Parameters:

objects - the objects to be copied (may be null)

Returns:

the copied instance (null if object is null)

getExpressionTranslator

protected E getExpressionTranslator()

Returns the associated expression translator.

Returns:

the expression translator

getMessageCount

public int getMessageCount()

Description copied from class: MessageReceiver

Returns the number of messages.

Specified by:

getMessageCount in class MessageReceiver

Returns:

the number of messages

getErrorCount

public int getErrorCount()

Description copied from class: MessageReceiver

Returns the number of errors.

Specified by:

getErrorCount in class MessageReceiver

Returns:

the number of errors

getMessage

public Message getMessage(int index)

Description copied from class: MessageReceiver

Returns the specified message.

Specified by:

getMessage in class MessageReceiver

Parameters:

index - the position of the message to be returned

Returns:

the specified message

error

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

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

warning

public void warning(java.lang.String message,
                    org.eclipse.emf.ecore.EObject cause,
                    org.eclipse.emf.ecore.EStructuralFeature causeFeature,
                    int code)

Description copied from interface: IMessageReceiver

Receives a warning 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 warning

collect

public void collect(IMessage message,
                    org.eclipse.emf.ecore.EObject cause,
                    org.eclipse.emf.ecore.EStructuralFeature causeFeature,
                    int code)

Description copied from interface: IMessageReceiver

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

error

public void error(org.eclipse.emf.ecore.resource.Resource.Diagnostic diagnostic)

Adds a diagnostic error, typically from a standalone parser configuration.

Specified by:

error in class MessageReceiver

Parameters:

diagnostic - the diagnostic to be added

addMessage

public void addMessage(Message msg)

Adds a message.

Specified by:

addMessage in class MessageReceiver

Parameters:

msg - the message to be added
