Constructor Detail

TransformationEvaluator

public TransformationEvaluator(PtalonActor actor)

Construct transformation evaluator.

Parameters:

actor - the Ptalon actor

Method Detail

enterTransformation

public void enterTransformation(boolean incremental)
                         throws PtalonRuntimeException

Enter the transformation.

Overrides:

enterTransformation in class AbstractPtalonEvaluator

Parameters:

incremental - True if this is an incremental transformation.

Throws:

PtalonRuntimeException - Not thrown in this baseclass.

exitTransformation

public void exitTransformation()
                        throws PtalonRuntimeException

Exit the transformation.

Overrides:

exitTransformation in class AbstractPtalonEvaluator

Throws:

PtalonRuntimeException - Not thrown in this baseclass.

negateObject

public void negateObject(java.lang.String name)
                  throws PtalonRuntimeException

Negate an object. A negated object is a NamedObj with a NegationAttribute.

Overrides:

negateObject in class AbstractPtalonEvaluator

Parameters:

name - The name of the NamedObj to be negated.

Throws:

PtalonRuntimeException - If we are in a transformation or if the object has already been negated.

optionalObject

public void optionalObject(java.lang.String name)
                    throws PtalonRuntimeException

Mark a NamedObj as optional. An optional object is a NamedObj with an OptionAttribute.

Overrides:

optionalObject in class AbstractPtalonEvaluator

Parameters:

name - The name of the NamedObj to be marked optional.

Throws:

PtalonRuntimeException - If we are in a transformation or if the object has already been marked optional

preserveObject

public void preserveObject(java.lang.String name)
                    throws PtalonRuntimeException

Preserve an object. A preserved object is a NamedObj with an OptionAttribute.

Overrides:

preserveObject in class AbstractPtalonEvaluator

Parameters:

name - The name of the NamedObj to be preserved

Throws:

PtalonRuntimeException - If we are in a transformation or if the object has already been preserved.

removeObject

public void removeObject(java.lang.String name)
                  throws PtalonRuntimeException

Remove an object.

Overrides:

removeObject in class AbstractPtalonEvaluator

Parameters:

name - The name of the NamedObj to be removed.

Throws:

PtalonRuntimeException - If we are in a transformation or if the object has already been marked as removed.

startAtTop

public void startAtTop()

Prepare the compiler to start at the outermost scope of the Ptalon program during run time.

Overrides:

startAtTop in class PtalonEvaluator

_processAttributes

protected void _processAttributes(NamedObj object)
                           throws PtalonRuntimeException

Process an attribute.

Overrides:

_processAttributes in class AbstractPtalonEvaluator

Parameters:

object - The NamedObj to be processed.

Throws:

PtalonRuntimeException - If thrown while processing the attribute.

_getObject

private NamedObj _getObject(java.lang.String name)
                     throws PtalonScopeException,
                            PtalonRuntimeException

Throws:

PtalonScopeException

PtalonRuntimeException

_removeAttributes

private void _removeAttributes(NamedObj object,
                               java.lang.Class<?>[] attributeClasses)
                        throws IllegalActionException,
                               NameDuplicationException

Throws:

IllegalActionException

NameDuplicationException
