DataConstraint

public DataConstraint(ScuflModel model,
                      java.lang.String source_name,
                      java.lang.String sink_name)
               throws DataConstraintCreationException,
                      UnknownPortException,
                      UnknownProcessorException,
                      MalformedNameException

Create a new data constraint from two name strings of the form [PROCESSOR]:[PORT] for source and sink. These must exist within the model specified.

Throws:

MalformedNameException - if the name supplied is not in the correct format

DataConstraintCreationException - if the ports are found but are incorrectly typed

UnknownPortException - if the processor is found but doesn't contain the named port

UnknownProcessorException - if the model doesn't contain the particular processor name

DataConstraint

public DataConstraint(ScuflModel model,
                      Port source,
                      Port sink)
               throws DataConstraintCreationException

Create a new data constraint from the source to the sink port. The ports must be instances of OutputPort and InputPort respectively

Throws:

DataConstraintCreationException - if the ports are found but are incorrectly typed
