Constructor Detail

Counter

public Counter(Counter actor)

Construct the Counter helper.

Parameters:

actor - the associated actor

Method Detail

_generateFireCode

protected java.lang.String _generateFireCode()
                                      throws IllegalActionException

Generate fire code. If both the increment and decrement ports are connected, the counter is offset. Otherwise, if either the increment port or decrement port is connected, read in the incrementBlock or decrementBlock from Counter.c respectively. Replace macros with their values and return the processed code block.

Overrides:

_generateFireCode in class CodeGeneratorHelper

Returns:

The generated code.

Throws:

IllegalActionException - If the code stream encounters an error in processing the specified code block(s).
