Constructor Detail

LineWriter

public LineWriter(LineWriter actor)

Construct the LineWriter helper.

Parameters:

actor - the associated actor.

Method Detail

_generateFireCode

protected java.lang.String _generateFireCode()
                                      throws IllegalActionException

Generate fire code. The method reads in writeLine from LineWriter.c, replaces macros with their values and returns the code buffer.

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).

generateInitializeCode

public java.lang.String generateInitializeCode()
                                        throws IllegalActionException

Generate initialization code. This method first checks if "System.out" is the file parameter. If so, it reads from LineWriter.c for the openForStdout block, which is code for opening standard output stream. Then, the method checks the actor's confirmOverwrite and appends parameters, reads the confirmOverwrite, openForAppend, and openForWrite blocks accordingly. Then it replaces macros with their values and returns the resulting code string.

Specified by:

generateInitializeCode in interface ComponentCodeGenerator

Overrides:

generateInitializeCode in class CodeGeneratorHelper

Returns:

The processed code string.

Throws:

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

getHeaderFiles

public java.util.Set getHeaderFiles()
                             throws IllegalActionException

Get the files needed by the code generated for the LineWriter actor.

Specified by:

getHeaderFiles in interface ActorCodeGenerator

Overrides:

getHeaderFiles in class CCodeGeneratorHelper

Returns:

A set of strings that are names of the files needed by the code generated for the LineWriter actor.

Throws:

IllegalActionException - Not Thrown in this subclass.
