Field Detail

_javaParseTreeCodeGenerator

protected JavaParseTreeCodeGenerator _javaParseTreeCodeGenerator

The parse tree code generator.

Constructor Detail

Expression

public Expression(Expression actor)

Constructor method for the Expression adapter.

Parameters:

actor - The associated actor.

Method Detail

_generateFireCode

protected java.lang.String _generateFireCode()
                                      throws IllegalActionException

Generate fire code. The method reads in fireBlock from Expression.c, replaces macros with their values and appends the processed code block to the given code buffer.

Overrides:

_generateFireCode in class NamedProgramCodeGeneratorAdapter

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 initialize code. This method reads the initBlock from Expression.c, replaces macros with their values and returns the processed code string.

Overrides:

generateInitializeCode in class NamedProgramCodeGeneratorAdapter

Returns:

The processed code string.

Throws:

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

generatePreinitializeCode

public java.lang.String generatePreinitializeCode()
                                           throws IllegalActionException

Generate preinitialize code. This method reads the preinitBlock from Expression.c, replaces macros with their values and returns the processed code string.

Overrides:

generatePreinitializeCode in class NamedProgramCodeGeneratorAdapter

Returns:

The processed code string.

Throws:

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

getSharedCode

public java.util.Set<java.lang.String> getSharedCode()
                                              throws IllegalActionException

Get shared code. This method reads the sharedBlock from Expression.c, replaces macros with their values and returns the processed code string.

Overrides:

getSharedCode in class NamedProgramCodeGeneratorAdapter

Returns:

A set of strings that are code shared by multiple instances of the same actor.

Throws:

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

generateWrapupCode

public java.lang.String generateWrapupCode()
                                    throws IllegalActionException

Generate wrap up code. This method reads the wrapupBlock from Expression.c, replaces macros with their values and appends the processed code block to the given code buffer.

Overrides:

generateWrapupCode in class NamedProgramCodeGeneratorAdapter

Returns:

The processed code string.

Throws:

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