Method Detail

generateGetCode

java.lang.String generateGetCode(java.lang.String channel,
                                 java.lang.String offset)
                          throws IllegalActionException

Generate the code to get a token from a port.

Parameters:

channel - The channel for which the get code is generated.

offset - The offset in the array representation of the port.

Returns:

The code that gets data from the channel.

Throws:

IllegalActionException - If the director adapter class cannot be found.

generatePutCode

java.lang.String generatePutCode(java.lang.String channel,
                                 java.lang.String offset,
                                 java.lang.String dataToken)
                          throws IllegalActionException

Generate the code to put a token to a port.

Parameters:

channel - The channel for which the send code is generated.

offset - The offset in the array representation of the port.

dataToken - The token to be sent

Returns:

The code that sends the dataToken on the channel.

Throws:

IllegalActionException - If the director adapter class cannot be found.

generatePutLocalInsideCode

java.lang.String generatePutLocalInsideCode(java.lang.String channel,
                                            java.lang.String offset,
                                            java.lang.String dataToken)
                                     throws IllegalActionException

Generate the code to put a token to a port's local inside receivers.

Parameters:

channel - The channel for which the send code is generated.

offset - The offset in the array representation of the port.

dataToken - The token to be sent

Returns:

The code that sends the dataToken on the channel.

Throws:

IllegalActionException - If the director adapter class cannot be found.

generateHasTokenCode

java.lang.String generateHasTokenCode(java.lang.String channel,
                                      java.lang.String offset)
                               throws IllegalActionException

Generates code to check the receiver has a token.

Parameters:

channel - The channel for which the get code is generated.

offset - The offset in the array representation of the port.

Returns:

The code that generates has token from the channel. FIXME: potentially, we could also pass in a boolean that indicates whether the port the channel resides is a multiport, if it is, then only a static variable is needed instead of an array of length 1.

Throws:

IllegalActionException - If code can't be generated.
