Detailed Description

Generate Python code for ports.

Member Function Documentation

generateActionVariableToSendToPythonReaction()

void org.lflang.generator.python.PythonPortGenerator.generateActionVariableToSendToPythonReaction ( List< String > pyObjects, Action action, ReactorDecl decl )

static

Generate code to convert C actions to Python action capsules.

See pythontarget.h for details.

Parameters

pyObjects	A string containing a list of comma-separated expressions that will create the action capsules.
action	The action itself.
decl	The reactor decl that contains the action.

generateAliasTypeDef()

String org.lflang.generator.python.PythonPortGenerator.generateAliasTypeDef ( TypeParameterizedReactor tpr, Port port, boolean isTokenType, String genericPortType )

static

generateInputVariablesToSendToPythonReaction()

void org.lflang.generator.python.PythonPortGenerator.generateInputVariablesToSendToPythonReaction ( List< String > pyObjects, Input input, ReactorDecl decl )

static

Generate into the specified string builder the code to send local variables for input ports to a Python reaction function from the "self" struct.

Parameters

pyObjects	The list of Python object references.
input	The input port.
decl	The reactor declaration.

generateOutputVariablesToSendToPythonReaction()

void org.lflang.generator.python.PythonPortGenerator.generateOutputVariablesToSendToPythonReaction ( List< String > pyObjects, Output output )

static

Generate into the specified string builder the code to send local variables for output ports to a Python reaction function from the "self" struct.

Parameters

pyObjects	The list of Python object references.
output	The output port.

generatePortVariablesToSendToPythonReaction()

String org.lflang.generator.python.PythonPortGenerator.generatePortVariablesToSendToPythonReaction ( List< String > pyObjects, VarRef port, ReactorDecl decl )

static

Generate code to convert C ports to Python ports capsules (.

See also

pythontarget.h).

The port may be an input of the reactor or an output of a contained reactor.

Parameters

pyObjects	A string containing a list of comma-separated expressions that will create the port capsules.
port	The port itself.
decl	The reactor decl that contains the port.

generatePythonListForContainedBank()

String org.lflang.generator.python.PythonPortGenerator.generatePythonListForContainedBank ( String reactorName, Port port, String widthSpec )

static

Generate code that creates a Python list (i.e., []) for contained banks to be passed to Python reactions.

The Python reaction will then subsequently be able to address each individual bank member of the contained bank using an index or an iterator. Each list member will contain the given port (which could be a multiport with a width determined by widthSpec).

This is to accommodate reactions like reaction() -> s.out where s is a bank. In this example, the generated Python function will have the signature reaction_function_0(self, s_out), where s_out is a list of out ports. This will later be turned into the proper s.out format using the Python code generated in generatePythonPortVariableInReaction.

Parameters

reactorName	The name of the bank of reactors (which is the name of the reactor class).
port	The port that should be put in the Python list.
widthSpec	A string that should be -2 for non-multiports and the width expression for multiports.

generatePythonPortVariableInReaction()

String org.lflang.generator.python.PythonPortGenerator.generatePythonPortVariableInReaction ( VarRef port )

static

Generate into the specified string builder (inits) the code to initialize local variable for port so that it can be used in the body of the Python reaction.

Parameters

port	The port to generate code for.

generateVariablesForSendingToContainedReactors()

String org.lflang.generator.python.PythonPortGenerator.generateVariablesForSendingToContainedReactors ( List< String > pyObjects, Instantiation definition, Port port )

static

Generate into the specified string builder the code to pass local variables for sending data to an input of a contained reaction (e.g.

for a deadline violation).

Parameters

pyObjects	The list of Python object references.
definition	AST node defining the reactor within which this occurs
port	Input of the contained reactor.
