finalizeReactions()

void org.lflang.generator.python.PythonDelayBodyGenerator.finalizeReactions	(	Reaction	delayReaction,
		Reaction	forwardReaction )

Used to optionally apply additional transformations to the generated reactions.

Implements org.lflang.generator.DelayBodyGenerator.

generateAfterDelaysWithVariableWidth()

boolean org.lflang.generator.c.CDelayBodyGenerator.generateAfterDelaysWithVariableWidth ( )

inherited

Indicates whether delay banks generated from after delays should have a variable length width.

If this is true, any delay reactors that are inserted for after delays on multiport connections will have an unspecified variable length width. The code generator is then responsible for inferring the correct width of the delay bank, which is only possible if the precise connection width is known at compile time.

If this is false, the width specification of the generated bank will list all the ports listed on the right side of the connection. This gives the code generator the information needed to infer the correct width at runtime.

Implements org.lflang.generator.DelayBodyGenerator.

generateDelayBody()

String org.lflang.generator.python.PythonDelayBodyGenerator.generateDelayBody	(	Action	action,
		VarRef	port )

Generate code for the body of a reaction that takes an input and schedules an action with the value of that input.

Parameters

action	The action to schedule
port	The port to read from

Reimplemented from org.lflang.generator.c.CDelayBodyGenerator.

generateDelayGeneric()

String org.lflang.generator.c.CDelayBodyGenerator.generateDelayGeneric ( )

inherited

Generate code for the generic type to be used in the class definition of a generated delay reactor.

Implements org.lflang.generator.DelayBodyGenerator.

generateForwardBody()

String org.lflang.generator.python.PythonDelayBodyGenerator.generateForwardBody	(	Action	action,
		VarRef	port )

Generate code for the body of a reaction that is triggered by the given action and writes its value to the given port.

This realizes the receiving end of a logical delay specified with the 'after' keyword.

Parameters

action	The action that triggers the reaction
port	The port to write to.

Reimplemented from org.lflang.generator.c.CDelayBodyGenerator.
