Member Function Documentation

generateAuxiliaryStruct()

String org.lflang.generator.c.CActionGenerator.generateAuxiliaryStruct ( TypeParameterizedReactor tpr, Action action, Target target, CTypes types, CodeBuilder federatedExtension, boolean userFacing )

static

Generate the struct type definitions for the action of the reactor.

Parameters

tpr	The type-parameterized reactor.
action	The action to generate the struct for
target	The target of the code generation (C, CCpp or Python)
types	The helper object for types related stuff
federatedExtension	The code needed to support federated execution
userFacing	Whether this is user-facing code.

Returns

The auxiliary struct for the port as a string

generateDeclarations()

void org.lflang.generator.c.CActionGenerator.generateDeclarations ( TypeParameterizedReactor tpr, CodeBuilder body, CodeBuilder constructorCode )

static

Generate the declarations of actions in the self struct.

Parameters

tpr	The type-parameterized reactor.
body	The content of the self struct
constructorCode	The constructor code of the reactor

generateInitializers()

String org.lflang.generator.c.CActionGenerator.generateInitializers ( ReactorInstance instance )

static

For each action of the specified reactor instance, generate initialization code for the offset and period fields.

Parameters

instance

The reactor.

generateTokenInitializer()

String org.lflang.generator.c.CActionGenerator.generateTokenInitializer ( String selfStruct, String actionName, String payloadSize )

static

Create a template token initialized to the payload size.

This token is marked to not be freed so that the trigger_t struct always has a template token. At the start of each time step, we need to initialize the is_present field of each action's trigger object to false and free a previously allocated token if appropriate. This code sets up the table that does that.

Parameters

selfStruct	The variable name of the self struct
actionName	The action name
payloadSize	The code that returns the size of the action's payload in C.
