Description

A linear sequence of nodes along which an event may be transmitted.

Public Member Functions
	VuoCompilerChain (vector< VuoCompilerNode * > nodes, bool lastNodeInLoop)
	Creates a chain consisting of the given list of nodes.

Function *	generateScheduleWorker (Module module, BasicBlock block, Value compositionStateValue, Value contextValue, string triggerIdentifier, int minThreadsNeeded, int maxThreadsNeeded, size_t chainIndex, vector< size_t > upstreamChainIndices)
	Generates code that schedules the worker function for this chain to execute on the global dispatch queue.

vector< VuoCompilerNode * >	getNodes (void)
	Returns the sequence of nodes in this chain.

bool	isLastNodeInLoop (void)
	Returns true if this chain represents a single node that is the last (and only repeated) node in a feedback loop.

Static Public Member Functions
static Value *	generateMakeContext (Module module, BasicBlock block, Value compositionStateValue, Value eventIdValue)
	Generates code to create a context that can be passed to chain worker functions.

static Value *	generateCompositionStateValue (Module module, BasicBlock block, Value *contextValue)
	Generates code that retrieves the composition identifier from the context argument of a chain worker function.

static Value *	generateEventIdValue (Module module, BasicBlock block, Value *contextValue)
	Generates code that retrieves the event ID from the context argument of a chain worker function.

Constructor & Destructor Documentation

VuoCompilerChain::VuoCompilerChain	(	vector< VuoCompilerNode * >	nodes,
		bool	lastNodeInLoop
	)

Creates a chain consisting of the given list of nodes.

Parameters

nodes	A linear sequence of nodes.
lastNodeInLoop	True if this chain represents a single node that is the last (and only repeated) node in a feedback loop.

Value * VuoCompilerChain::generateCompositionStateValue	(	Module *	module,
		BasicBlock *	block,
		Value *	contextValue
	)

static

Generates code that retrieves the composition identifier from the context argument of a chain worker function.

Value * VuoCompilerChain::generateEventIdValue	(	Module *	module,
		BasicBlock *	block,
		Value *	contextValue
	)

static

Generates code that retrieves the event ID from the context argument of a chain worker function.

Value * VuoCompilerChain::generateMakeContext	(	Module *	module,
		BasicBlock *	block,
		Value *	compositionStateValue,
		Value *	eventIdValue
	)

static

Generates code to create a context that can be passed to chain worker functions.

The context contains the composition state and the event ID.

Function * VuoCompilerChain::generateScheduleWorker	(	Module *	module,
		BasicBlock *	block,
		Value *	compositionStateValue,
		Value *	contextValue,
		string	triggerIdentifier,
		int	minThreadsNeeded,
		int	maxThreadsNeeded,
		size_t	chainIndex,
		vector< size_t >	upstreamChainIndices
	)

Generates code that schedules the worker function for this chain to execute on the global dispatch queue.

Returns: The scheduled function. The caller is responsible for filling in the body of this function.

Function * VuoCompilerChain::getFreeContextFunction ( Module * module )

static

Generates code that deallocates the context argument of a chain worker function.

vector< VuoCompilerNode * > VuoCompilerChain::getNodes ( void )

Returns the sequence of nodes in this chain.

bool VuoCompilerChain::isLastNodeInLoop ( void )

Returns true if this chain represents a single node that is the last (and only repeated) node in a feedback loop.
