Detailed Description

Represent an atomic unit of computation for dependency tracking.

DEP_MicroNode's form a dependency graph that are connected both implicitly and explicitly. The base class maintains the explicit edges while subclasses maintain the implicit edges by overriding the getInputs()/getOutputs() methods.

bool DEP_MicroNode::markVisitPass ( int pass )

void DEP_MicroNode::propagateDirty	(	Visitor	client_visit,
		bool	only_outputs = `false`

Mark this micronode and all its dependents as dirty. The global dirty counter will be incremented once for each call to propagateDirty().

Parameters

client_visit	Called for each micronode that is dirtied
only_outputs	If true, then *this is ommitted from being dirtied

Note: This method is NOT thread-safe with any operation on any micronode. Only call this when no other micronode operations are running.

virtual bool DEP_MicroNode::requiresUpdate ( fpreal t ) const

inlinevirtual

requiresUpdate() specifies if the micro-node was dirtied, possibly based on the time t. By default, it returns isDirty() but subclasses override this to handle other conditions that make this micro-node requiring an update.

virtual void DEP_MicroNode::update ( fpreal t )

update() is used by users of micro-nodes to mark this node as clean at the given time t. By default, it simply marks it as no longer dirty but subclasses override this to do more work.
