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.

void DEP_MicroNode::addExplicitInput ( DEP_MicroNode inp,
bool  check_dup 
)

Methods for manipulating explicit edges.

Add an input that this micronode depends on, with control on whether to check for duplicates.

void DEP_MicroNode::addExplicitInput ( DEP_MicroNode inp)
inline

Add an input that this micronode depends on.

Definition at line 109 of file DEP_MicroNode.h.

virtual void DEP_MicroNode::becameDirty ( DEP_MicroNode src,
const DEP_PropagateData propdata

Callbacks for what to do when the micronode becomes dirty. Derived micronodes can override this. Note that it requires knowledge of who made it dirty as they may behave differently. Currently used by OP_Node::propagateDirtyMicroNode

Reimplemented in OP_DataMicroNode, SIM_SimulationMicroNode, OP_ParmMicroNode, and OP_EventMicroNode.

Definition at line 159 of file DEP_MicroNode.h.

Global control whether dependencies can be cleared.

Definition at line 235 of file DEP_MicroNode.h.

inlinestatic

Global control whether we can evaluate exports.

Definition at line 239 of file DEP_MicroNode.h.

virtual void DEP_MicroNode::clearInputs ( )
inlinevirtual

Clear all inputs, including any state data related to them. Default implementation just calls clearExplicitInputs() and setTimeDependent(false).

Reimplemented in PRM_ParmMicroNode, OP_DataMicroNode, and VOP_ErrorMicroNode.

Definition at line 76 of file DEP_MicroNode.h.

virtual void DEP_MicroNode::dump ( std::ostream &  os,

void DEP_MicroNode::dumpAsDOT ( std::ostream &  os,
const char *  prefix = 0,
int  indent_level = 0 
) const

Dump the contents is a manner more suitable for DOT.

virtual void DEP_MicroNode::evaluateExports ( )
inlineprotectedvirtual

evaluateExports() is called after isExporting() is noted to be true during a dirty propagation pass initiated by dirtySubtree().

Reimplemented in OP_DataMicroNode.

Definition at line 263 of file DEP_MicroNode.h.

void DEP_MicroNode::getExplicitInputs ( DEP_MicroNodeList inputs) const

Get list of all non-null explicit inputs.

Get list of all non-null explicit outputs.

virtual void DEP_MicroNode::getInputs ( DEP_MicroNodeList inputs) const
virtual

Get list of all our non-null inputs, both implicit and explicit. The base class returns the list of explicit inputs.

Reimplemented in VIS_MountMicroNode, VIS_ParmsMicroNode, OP_DataMicroNode, VOP_ErrorMicroNode, VOP_ExportedParmLayoutMicroNode, and VOP_ParmDSMicroNode.

virtual int64 DEP_MicroNode::getMemoryUsage ( bool  inclusive) const
virtual

Obtain approximate memory usage.

inline

Get the number of non-null inputs.

Definition at line 117 of file DEP_MicroNode.h.

inline

Get the number of non-null outputs.

Definition at line 125 of file DEP_MicroNode.h.

virtual void DEP_MicroNode::getOutputs ( DEP_MicroNodeList outputs) const
virtual

Get list of all our non-null outputs, both implicit and explicit. The base class returns the list of explicit outputs.

Reimplemented in VIS_MountMicroNode, VIS_ParmsMicroNode, OP_DataMicroNode, OP_ParmMicroNode, VOP_ErrorMicroNode, VOP_ParmDSMicroNode, and VOP_DataMicroNode.

bool DEP_MicroNode::inheritTimeDependentFromExplicitInputs ( )

Set time dependent flag if any explicit inputs are set. Returns true if any explicit inputs are true.

bool DEP_MicroNode::inheritTimeInterestedFromExplicitInputs ( )

Set time interested flag if any explicit inputs are set. Returns true if any explicit inputs are true.

bool DEP_MicroNode::isDirty ( ) const
inline

Flag accessors.

Definition at line 207 of file DEP_MicroNode.h.

virtual bool DEP_MicroNode::isEvaluating ( ) const
inlineprotectedvirtual

These methods are overriden by subclasses to be used by the dirty propagation algorithm.Used to determine if a micronode is currently evaluating. If this returns true, during dirty propagation, it will prevent dependencies from being removed from it.

Reimplemented in OP_DataMicroNode.

Definition at line 258 of file DEP_MicroNode.h.

virtual bool DEP_MicroNode::isExporting ( ) const
inlineprotectedvirtual

Used to determine if a micronode requires its exports to be evaluated during the propagation pass.

static SYS_FORCE_INLINE bool DEP_MicroNode::isSameTime ( fpreal  a,
fpreal  b

bool DEP_MicroNode::markVisitPass ( int  pass)
inline

Mark this micronode as having seen the given global dirty counter. Returns false if we've already seen it.

Definition at line 169 of file DEP_MicroNode.h.

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_visitCalled for each micronode that is dirtied
only_outputsIf 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.

Reimplemented in OP_DataMicroNode, and DEP_TimedMicroNode.

void DEP_MicroNode::setDirty ( bool  flag,
bool  allow_clear = true

void DEP_MicroNode::traverseAncestorInputs ( const TraverseVisitor visitor) const

Traverse all ancestor inputs of this micronode.

virtual void DEP_MicroNode::update ( fpreal  t)
inlinevirtual

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.
