Member Function Documentation

dependsOn()

template<typename... Ns>

void dispenso::Node::dependsOn ( Ns &...  nodes )

inline

Make this node depends on nodes. This is not concurrency safe.

Parameters

nodes

predecessors of the node

Definition at line 246 of file graph.h.

dependsOnOneNode()

void dispenso::Node::dependsOnOneNode ( Node &  node )

inlineprotected

Definition at line 330 of file graph.h.

forEachDependent() [1/2]

template<class F >

void dispenso::Node::forEachDependent ( F &&  func )

inline

apply an func to each dependent of the node This is not concurrency safe.

Parameters

func	a functor with signature void(Node&)

Definition at line 274 of file graph.h.

forEachDependent() [2/2]

template<class F >

void dispenso::Node::forEachDependent ( F &&  func ) const

inline

apply an func to each dependent of the node

Parameters

func	a functor with signature void(const Node&)

Definition at line 263 of file graph.h.

isCompleted()

bool dispenso::Node::isCompleted ( ) const

inline

Return true if node is completed. New node always incomplete. If node was invoked it become completed. this state can be changed by calling setIncomplete() Concurrency safe.

Definition at line 291 of file graph.h.

numPredecessors()

size_t dispenso::Node::numPredecessors ( ) const

inline

Return the number of nodes this node depends on. Concurrency safe.

Definition at line 282 of file graph.h.

run()

void dispenso::Node::run ( ) const

inline

Invoke the type-erased functor. Change competed state of the node to "Incomplete". Concurrency safe.

Definition at line 253 of file graph.h.

setCompleted()

void dispenso::Node::setCompleted ( ) const

inline

Mark node completed. Concurrency safe. This methods should never be called concurrent to when the graph execution is happening

Definition at line 314 of file graph.h.

setIncomplete()

bool dispenso::Node::setIncomplete ( ) const

inline

Mark node incomplete. (that allows reevaluate this node again). Concurrency safe. This methods should never be called concurrent to when the graph execution is happening

Returns

true if state was changed.

Definition at line 301 of file graph.h.
