Methods

addInput(T nodeValue) → Node<T>?
Add a node to the inputs if it has not been added yet.
override
addOutput(T nodeValue) → Node<T>?
Add a node to the outputs if it has not been added yet.
override
containsInput(T nodeValue) → bool
Returns true if nodeValue is a inputs.
override
containsInputNode(Node<T> node) → bool
Returns true if node is a inputs.
containsOutput(T nodeValue) → bool
Returns true if outputs contains a Node with nodeValue.
override
containsOutputNode(Node<T> node) → bool
Returns true if outputs contains node.
dependencies({bool includeThisInputs = true, int? maxDepth, Iterable<Node<T>>? ignore}) → List<Node<T>>
Returns all the dependencies.
disposeGraph() → void
Disposes the graph.
getInput(T nodeValue) → Node<T>?
Gets a Node in the inputs.
getOrAddInput(T nodeValue) → Node<T>
Gets a Node in the inputs or add it.
getOrAddOutput(T nodeValue) → Node<T>
Gets a Node in the outputs or add it.
getOutput(T nodeValue) → Node<T>?
Gets a Node in the outputs.
inputsInDepth({int? maxDepth, bool bfs = false, Iterable<Node<T>>? ignore}) → List<Node<T>>
Returns all the inputs in depth, scanning all the inputs of inputs.
inputsInDepthIntersection(Node<T>? other) → List<Node<T>>
isInput(T targetValue) → bool
Returns true if targetValue is an input of this node.
isInputInShortestPathToRoot(Node target) → bool
Returns true if target is an input in the shortestPathToRoot.
isInputNode(Node<T> target) → bool
Returns true if target is an input of this node.
isOutput(T targetValue) → bool
Returns true if targetValue is an output of this node.
isOutputNode(Node<T> target) → bool
Returns true if target is an output of this node.
markAsTarget() → void
Marks this node as a target.
missingDependencies(Iterable<Node<T>> knownDependencies, {int? maxDepth}) → List<Node<T>>
Returns all the missing dependencies not present in the knownDependencies parameter.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
outputsInDepth({int? maxDepth, bool bfs = false, Iterable<Node<T>>? ignore}) → List<Node<T>>
Returns all the outputs in depth, scanning all the outputs of outputs.
outputsInDepthIntersection(Node<T>? other) → List<Node<T>>
reset() → void
Resets this node for a path scan. Clears _target and attachment.
override
resolveAllPathsToRoot({int maxExpansion = 3}) → List<List<Node<T>>>
Resolves all the paths to the root from this node.
resolveShortestPathToRoot() → List<Node<T>>
Resolves the shortest path to root from this node. Since inputs is populated in BFS, the 1st input is one of the closest to the root.
roots({bool bfs = false}) → List<Node<T>>
sideRoots({int? maxDepth}) → List<Node<T>>
Return the list of side roots after this Node.
toString() → String
A string representation of this object.
override

Operators

operator ==(Object other) → bool
The equality operator.
