Interface DataflowGraphVertexValue

Marker vertex for a value in the dataflow of the program. This does not contain the value of the referenced constant as this is available with the id in the NormalizedAst|normalized AST (or more specifically the AstIdMap).

If you have a DataflowGraph|dataflow graph named graph with an AstIdMap and a value vertex object with name value the following Code should work:

Example

const node = graph.idMap.get(value.id)

This then returns the corresponding node in the NormalizedAst|normalized AST, for example, an RNumber or RString.

This works similarly for IdentifierReference|identifier references for which you can use the IdentifierReference#nodeId|nodeId.

Properties

cds

cds: undefined | ControlDependency[]

See

ControlDependency - the collection of control dependencies which have an influence on whether the vertex is executed.

Optional Readonlyenvironment

environment?: undefined

The environment in which the vertex is set.

id

id: NodeId

The id of the node (the id assigned by the ParentInformation decoration). This unanimously identifies the vertex in the DataflowGraph|dataflow graph as well as the corresponding NormalizedAst|normalized AST.

OptionalindicesCollection

indicesCollection?: ContainerIndicesCollection

this attribute links a vertex to indices (pointer links) it may be affected by or related to

Optionallink

link?: DataflowGraphVertexAstLink

Describes the collection of AST vertices that contributed to this vertex. For example, this is useful with replacement operators, telling you which assignment operator caused them

Readonlytag

tag: Value

Used to identify and separate different types of vertices.
