Arguments required to construct a vertex which represents the definition of a variable in the DataflowGraph|dataflow graph.

isVariableDefinitionVertex - to check if a vertex is a variable definition vertex

Properties

cds: undefined | ControlDependency[]

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

environment?: undefined

Does not require an environment, those are attached to the call

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.

indicesCollection?: ContainerIndicesCollection

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

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

Used to identify and separate different types of vertices.
