Class Sources::SourceNode

A source node for local data flow, that is, a node for which local data flow cannot provide any information about its inputs.

By default, functions, object and array expressions and JSX nodes are considered sources, as well as expressions that have non-local flow (such as calls and property accesses). Additional sources can be modelled by extending this class with additional subclasses.

Gets a read of any property on this node.

getAPropertyReference

Gets a reference (read or write) of property propName on this node.

getAPropertyReference

Gets a reference (read or write) of any property on this node.

getAPropertySource

Gets a source node whose value is stored in property prop of this node.

getAPropertyWrite

Gets a write of property propName on this node.

getAPropertyWrite

Gets a write of any property on this node.

getAnInstantiation

Gets a new call to this node.

getAnInvocation

from Node
getAPredecessor

Gets a data flow node from which data may flow to this node in one local step.

from Node
