Class DataFlow::SourceNode
A source node for local data flow, that is, a node from which local data flow is tracked.
This includes function invocations, parameters, object creation, and references to a property or global variable.
You can introduce new kinds of source nodes by defining new subclasses of DataFlow::SourceNode::Range
.
Examples:
obj.f // property access
Math.abs(x) // function calls
{ f: 12, g: 45 }; // object expressions
function fn(x) {} // functions and parameters
class C {} // classes
document // global variable access
<View/> // JSX literals
/[a-z]+/g; // regular expression literal
await x // await expression
import * as fs from 'fs';
import { readDir } from 'fs';
import("fs")
