def callAst(callNode: NewCall, arguments: Seq[Ast], base: Option[Ast], receiver: Option[Ast]): Ast

Create an abstract syntax tree for a call, including CPG-specific edges required for arguments and the receiver.

Create an abstract syntax tree for a call, including CPG-specific edges required for arguments and the receiver.

Our call representation is inspired by ECMAScript, that is, in addition to arguments, a call has a base and a receiver. For languages other than Javascript, leave receiver empty for now.

Value parameters

arguments

arguments (without the base argument (instance))

base

the value to use as this in the method call.

callNode

the node that represents the entire call

receiver

the object in which the property lookup is performed
