Description copied from interface: FunctionCalls.CallInfo

Returns the result register.

Specified by:

getResultRegister in interface FunctionCalls.CallInfo

getSourceNode

public AbstractNode getSourceNode()

Description copied from interface: FunctionCalls.CallInfo

Returns the node where the call originates from. Note that this may be an indirect call via call/apply.

Specified by:

getSourceNode in interface FunctionCalls.CallInfo

getUnknownArg

public Value getUnknownArg()
