Class API::CallNode

A CallCfgNode that is connected to the API graph.

Can be used to reason about calls to an external API in which the correlation between parameters and/or return values must be retained.

The member predicates getParameter, getKeywordParameter, getReturn, and getInstance mimic the corresponding predicates from API::Node. These are guaranteed to exist and be unique to this call.

Predicates

getAParameter	Gets the API node for a parameter of this invocation.
getKeywordParameter	Gets the API node for the keyword parameter `name` of this invocation.
getNumArgument	Gets the number of positional arguments of this call.
getParameter	Gets the API node for the `i`th parameter of this invocation.
getParameter	Gets the API node for the parameter that has index `i` or has keyword `name`.
getReturn	Gets the API node for the return value of this call.
getSelfParameter	Gets the object that this method-call is being called on, if this is a method-call
