Detailed Description

a call reference to a user function

Member Function Documentation

◆ derefImpl()

virtual DLLLOCAL bool FunctionCallReferenceNode::derefImpl ( ExceptionSink xsink)
privatevirtual

decrements the reference count

deletes the object when the reference count = 0. The ExceptionSink argument is needed for those types that could throw an exception when they are deleted (ex: QoreObject)

Parameters
xsinkif an error occurs, the Qore-language exception information will be added here
Returns
true if the object can be deleted, false if not (externally-managed)

Reimplemented from AbstractQoreNode.

◆ execValue()

virtual DLLLOCAL QoreValue FunctionCallReferenceNode::execValue ( const QoreListNode args,
ExceptionSink xsink 
) const
virtual

pure virtual function for executing the function reference

executes the function reference and returns the value returned

Parameters
argsthe arguments to the function
xsinkany Qore-language exception thrown (and not handled) will be added here
Returns
a pointer to an AbstractQoreNode, the caller owns the reference count returned (can also be nullptr)

Reimplemented from LocalFunctionCallReferenceNode.
