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

xsink

if 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

args	the arguments to the function
xsink	any 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.
