Public Member Methods
DLLLOCAL	QoreListNodeEvalOptionalRefHolder (const QoreListNode *exp, ExceptionSink *n_xsink)
	performs an optional evaluation of the list (sets the dereference flag)
DLLLOCAL	QoreListNodeEvalOptionalRefHolder (ExceptionSink *n_xsink)
	initializes an empty object and saves the ExceptionSink object
DLLLOCAL	~QoreListNodeEvalOptionalRefHolder ()
	clears the object (dereferences the old object if necessary)
DLLLOCAL void	assign (bool n_needs_deref, QoreListNode *n_val)
	assigns a new value and dereference flag to this object, dereferences the old object if necessary
DLLLOCAL void	assignEval (const QoreListNode *exp)
	assigns a new value by executing the given list and dereference flag to this object, dereferences the old object if necessary
DLLLOCAL void	assignEval (QoreListNode *exp)
	assigns a new value by executing the given list and dereference flag to this object, dereferences the old object if necessary
DLLLOCAL bool	canEdit () const
	returns true if the value being managed can be edited/updated
DLLLOCAL void	discard ()
	clears the object (dereferences the old object if necessary)
DLLLOCAL void	edit ()
	will create a unique list so the list can be edited

	returns a referenced value - the caller will own the reference More...
DLLLOCAL bool	needsDeref () const
	returns true if the object contains a temporary (evaluated) value that needs a dereference
DLLLOCAL	operator bool () const
	returns true if a QoreListNode object pointer is being managed, false if the pointer is 0

Detailed Description

For use on the stack only: manages result of the optional evaluation of a QoreListNode.

Member Function Documentation

getReferencedValue()

DLLLOCAL QoreListNode* QoreListNodeEvalOptionalRefHolder::getReferencedValue ( )

inline

returns a referenced value - the caller will own the reference

The list is referenced if necessary (if it was a temporary value)

Returns

the list value, where the caller will own the reference count

operator->()

DLLLOCAL const QoreListNode* QoreListNodeEvalOptionalRefHolder::operator-> ( ) const

inline

returns a pointer to the QoreListNode object being managed

if you need a referenced value, use getReferencedValue()

Returns

a pointer to the QoreListNode object being managed (or 0 if none)
