Detailed Description

this class is used to safely manage calls to AbstractQoreNode::getStringRepresentation() when a QoreStringNode value is needed, stack only, may not be dynamically allocated

the QoreStringNode value returned by this function is managed safely in an exception-safe way with this class

printf("str='%s'\n", str->getBuffer());
return str.getReferencedValue();

DLLLOCAL const QoreStringNode* QoreStringNodeValueHelper::operator* ( )
inline

returns the object being managed

Returns
the object being managed
DLLLOCAL const QoreStringNode* QoreStringNodeValueHelper::operator-> ( )
inline

returns the object being managed
