## 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

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

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

Returns
  the string value, where the caller will own the reference count

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

returns the object being managed

Returns
  the object being managed

DLLLOCAL const QoreStringNode* QoreStringNodeValueHelper::operator-> | ( |  | ) |
| inline
