Detailed Description

parse type: reference to a lvalue expression

This type could be passed to a builtin function. To get and set the value of the reference, use the TypeSafeReferenceHelper class. To create a reference argument to pass to a user or builtin function, use the ReferenceArgumentHelper class.

Constructor & Destructor Documentation

DLLLOCAL ReferenceNode::ReferenceNode

(

AbstractQoreNode *

exp

)

creates the ReferenceNode object with the given lvalue expression

Parameters:

exp	must be a parse expression for an lvalue

Member Function Documentation

virtual DLLEXPORT int ReferenceNode::getAsString	(	QoreString &	str,
		int	foff,
		class ExceptionSink *	xsink
	)		const [virtual]

concatenate the verbose string representation of the value to an existing QoreString

used for n and N printf formatting

Parameters:

str	the string representation of the type will be concatenated to this QoreString reference
foff	for multi-line formatting offset, -1 = no line breaks (ignored in this version of the function)
xsink	ignored in this version of the function

Returns:

this implementation of the function always returns 0 for no error raised

Implements AbstractQoreNode.

virtual DLLEXPORT QoreString* ReferenceNode::getAsString	(	bool &	del,
		int	foff,
		class ExceptionSink *	xsink
	)		const [virtual]

returns a QoreString giving the verbose string representation of the value

Used for n and N printf formatting. Do not call this function directly; use the QoreNodeAsStringHelper class (defined in QoreStringNode.h) instead

Parameters:

del	if this is true when the function returns, then the returned QoreString pointer should be deleted, if false, then it must not be
foff	for multi-line formatting offset, -1 = no line breaks (ignored in this version of the function)
xsink	ignored in this version of the function

See also:

QoreNodeAsStringHelper

Implements AbstractQoreNode.

DLLLOCAL AbstractQoreNode* ReferenceNode::getExpression

(

)

const [inline]

returns the lvalue expression for this object

Returns:

the lvalue expression for this object
