C# Class Rhino.Ast.XmlRef

Base class for E4X XML attribute-access or property-get expressions.

Base class for E4X XML attribute-access or property-get expressions. Such expressions can take a variety of forms. The general syntax has three parts:

optional: an @
optional: a namespace (a Name ) and double-colon
required: either a Name or a bracketed [expression]

The property-name expressions (examples: ns::name , @name ) are represented as XmlPropRef nodes. The bracketed-expression versions (examples: ns::[name] , @[name] ) become XmlElemRef nodes.

This node type (or more specifically, its subclasses) will sometimes be the right-hand child of a PropertyGet node or an XmlMemberGet node. The XmlRef node may also be a standalone primary expression with no explicit target, which is valid in certain expression contexts such as company..employee.(@id < 100) - in this case, the @id is an XmlRef that is part of an infix '<' expression whose parent is an XmlDotQuery node.

Méthode	Description
GetAtPos ( ) : int	Returns position of `@` -token, or -1 if this is not an attribute-access expression.
GetColonPos ( ) : int	Returns position of `::` token, or -1 if not present. It will only be present if the namespace node is non- `null` .
GetNamespace ( ) : Name	Return the namespace. Return the namespace. May be `@null` .
IsAttributeAccess ( ) : bool	Returns `true` if this expression began with an `@` -token.
SetAtPos ( int atPos ) : void	Sets position of `@` -token, or -1
SetColonPos ( int colonPos ) : void	Sets position of `::` token, or -1 if not present
SetNamespace ( Name @namespace ) : void	Sets namespace, and sets its parent to this node. Sets namespace, and sets its parent to this node. Can be `null` .
