Constructors

AttributedExpressionAst(IScriptExtent, AttributeBaseAst, ExpressionAst)

Construct an attributed expression.

Properties

Attribute

The attribute or type constraint for this expression. This property is never null.

Child

The expression that has an attribute or type constraint applied to it. This property is never null.

Extent

The extent in the source this ast represents.

(Inherited from Ast)
Parent

The parent tree for this node.

(Inherited from Ast)
StaticType

By default, the static type of an expression is unknown and hence we assume typeof(object).

Methods

Copy()

Copy the AttributedExpressionAst instance

Find(Func<Ast,Boolean>, Boolean)

Traverse the entire Ast, returning the first node in the tree for which predicate returns true.

(Inherited from Ast)
FindAll(Func<Ast,Boolean>, Boolean)

Traverse the entire Ast, returning all nodes in the tree for which predicate returns true.

(Inherited from Ast)
SafeGetValue()

Constructs the resultant object from the AST and returns it if it is safe.

(Inherited from Ast)
ToString()

Formats the ast and returns a string.

(Inherited from Ast)
Visit(AstVisitor)

Visit each node in the Ast, calling the methods in astVisitor for each node in the ast.

(Inherited from Ast)
Visit(ICustomAstVisitor)

Visit the Ast using a visitor that can choose how the tree traversal is performed. This visit method is for advanced uses of the visitor pattern where an AstVisitor is insufficient.
