Properties

Extent

The extent in the source this ast represents.

(Inherited from Ast)
NestedAst

Sometimes a valid ast is parsed successfully within the extent that this error expression represents. Those asts are contained in this collection. This collection may contain other error asts. This collection may be null when no asts were successfully constructed within the extent of this error 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 ErrorExpressionAst 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)
SafeGetValue(Boolean)

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.
