Constructors

IndexExpressionAst(IScriptExtent, ExpressionAst, ExpressionAst, Boolean)	Initializes a new instance of the IndexExpressionAst class.
IndexExpressionAst(IScriptExtent, ExpressionAst, ExpressionAst)	Construct an ast for an index expression.

Properties

Extent	The extent in the source this ast represents. (Inherited from Ast)
Index	Return the ast for the index expression. This value is never null.
NullConditional	Gets a value indicating whether ?[] operator is being used.
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)`. (Inherited from ExpressionAst)
Target	Return the ast for the expression being indexed. This value is never null.

Methods

Copy()	Copy the IndexExpressionAst 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. (Inherited from Ast)
