Constructors

CommandExpressionAst(IScriptExtent, ExpressionAst, IEnumerable<RedirectionAst>)

Construct a command that wraps an expression.

Properties

Expression	The ast for the expression that is or starts a pipeline. 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)
Redirections	The possibly empty collection of redirections for this command. (Inherited from CommandBaseAst)

Methods

Copy()	Copy the CommandExpressionAst 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)
