AttributedExpressionAst Class

Definition

Namespace:

System.Management.Automation.Language

Assembly:

System.Management.Automation.dll

Package:

System.Management.Automation v7.4.0

The ast that represents an expression with an attribute. This is normally allowed only on parameters or variables being assigned, e.g. [Parameter()]$PassThru or [ValidateScript({$true})$abc = 42.

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). (Inherited from ExpressionAst)

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)
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)
