ConstantExpressionAst Class

Definition

Namespace:

System.Management.Automation.Language

Assembly:

System.Management.Automation.dll

Package:

System.Management.Automation v7.4.0

The ast representing constant values, such as numbers. Constant values mean truly constant, as in, the value is always the same. Expandable strings with variable references (e.g. "$val") or sub-expressions (e.g. "$(1)") are not considered constant.

Constructors

ConstantExpressionAst(IScriptExtent, Object)

Construct a constant expression.

Properties

Extent	The extent in the source this ast represents. (Inherited from Ast)
Parent	The parent tree for this node. (Inherited from Ast)
StaticType	The static type of a constant is whatever type the value is, or if null, then assume it's typeof(object).
Value	The value of the constant. This property is null only if the expression represents the null constant.

Methods

Copy()	Copy the ConstantExpressionAst 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)
