VariableExpressionAst Class

Definition

The ast representing a variable reference, either normal references, e.g. $true, or splatted references @PSBoundParameters.

Constructors

VariableExpressionAst(IScriptExtent, String, Boolean)

Construct a variable reference.

VariableExpressionAst(IScriptExtent, VariablePath, Boolean)

Construct a variable reference with an exising VariablePath (rather than construct a new one.)

Properties

Extent

The extent in the source this ast represents.

(Inherited from Ast)
Parent

The parent tree for this node.

(Inherited from Ast)
Splatted

True if splatting syntax was used, false otherwise.

StaticType

By default, the static type of an expression is unknown and hence we assume typeof(object).

(Inherited from ExpressionAst)
VariablePath

The name of the variable. This property is never null.

Methods

Copy()

Copy the VariableExpressionAst 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)
IsConstantVariable()

Check if the variable is one of $true, $false and $null

SafeGetValue()

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.
