Assembly:

System.Management.Automation.dll

Package:

Constructors

ParameterAst(IScriptExtent, VariableExpressionAst, IEnumerable<AttributeBaseAst>, ExpressionAst)

Construct a parameter ast from the name, attributes, and default value.

Properties

Attributes	The asts for any attributes or type constraints specified on the parameter.
DefaultValue	The ast for the default value of the parameter, or null if no default value was specified.
Extent	The extent in the source this ast represents. (Inherited from Ast)
Name	The variable path for the parameter. This property is never null.
Parent	The parent tree for this node. (Inherited from Ast)
StaticType	Returns the type of the parameter. If the parameter is constrained to be a specific type, that type is returned, otherwise typeof(object) is returned.

Methods

Copy()	Copy the ParameterAst 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)
