Constructors

PipelineBaseAst(IScriptExtent)

Initialize the common parts of a PipelineBaseAst.

Properties

Extent

The extent in the source this ast represents.

(Inherited from Ast)
Parent

The parent tree for this node.

(Inherited from Ast)

Methods

Copy()

Duplicates the AST, allowing it to be composed into other ASTs.

(Inherited from Ast)
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)
GetPureExpression()

If the pipeline represents a pure expression, the expression is returned, otherwise null is returned.

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.
