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 |
| FindAll(Func<Ast,Boolean>, Boolean) |
Traverse the entire Ast, returning all nodes in the tree for which |
| 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 |
| 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) |
