Description copied from class: AstNode

Visitor pattern implementation for transformations. Each AstNode accepts a TransformVisitor and a value, and returns an instance of its own type (ie, Seq.accept(tv, "A") returns a Seq). The 't' parameter is a closure.

Specified by:

accept in class Comp

accept

public <RESULT,CLOSURE> RESULT accept(ValueVisitor<RESULT,CLOSURE> v,
                                      CLOSURE cl)

Description copied from class: AstNode

Visitor pattern implementation for computations. Each AstNode accepts a ValueVisitor and a closure, and returns an object of the appropriate result type.

Specified by:

accept in class AstNode

build

public Par build(List<ParCall> children)

Factory: creates new Par only if it would differ from this.
