accept

public <T> OptCall accept(TransformVisitor<T> v,
                          T t)

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 AstNode

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 OptCall build(Expr matcher,
                     Comp child)

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