Method Detail

parts

public abstract Expr parts()

How many 'parts' are represented by this SeqCall. Should be Expr.literal(Fraction.ONE) for all but Part.

isIndeterminate

public abstract boolean isIndeterminate()

True if the result of parts() can not be used for fractionalization.

accept

public abstract <T> SeqCall 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.
