public interface Mapping<D,R,C>

A data transformer which takes individual data items of one type (the "arguments"), maps them to zero or more items of a second type (the "solutions") and pushes the solutions into a downstream Sink

Method Summary

Methods

Modifier and Type	Method and Description
void	apply(D arg, Sink<R> solutions, C context) Applies the mapping to a single argument, producing zero or more solutions and passing them into a downstream Sink
boolean	isTransparent()

Method Detail

isTransparent

boolean isTransparent()

Returns:

whether this function is referentially transparent w.r.t. all of its parameters.

apply

void apply(D arg,
         Sink<R> solutions,
         C context)
           throws RippleException

Applies the mapping to a single argument, producing zero or more solutions and passing them into a downstream Sink

Parameters:

arg - the argument data item

solutions - the solutions the argument is mapped to

context - a helper object providing context (may be null)

Throws:

RippleException - if a data handling error occurs
