Interface ITransducer<B,C>

Type Parameters:

B - The type of data processed by an input process

C - The type of data processed by the transduced process

All Known Implementing Classes:

ATransducer

public interface ITransducer<B,C>

A Transducer transforms a reducing function of one type into a reducing function of another (possibly the same) type, applying mapping, filtering, flattening, etc. logic as desired.

Method Summary

Methods

Modifier and Type	Method and Description
<R> IReducingFunction<R,C>	apply(IReducingFunction<R,? super B> rf) Transforms a reducing function of B into a reducing function of C.
<A> ITransducer<A,C>	comp(ITransducer<A,? super B> right) Composes a transducer with another transducer, yielding a new transducer.

Method Detail

apply

<R> IReducingFunction<R,C> apply(IReducingFunction<R,? super B> rf)

Transforms a reducing function of B into a reducing function of C.

Type Parameters:

R - The result type of both the input and the output reducing functions

Parameters:

rf - The input reducing function

Returns:

The transformed reducing function

comp

<A> ITransducer<A,C> comp(ITransducer<A,? super B> right)

Composes a transducer with another transducer, yielding a new transducer.

Type Parameters:

A - the type of input processed by the reducing function the composed transducer returns when applied

Parameters:

right - the transducer to compose with this transducer

Returns:

A new composite transducer
