Class AccuChopper<Component extends Accumulator<Part>,Part>

java.lang.Object
  com.varankin.io.stream.AccuChopper<Component,Part>

All Implemented Interfaces:

java.lang.Iterable<Component>

public final class AccuChopper<Component extends Accumulator<Part>,Part>
extends java.lang.Object
implements java.lang.Iterable<Component>

General purpose parser, trying to construct Component's from Part's. Component is considered completed, once it rejects next Part object. Parser starts consuming part(s) on getting Component over iterator. Parser retracts unused Part's from completed Component to reuse them for next Component instance.
