Class SpinedBuffer<E,T_ARR>

java.lang.Object

com.annimon.stream.internal.SpinedBuffer<E,T_ARR>

All Implemented Interfaces:

java.lang.Iterable<E>

Direct Known Subclasses:

SpinedBuffer.Of, SpinedBuffer.OfDouble, SpinedBuffer.OfInt, SpinedBuffer.OfLong

public abstract class SpinedBuffer<E,T_ARR>
extends java.lang.Object
implements java.lang.Iterable<E>

Base class for a data structure for gathering elements into a buffer and then iterating them. Maintains an array of increasingly sized arrays, so there is no copying cost associated with growing the data structure.
