Class SingleChunkIndexInput

java.lang.Object
  org.apache.lucene.store.DataInput
      org.apache.lucene.store.IndexInput
          org.infinispan.lucene.SingleChunkIndexInput

All Implemented Interfaces:

Closeable, Cloneable

public final class SingleChunkIndexInput
extends org.apache.lucene.store.IndexInput

SingleChunkIndexInput can be used instead of InfinispanIndexInput to read a segment when it has a size small enough to fit in a single chunk. In this quite common case for some segment types we don't need the readLock to span multiple chunks, the pointer to the buffer is safe enough. This leads to an extreme simple implementation.

4.0
