Class BufferedChecksumStreamInput

java.lang.Object

java.io.InputStream

org.elasticsearch.common.io.stream.StreamInput

org.elasticsearch.common.io.stream.FilterStreamInput

org.elasticsearch.index.translog.BufferedChecksumStreamInput

All Implemented Interfaces:

java.io.Closeable, java.lang.AutoCloseable

public final class BufferedChecksumStreamInput
extends FilterStreamInput

Similar to Lucene's BufferedChecksumIndexInput, however this wraps a StreamInput so anything read will update the checksum
