Package org.elasticsearch.index.translog

Class BufferedChecksumStreamOutput

java.lang.Object

java.io.OutputStream

org.elasticsearch.common.io.stream.StreamOutput

org.elasticsearch.index.translog.BufferedChecksumStreamOutput

All Implemented Interfaces:

java.io.Closeable, java.io.Flushable, java.lang.AutoCloseable

public final class BufferedChecksumStreamOutput
extends StreamOutput

Similar to Lucene's BufferedChecksumIndexOutput, however this wraps a StreamOutput so anything written will update the checksum
