Class CompressedXContent

java.lang.Object

org.elasticsearch.common.compress.CompressedXContent

public final class CompressedXContent
extends Object

Similar class to the String class except that it internally stores data using a compressed representation in order to require less permanent memory. Note that the compressed string might still sometimes need to be decompressed in order to perform equality checks or to compute hash codes.
