Class BodyCompressionMethod

java.lang.Object

public final class BodyCompressionMethod extends Object
Provided for forward compatibility in case we need to support different strategies for compressing the IPC message body (like whole-body compression rather than buffer-level) in the future

    • BUFFER

      public static final byte BUFFER
      Each constituent buffer is first compressed with the indicated compressor, and then written with the uncompressed length in the first 8 bytes as a 64-bit little-endian signed integer followed by the compressed buffer bytes (and then padding as required by the protocol). The uncompressed length may be set to -1 to indicate that the data that follows is not compressed, which can be useful for cases where compression does not yield appreciable savings.
