Constructor Detail

NettyBytableDecoder

public NettyBytableDecoder()

Default constructor with max object size 256M.

NettyBytableDecoder

public NettyBytableDecoder(int maxObjectSize)

Creates a new decoder with the specified maximum object size.

Parameters:

maxObjectSize - the maximum byte length of the serialized object. if the length of the received object is greater than this value, StreamCorruptedException will be raised.
