                              byte[] toAppend,
                              int offset,
                              int count)

estimateArraySize

public static int estimateArraySize(byte[] array)

estimateVIntSize

public static int estimateVIntSize(int value)

writeOptionalArray

public static void writeOptionalArray(io.netty.buffer.ByteBuf buf,
                                      byte[] toAppend)

                             int i)

writeSignedVInt

public static void writeSignedVInt(io.netty.buffer.ByteBuf buf,

estimateXidSize

public static int estimateXidSize(Xid xid)

Estimates the Xid encoding size.

If the instance is a RemoteXid, the estimation is accurate. Otherwise, the max size is used.

Parameters:

xid - the Xid instance to test.

Returns:

the estimated size.

writeXid

public static void writeXid(io.netty.buffer.ByteBuf buf,
                            Xid xid)

Writes the Xid to the ByteBuf.

Parameters:

buf - the buffer to write to.

xid - the Xid to encode
