All Implemented Interfaces:

GridNioFilter

public class GridConnectionBytesVerifyFilter
extends GridNioFilterAdapter

Verifies that first bytes received in accepted (incoming) NIO session are equal to GridUtils.GG_HEADER.

First U.GG_HEADER.length bytes are consumed by this filter and all other bytes are forwarded through chain without any modification.
