CacheObjectBinaryProcessorImpl | Binary processor implementation.
IgniteBinaryImpl | `IgniteBinary` implementation.
MetadataRequestMessage | As `DiscoveryCustomMessage` messages are delivered to client nodes asynchronously it is possible that server nodes are allowed to send to clients some BinaryObjects clients don't have metadata for.
MetadataResponseMessage | Carries latest version of metadata to client as a response for `MetadataRequestMessage`.
MetadataUpdateAcceptedMessage | Acknowledge message for `MetadataUpdateProposedMessage`: see its javadoc for detailed description of protocol.
MetadataUpdateProposedMessage | MetadataUpdateProposedMessage and `MetadataUpdateAcceptedMessage` messages make a basis for discovery-based protocol for exchanging `metadata` describing objects in binary format stored in Ignite caches.
