canManageAutoRead

public boolean canManageAutoRead()

Description copied from interface: ResponseHandler

Tells whether this response handler is able to manage auto-read of the underlying connection using Connection.enableAutoRead() and Connection.disableAutoRead().

Implementations can use auto-read management to apply network-level backpressure when receiving a stream of records. There should only be a single such handler active for a connection at one point in time. Otherwise, handlers can interfere and turn on/off auto-read racing with each other. InboundMessageDispatcher is responsible for tracking these handlers and disabling auto-read management to maintain just a single auto-read managing handler per connection.

Specified by:

canManageAutoRead in interface ResponseHandler

disableAutoReadManagement

public void disableAutoReadManagement()

Description copied from interface: ResponseHandler

If this response handler is able to manage auto-read of the underlying connection, then this method signals it to stop changing auto-read setting for the connection.
