 org.infinispan.api.common.CacheOptions options,
 DataFormat dataFormat)

Method Details

executeOperation

public void executeOperation(io.netty.channel.Channel channel)

Description copied from class: RetryOnFailureOperation

Perform the operation-specific request/response I/O on the specified channel. If an error occurs during I/O, this class will detect it and retry the operation with a different channel by invoking the executeOperation method again.

Specified by:

executeOperation in class RetryOnFailureOperation<V>

Parameters:

channel - the channel to use for I/O

acceptResponse

public void acceptResponse(io.netty.buffer.ByteBuf buf,
 short status,
 HeaderDecoder decoder)

Specified by:

acceptResponse in class HotRodOperation<V>
