GetValueOperation

public GetValueOperation(OperationContext operationContext,
 String counterName,
 boolean useConsistentHash)

Method Details

executeOperation

protected 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<Long>

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<Long>

fetchChannelAndInvoke

protected void fetchChannelAndInvoke(int retryCount,
 Set<SocketAddress> failedServers)

Overrides:

fetchChannelAndInvoke in class RetryOnFailureOperation<T>

handleException

protected Throwable handleException(Throwable cause,
 io.netty.channel.Channel channel,
 SocketAddress address)

Overrides:

handleException in class RetryOnFailureOperation<T>

addParams

protected void addParams(StringBuilder sb)

Overrides:

addParams in class HotRodOperation<T>
