mapException

protected RpcException mapException(Exception e)

Description copied from class: AbstractCheckedFuture

Translates from an InterruptedException, CancellationException or ExecutionException thrown by get to an exception of type X to be thrown by checkedGet. Subclasses must implement this method.

If e is an InterruptedException, the calling checkedGet method has already restored the interrupt after catching the exception. If an implementation of AbstractCheckedFuture.mapException(Exception) wishes to swallow the interrupt, it can do so by calling Thread.interrupted().

Subclasses may choose to throw, rather than return, a subclass of RuntimeException to allow creating a CheckedFuture that throws both checked and unchecked exceptions.

Specified by:

mapException in class AbstractCheckedFuture<T,RpcException>

getBuffer

public io.netty.buffer.ByteBuf getBuffer()
