public boolean hasNext()
If the status of the reader indicates that there may be more Record
s available but have not yet reached the
current reader through the respective mirroring procedure, then the ForwardReader.waitAvailable(long, java.util.concurrent.TimeUnit)
is used with the timeout values defined by ForwardReader.getIteratorTimeout()
and ForwardReader.getIteratorTimeUnit()
hasNext
in interface java.util.Iterator<T extends Record>
Iterator.hasNext()
public T next()
the ForwardReader.get(long, java.util.concurrent.TimeUnit)
method is used to retrieve the next available
Record
. The timeout values used are the ones defined by ForwardReader.getIteratorTimeout()
and
ForwardReader.getIteratorTimeUnit()
. in case there is some error during the Record
retrieval or
the timeout expired, null is returned
next
in interface java.util.Iterator<T extends Record>
Iterator.next()
public void remove()
Operation is not supported. An IllegalStateException
is thrown upon invocation
