Re: Best way to track if key was read more than X times?

[John Smith]

For those who are curious I did it like this...

Basically MyTuple is just "value" class that has two properties, the actual
value to be stored in the cache and a counter.

public class TestEntryProcessor implements EntryProcessor<String,
MyTuple, MyTuple> {
        @Override public MyTuple process(MutableEntry<String, MyTuple>
e, Object... args) {
            if(e.exists()) {
                MyTuple tuple = e.getValue();

                if(tuple.verificationCount-- == 0) {
                    e.remove();

                    return null;
                } else {
                    e.setValue(tuple);

                    return tuple;
                }
            } else {
                return null;
            }
        }
    }
