Example 1
Source File: SetEntryWithComputedValueProcessor.java    From cache2k with Apache License 2.0 6 votes vote down vote up 
@Override
public String process(MutableEntry<K, String> entry, Object... arguments) {
    StringBuffer computedValue = new StringBuffer();
    if (valuePrefix != null) {
        computedValue.append(valuePrefix);
    }
    computedValue.append(entry.getKey().toString());
    if (valuePostfix != null) {
        computedValue.append(valuePostfix);
    }

    // Not trying to be efficient here.
    // For testing purposes in entry processor, follow the set with a get.
    // It would be more efficient to just return value that was passed to setValue.
    // This is testing the entry processor path of create or update an entry followed by an entry access.
    entry.setValue(computedValue.toString());
    return entry.getValue();
