Examples of com.lightcrafts.utils.SoftValueHashMap

com.lightcrafts.utils.SoftValueHashMap
SoftValueHashMap is a volatile cache that utilizes SoftReferences of the value itself rather than the key. The benefit over a WeakHashMap is that a WeakHashMap uses WeakReferences for keys. Since keys are often Strings, and Strings are often interned, there is the potential that an entry will never be garbage collected. Also, WeakReferences are garbage collected too frequently for the type of volatile caching for which SoftValueHashMap is intended.

            // Swing geometry
            setPreferredSize(new Dimension(source.getWidth(), source.getHeight()));
        }
        setOpaque(true);
