Examples of HMapIDW

edu.umd.cloud9.io.map.HMapIDW

Writable representing a map where keys are ints and values are doubles.

One notable feature of this class is the ability to support lazy decoding, controlled by the {@link #setLazyDecodeFlag(boolean)} method. In lazy decoding mode, when an object of thistype is deserialized, key-value pairs are not inserted into the map, but rather held in arrays. The reduces memory used in cases where random access to values is not required. In lazy decoding mode, the raw keys and values may be fetched by the {@link #getKeys()} and {@link #getValues()}methods, respectively. The map can be subsequently populated with the {@link #decode()} method.
