Class DataBlockCompressed

java.lang.Object
org.vast.data.AbstractDataBlock
org.vast.data.DataBlockCompressed
All Implemented Interfaces:
Serializable, DataBlock
public class DataBlockCompressed extends AbstractDataBlock

Carries data in compressed format. Data is uncompressed on the fly when one of the get methods is called, and set Methods are not implemented.
All data is casted to the correct types when requested.
