public interface DeltaCompressor
The DeltaCompressor interface provides the capability of comparing two in-memory buffers containing an old and a new value, and producing a result (called a "delta") that can be applied to the old value to create the new value.
Method Summary | |
---|---|
ReadBuffer |
applyDelta(ReadBuffer bufOld, ReadBuffer bufDelta) Apply a delta to an old value in order to create a new value. |
ReadBuffer |
extractDelta(ReadBuffer bufOld, ReadBuffer bufNew) Compare an old value to a new value and generate a delta that represents the changes that must be made to the old value in order to transform it into the new value. |
