Interface BinaryDelta

public interface BinaryDelta
Binary delta type.

DataType implementations that support binary deltas by returning a DeltaType implementation as the result of deltaType(BinaryDelta.class). Two values of such a data type can be diffed to create a binary delta. The binary delta can later be applied to the first value to calculate the second value.
