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.

Method Detail

hasChanges

boolean hasChanges()

Returns whether the two values used to create this instance are different. It is equivalent to !DeltaType.noChange().equals(this) .

Returns:

true if this delta has an effect

length
