Constructor Detail

ArrayDiffBuilder

public ArrayDiffBuilder(ArrayFunctions<A> functions)

Constructs an array diff builder with the given array functions.

Parameters:

functions - array functions

Method Detail

diff

public ArrayDiff<A> diff(A original,
                         A modified)

Calculates a diff between the original and modified array. Applying the resulting diff to the original array will result in the modified array. There is no guarantee that the given diff is minimal in size; but a best effort is made.

Parameters:

original - original (old) array

modified - modified (new) array

Returns:

diff between new and old array

getBuilder

public ArrayDiffBuilder.UpdateBuilder<A> getBuilder()

Constructs new update builder. Can be used to construct custom update lists; in general, the diff method is recommended.

Returns:

update builder

read

public ArrayDiff<A> read(DataInput input)
                  throws java.io.IOException

Reads a diff from the given input stream.

Parameters:

input - input stream

Returns:

deserialized array diff

Throws:

java.io.IOException - if an I/O error occurs
