Class Chunk<T>

java.lang.Object

com.github.difflib.patch.Chunk<T>

Type Parameters:

T - The type of the compared elements in the 'lines'.

All Implemented Interfaces:

Serializable

public final class Chunk<T>
extends Object
implements Serializable

Holds the information about the part of text involved in the diff process

Text is represented as Object[] because the diff engine is capable of handling more than plain ascii. In fact, arrays or lists of any type that implements hashCode() and equals() correctly can be subject to differencing using this library.
