org.netbeans.swing.tabcontrol.event
Class ArrayDiff

java.lang.Object
  org.netbeans.swing.tabcontrol.event.ArrayDiff

public final class ArrayDiff
extends Object
extends Object

Class representing a diff of two arrays. Note that it is not designed to work with arrays which contain the same element more than one time - in that case, the results are undefined.

Note the current implementation is unoptimized and fairly brute force.

Method Summary

static ArrayDiff createDiff(TabData[] old, TabData[] nue)
          Returns an ArrayDiff object if the two arrays are not the same, or null if they are

boolean equals(Object o)


Set<Integer> getAddedIndices()
          Returns the indices of objects in the new array which are not present in the old array

Set<Integer> getChangedIndices()
          Returns the indices of objects which differ in any way between the new and old array.

Set<Integer> getDeletedIndices()
          Returns the indices of objects in the old array which are not present in the new array.

Set<Integer> getMovedIndices()
          Returns the indices of objects which were in the old array and are also in the new array, but at a different index.

TabData[] getNewData()
          Get the array representing the new state

TabData[] getOldData()
          Get the array representing the old state

int hashCode()

Method Detail

getOldData

public TabData[] getOldData()

Get the array representing the old state

getNewData

public TabData[] getNewData()

Get the array representing the new state

createDiff

public static ArrayDiff createDiff(TabData[] old,
                                   TabData[] nue)

Returns an ArrayDiff object if the two arrays are not the same, or null if they are

getDeletedIndices

public Set<Integer> getDeletedIndices()

Returns the indices of objects in the old array which are not present in the new array. The resulting array's size will be that of the old array

getAddedIndices

public Set<Integer> getAddedIndices()

Returns the indices of objects in the new array which are not present in the old array

getChangedIndices

public Set<Integer> getChangedIndices()

Returns the indices of objects which differ in any way between the new and old array. The size of the result is Math.max(old.length, nue.length).

getMovedIndices

public Set<Integer> getMovedIndices()

Returns the indices of objects which were in the old array and are also in the new array, but at a different index. The indices returned are indices into the old array.

toString

Overrides:: toString in class Object

equals
