Class BitmapIndexImpl.CompressedBitmap

java.lang.Object

org.eclipse.jgit.internal.storage.file.BitmapIndexImpl.CompressedBitmap

All Implemented Interfaces:

Iterable<BitmapObject>, BitmapIndex.Bitmap

Enclosing class:

BitmapIndexImpl

public static final class BitmapIndexImpl.CompressedBitmap
extends Object
implements BitmapIndex.Bitmap

Wrapper for a EWAHCompressedBitmap and PackBitmapIndex.

For a EWAHCompressedBitmap bitmap representing a vector of bits, new CompressedBitmap(bitmap, bitmapIndex) represents the objects at those positions in bitmapIndex.packIndex.

CompressedBitmap

public CompressedBitmap(com.googlecode.javaewah.EWAHCompressedBitmap bitmap,
                        BitmapIndexImpl bitmapIndex)

Construct compressed bitmap for given bitmap and bitmap index

Parameters:

bitmap -

bitmapIndex -

Method Detail

or

public BitmapIndexImpl.CompressedBitmap or(BitmapIndex.Bitmap other)

Description copied from interface: BitmapIndex.Bitmap

Bitwise-OR the current bitmap with the value from the other bitmap.

Specified by:

or in interface BitmapIndex.Bitmap

Parameters:

other - the other bitmap

Returns:

a bitmap that is the bitwise-OR.

andNot

public BitmapIndexImpl.CompressedBitmap andNot(BitmapIndex.Bitmap other)

Description copied from interface: BitmapIndex.Bitmap

Bitwise-AND-NOT the current bitmap with the value from the other bitmap.

Specified by:

andNot in interface BitmapIndex.Bitmap

Parameters:

other - the other bitmap

Returns:

a bitmap that is the bitwise-AND-NOT.

xor

public BitmapIndexImpl.CompressedBitmap xor(BitmapIndex.Bitmap other)

Description copied from interface: BitmapIndex.Bitmap

Bitwise-XOR the current bitmap with the value from the other bitmap.

Specified by:

xor in interface BitmapIndex.Bitmap

Parameters:

other - the other bitmap

Returns:

a bitmap that is the bitwise-XOR.

iterator

public Iterator<BitmapObject> iterator()

Description copied from interface: BitmapIndex.Bitmap

Returns an iterator over a set of elements of type BitmapObject. The BitmapObject instance is reused across calls to Iterator.next() for performance reasons.

Specified by:

iterator in interface BitmapIndex.Bitmap

Specified by:

iterator in interface Iterable<BitmapObject>

Returns:

an Iterator.

retrieveCompressed

public com.googlecode.javaewah.EWAHCompressedBitmap retrieveCompressed()

Description copied from interface: BitmapIndex.Bitmap

Returns the corresponding raw compressed EWAH bitmap of the bitmap.

Specified by:

retrieveCompressed in interface BitmapIndex.Bitmap

Returns:

the corresponding EWAHCompressedBitmap
