Interface BitmapIndex.BitmapBuilder

All Superinterfaces:

BitmapIndex.Bitmap, Iterable<BitmapObject>

Enclosing interface:

BitmapIndex

public static interface BitmapIndex.BitmapBuilder
extends BitmapIndex.Bitmap

A builder for a bitmap. The bitwise operations update the builder and return a reference to the current builder.

Method Summary

Modifier and Type	Method	Description
BitmapIndex.BitmapBuilder	addObject(AnyObjectId objectId, int type)	Adds the id to the bitmap.
BitmapIndex.BitmapBuilder	andNot(BitmapIndex.Bitmap other)	Bitwise-AND-NOT the current bitmap with the value from the other bitmap.
BitmapIndex.Bitmap	build()
int	cardinality()
boolean	contains(AnyObjectId objectId)	Whether the bitmap has the id set.
BitmapIndex	getBitmapIndex()	Get the BitmapIndex for this BitmapBuilder.
BitmapIndex.BitmapBuilder	or(BitmapIndex.Bitmap other)	Bitwise-OR the current bitmap with the value from the other bitmap.
void	remove(AnyObjectId objectId)	Remove the id from the bitmap.
boolean	removeAllOrNone(PackBitmapIndex bitmapIndex)	Determines if the entire bitmap index is contained in the bitmap.
BitmapIndex.BitmapBuilder	xor(BitmapIndex.Bitmap other)	Bitwise-XOR the current bitmap with the value from the other bitmap.

Method Detail

contains

boolean contains(AnyObjectId objectId)

Whether the bitmap has the id set.

Parameters:

objectId - the object ID

Returns:

whether the bitmap currently contains the object ID

addObject

BitmapIndex.BitmapBuilder addObject(AnyObjectId objectId,
                                    int type)

Adds the id to the bitmap.

Parameters:

objectId - the object ID

type - the Git object type. See Constants.

Returns:

the current builder.

Since:

4.2

remove

void remove(AnyObjectId objectId)

Remove the id from the bitmap.

Parameters:

objectId - the object ID

or

BitmapIndex.BitmapBuilder or(BitmapIndex.Bitmap other)

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:

the current builder.

andNot

BitmapIndex.BitmapBuilder andNot(BitmapIndex.Bitmap other)

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:

the current builder.

xor

BitmapIndex.BitmapBuilder xor(BitmapIndex.Bitmap other)

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:

the current builder.

build

BitmapIndex.Bitmap build()

Returns:

the fully built immutable bitmap

removeAllOrNone

boolean removeAllOrNone(PackBitmapIndex bitmapIndex)

Determines if the entire bitmap index is contained in the bitmap. If it is, the matching bits are removed from the bitmap and true is returned. If the bitmap index is null, false is returned.

Parameters:

bitmapIndex - the bitmap index to check if it is completely contained inside of the current bitmap.

Returns:

true if the bitmap index was a complete match.

cardinality

int cardinality()

Returns:

the number of elements in the bitmap.

getBitmapIndex

BitmapIndex getBitmapIndex()

Get the BitmapIndex for this BitmapBuilder.

Returns:

the BitmapIndex for this BitmapBuilder

Since:

4.2
