CompressedBitmapBuilder

CompressedBitmapBuilder(BitmapIndexImpl bitmapIndex)

Method Detail

contains

public boolean contains(AnyObjectId objectId)

Description copied from interface: BitmapIndex.BitmapBuilder

Whether the bitmap has the id set.

Specified by:

contains in interface BitmapIndex.BitmapBuilder

Parameters:

objectId - the object ID

Returns:

whether the bitmap currently contains the object ID

addObject

public BitmapIndex.BitmapBuilder addObject(AnyObjectId objectId,
                                           int type)

Description copied from interface: BitmapIndex.BitmapBuilder

Adds the id to the bitmap.

Specified by:

addObject in interface BitmapIndex.BitmapBuilder

Parameters:

objectId - the object ID

type - the Git object type. See Constants.

Returns:

the current builder.

remove

public void remove(AnyObjectId objectId)

Description copied from interface: BitmapIndex.BitmapBuilder

Remove the id from the bitmap.

Specified by:

remove in interface BitmapIndex.BitmapBuilder

Parameters:

objectId - the object ID

or

public BitmapIndexImpl.CompressedBitmapBuilder or(BitmapIndex.Bitmap other)

Description copied from interface: BitmapIndex.BitmapBuilder

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

Specified by:

or in interface BitmapIndex.Bitmap

Specified by:

or in interface BitmapIndex.BitmapBuilder

Parameters:

other - the other bitmap

Returns:

the current builder.

andNot

public BitmapIndexImpl.CompressedBitmapBuilder andNot(BitmapIndex.Bitmap other)

Description copied from interface: BitmapIndex.BitmapBuilder

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

Specified by:

andNot in interface BitmapIndex.Bitmap

Specified by:

andNot in interface BitmapIndex.BitmapBuilder

Parameters:

other - the other bitmap

Returns:

the current builder.

xor

public BitmapIndexImpl.CompressedBitmapBuilder xor(BitmapIndex.Bitmap other)

Description copied from interface: BitmapIndex.BitmapBuilder

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

Specified by:

xor in interface BitmapIndex.Bitmap

Specified by:

xor in interface BitmapIndex.BitmapBuilder

Parameters:

other - the other bitmap

Returns:

the current builder.

build

public BitmapIndexImpl.CompressedBitmap build()

Specified by:

build in interface BitmapIndex.BitmapBuilder

Returns:

the fully built immutable bitmap

iterator

public java.util.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 java.lang.Iterable<BitmapObject>

Returns:

an Iterator.

cardinality

public int cardinality()

Specified by:

cardinality in interface BitmapIndex.BitmapBuilder

Returns:

the number of elements in the bitmap.

removeAllOrNone

public boolean removeAllOrNone(PackBitmapIndex index)

Description copied from interface: BitmapIndex.BitmapBuilder

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.

Specified by:

removeAllOrNone in interface BitmapIndex.BitmapBuilder

Parameters:

index - 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.

getBitmapIndex

public BitmapIndexImpl getBitmapIndex()

Description copied from interface: BitmapIndex.BitmapBuilder

Get the BitmapIndex for this BitmapBuilder.

Specified by:

getBitmapIndex in interface BitmapIndex.BitmapBuilder

Returns:

the BitmapIndex for this BitmapBuilder

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

ewahBitmap

private com.googlecode.javaewah.EWAHCompressedBitmap ewahBitmap(BitmapIndex.Bitmap other)
