Method Detail

cloneBitSet

protected BitSet cloneBitSet()

clear

public void clear()

Description copied from interface: MutableBitmap

Empties the content of this bitmap.

Specified by:

clear in interface MutableBitmap

or

public void or(MutableBitmap mutableBitmap)

Description copied from interface: MutableBitmap

Compute the bitwise-or of this bitmap with another bitmap. The current bitmap is modified whereas the other bitmap is left intact. Note that the other bitmap should be of the same class instance.

Specified by:

or in interface MutableBitmap

Parameters:

mutableBitmap - other bitmap

and

public void and(MutableBitmap mutableBitmap)

andNot

public void andNot(MutableBitmap mutableBitmap)

getSizeInBytes

public int getSizeInBytes()

Description copied from interface: MutableBitmap

Return the size in bytes for the purpose of serialization to a ByteBuffer. Note that this is distinct from the memory usage.

Specified by:

getSizeInBytes in interface MutableBitmap

Returns:

the total set in bytes

add

public void add(int entry)

Description copied from interface: MutableBitmap

Add the specified integer to the bitmap. This is equivalent to setting the ith bit to the value 1.

Specified by:

add in interface MutableBitmap

Parameters:

entry - integer to be added

remove

public void remove(int entry)

Description copied from interface: MutableBitmap

Remove the specified integer to the bitmap. This is equivalent to setting the ith bit to the value 1.

Specified by:

remove in interface MutableBitmap

Parameters:

entry - integer to be remove

serialize

public void serialize(ByteBuffer buffer)
