Method Detail

clear

void clear()

Empties the content of this bitmap.

or

void or(MutableBitmap 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.

Parameters:

mutableBitmap - other bitmap

getSizeInBytes

int getSizeInBytes()

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

Returns:

the total set in bytes

add

void add(int entry)

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

Parameters:

entry - integer to be added

remove

void remove(int entry)

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

Parameters:

entry - integer to be remove
