Constructor Detail

Fingerprint

public Fingerprint(int numbits)
            throws DaylightException
Allocate a new fingerprint. Allocates a new, empty fingerprint. The fingerprint's size will be set to the value of 'size'. Legal values of 'size' are 32 to 1073741824 (2^30). If not a power of two, 'size' will be rounded to the next highest power of two. The object initially has no bits set (all bits are zero). Note that a 1Gbit fingerprint consumes significant system memory (128MB).

Throws:
DaylightException
Method Detail

copy

public Fingerprint copy()
                 throws DaylightException

from dt_fp_commonbitcount.

Throws:
DaylightException

getSize

public int getSize()
            throws DaylightException
from dt_fp_nbits. Returns fingerprint size in bits.

Throws:
DaylightException

getBitValue

public int getBitValue(int bitNumber)
                throws DaylightException
from dt_fp_bitvalue.
