Instance Methods

[hide private]

__init__(self, bit_len=None, blob=None)
If blob is specified, create a bit-array from it, assuming it is an sqlite blob containing packed Longs constituting a bit array.

clear(self)
Unset all bits

unset(self, jbit)
Unset a specified bit

set(self, jbit)
Set a specified bit

get(self, jbit)
Return the value of a specified bit

getList(self)
Return a Py list of the bits that are set

blobify(self)
Return a blob of the bit array suitable for inserting into sqlite

deblobify(self, blob)
Unpack an sqlite blob into a bit array

Method Details

init(self, bit_len=None, blob=None)
(Constructor)

If blob is specified, create a bit-array from it, assuming it is an sqlite blob containing packed Longs constituting a bit array. Else, if bit_len is specified, return an empty bit set large enough to hold the specified number of bits. An exception is thrown if neither neither bit_len nor blob is specified.
