class ida_bitrange.bitrange_t(bit_ofs: uint16 = 0, size_in_bits: uint16 = 0)

Bases: object

thisown

init(bit_ofs: uint16, size_in_bits: uint16) → None: Initialize offset and size to given values.

reset() → None: Make the bitrange empty.

empty() → bool: Is the bitrange empty?

bitoff() → uint: Get offset of 1st bit.

bitsize() → uint: Get size of the value in bits.

bytesize() → uint: Size of the value in bytes.

mask64() → uint64: Convert to mask of 64 bits.

has_common(r: bitrange_t) → bool: Does have common bits with another bitrange?

apply_mask(subrange: bitrange_t) → bool

Apply mask to a bitrange

Parameters:: subrange – range inside the main bitrange to keep After this operation the main bitrange will be truncated to have only the bits that are specified by subrange. Example: [off=8,nbits=4], subrange[off=1,nbits=2] => [off=9,nbits=2]
Returns:: success

intersect(r: bitrange_t) → None: Intersect two ranges.

create_union(r: bitrange_t) → None: Create union of 2 ranges including the hole between them.

sub(r: bitrange_t) → bool: Subtract a bitrange.

shift_down(cnt: uint) → None: Shift range down (left)

shift_up(cnt: uint) → None: Shift range up (right)

extract(src: void const *, is_mf: bool) → bool

inject(dst: void *, src: bytevec_t const &, is_mf: bool) → bool

compare(r: bitrange_t) → int
