bx.misc.binary_file module

Wrappers for doing binary IO on file-like objects

exception bx.misc.binary_file.BadMagicNumber

Bases: OSError

class bx.misc.binary_file.BinaryFileReader(file, magic=None, is_little_endian=False)

Bases: object

Wrapper for doing binary reads on any file like object.

Currently this is not heavily optimized (it uses the struct module to unpack)

read(byte_count=1)

read_and_unpack(format, byte_count=None)

Read enough bytes to unpack according to format and return the tuple of unpacked values.

read_c_string()

Read a zero terminated (C style) string

read_float()

read_raw_array(dtype, size)

read_uint16()

read_uint32()

read_uint64()

read_uint8()

seek(pos, whence=0)

skip(count)

tell()

unpack(format, buffer, byte_count=None)

class bx.misc.binary_file.BinaryFileWriter(file, magic=None, is_little_endian=False)

Bases: object

Wrapper for doing binary writes on any file like object.

Currently this is not heavily optimized (it uses the struct module to unpack)

pack(format, buffer)

pack_and_write(format, value)

Read enough bytes to unpack according to format and return the tuple of unpacked values.

seek(pos, whence=0)

skip(count)

tell()

write(value)

write_c_string(value)

Read a zero terminated (C style) string

write_raw_array(value)

write_uint16(value)

write_uint32(value)

write_uint64(value)

write_uint8(value)
