Package cpyamf :: Module util :: Class cBufferedByteStream

Class cBufferedByteStream

A file like object that can be read/written to. Supports data type specific reads/writes (e.g. ints, longs, floats etc.)

Endian aware.

Instance Methods

new(T, S, ...)

Returns: a new object with type S, a subtype of T
Overrides: object.__new__

consume(...)

Chops the tail off the stream starting at 0 and ending at tell(). The stream pointer is set to 0 at the end of this function.

seek(...)

Sets the file-pointer offset, measured from the beginning of this stream, at which the next write operation will occur.

Parameters:

mode - mode 0: absolute; 1: relative; 2: relative to EOF

truncate(...)

Truncates the stream to the specified length.

Parameters:

size (int) - The length of the stream, in bytes.

write_24bit_int(...)

Writes a 24 bit integer to the stream.

Parameters:

ret (int) - 24 bit integer

write_24bit_uint(...)

Writes a 24 bit unsigned integer to the stream.

Parameters:

ret (int) - 24 bit unsigned integer

write_char(...)

Write a char to the stream.

Parameters:

ret (int) - char

write_double(...)

Writes an 8 byte float to the stream.

Parameters:

val (float) - 8 byte float

write_float(...)

Writes a 4 byte float to the stream.

Parameters:

c (float) - 4 byte float

write_long(...)

Writes a 4 byte integer to the stream.

Parameters:

ret (int) - 4 byte integer

write_short(...)

Writes a 2 byte integer to the stream.

Parameters:

ret (int) - 2 byte integer

write_uchar(...)

Writes an unsigned char to the stream.

Parameters:

ret (int) - Unsigned char

write_ulong(...)

Writes a 4 byte unsigned integer to the stream.

Parameters:

ret (int) - 4 byte unsigned integer

write_ushort(...)

Writes a 2 byte unsigned integer to the stream.

Parameters:

ret (int) - 2 byte unsigned integer

write_utf8_string(...)

Writes a unicode object to the stream in UTF-8.

Parameters:

obj - unicode object

Raises:

TypeError - Unexpected type for str u.
