NAME Data::BinaryBuffer - The module to work with binary data effectively VERSION version 0.003 SYNOPSIS use Data::BinaryBuffer; my $buf = Data::BinaryBuffer->new; $buf->write($some_data); # PSD file for ex my $sig = $buf->read(4); die "This is not PSD file" if $sig ne '8BPS'; my $version = $buf->read_uint16be; # etc... DESCRIPTION NOTE: This module is in very alpha state. API may change without any notice until version 0.1. Perl is good for strings, bug not very nice to binary data. This class exactly for that. Data::BinaryBuffer is a data structure similar to the queue, but optimized to work with blocks of arbitrary size. You can write data to one end of buffer and read from another. Data can be written or read in various formats. METHODS new my $buf = Data::BinaryBuffer->new; Creates empty buffer object. size my $size = $buf->size; Returns current amount of bytes stored in buffer. write $buf->write($data); Write scalar to the buffer. write_uint8 write_uint16be write_uint16le write_uint32be write_uint32le write_int8 write_int16be write_int16le write_int32be write_int32le $buf->write_uint8(255); $buf->write_int32be($value); Write one integer to the buffer. read my $data = $read($size); Read $size bytes to Perl scalar. read_uint8 read_uint16be read_uint16le read_uint32be read_uint32le read_int8 read_int16be read_int16le read_int32be read_int32le my $num1 = $buf->read_uint32be; Read integer from buffer. read_buffer my $buf2 = $buf->read_buffer($size); Same as "read", but return another buffer. This method is very fast for big data.
