Stream::Buffered - Temporary buffer to save bytes
use Stream::Buffered; my $buf = Stream::Buffered.new($length); $buf.print("foo"); my Int $size = $buf.size; my IO::Handle $io = $buf.rewind;
Stream::Buffered is a buffer class to store arbitrary length of byte strings and then get a seekable IO::Handle once everything is buffered. It uses Blob and temporary file to save the buffer depending on the length of the size.
This library is a perl6 port of perl5's Stream::Buffered.
new(Int $length, Int $maxMemoryBufferSize = 1024 * 1024) returns Stream::Buffered
When you specify negative value as
$maxMemoryBufferSize, Stream::Buffered always uses Blob as buffer. Or when you specify 0 as
$maxMemoryBufferSize, Stream::Buffered always uses temporary file as buffer.
If you pass 0 to the first argument, Stream::Buffered decides what kind of buffer type (Blob or temp file) to use automatically.
print(Stream::Buffered:D: *@text) returns Bool
Append text to buffer.
size(Stream::Buffered:D:) returns Int
Return the size of buffer.
rewind(Stream::Buffered:D:) returns IO::Handle
Seek to the head of buffer and return buffer.
