Stream::Buffered - Temporary buffer to save bytes


use Stream::Buffered;

my $buf = Stream::Buffered.new($length);

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

Creates instance.

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.
