Free outputstream software for linux

Servlet::ServletOutputStream is a servlet output stream interface.

SYNOPSIS

$stream->print($string);

$stream->println();
$stream->println($string);

$stream->write($string);
$stream->write($string, $length);
$stream->write($string, $length, $offset);

$stream->flush();

$stream->close();

Provides an output stream for writing binary data to a servlet response.
An output stream object is normally retrieved via "getOutputStream" in Servlet::ServletResponse.

NOTE: While this is an abstract class in the Java API, the Perl API provides it as an interface. The main difference is that the Perl version has no constructor. Also, it merges the methods declared in java.io.OutputStream and javax.servlet.ServletOutputStream into a single interface.

METHODS

close()

Closes the stream and releases any system resources associated with the stream.

Throws:

Servlet::Util::IOException

if an output exception occurred

flush()

Flushes this input stream and forces any buffered output bytes to be written out.

Throws:

Servlet::Util::IOException

if an output exception occurred

print($value)

Writes a scalar value to the client, with no carriage return-line feed (CRLF) character at the end.

Parameters:

$value

the value to send to the client

Throws:

Servlet::Util::IOException

if an output exception occurred

println([$value])

Writes a scalar value to the client, if specified, followed by a carriage return-line feed (CRLF) character.

Parameters:

$value

the (optional) value to send to the client

Throws:

Servlet::Util::IOException

if an output exception occurred

write($value)

write($value, $length)

write($value, $length, $offset)

Writes the scalar $value to the stream.

If no arguments are specified, functions exactly equivalently to print().

If $length is specified, writes that many bytes from $value. If $offset is specified, starts writing that many bytes from the beginning of $value. $offset and $length must not be negative, and $length must not be greater than the amount of data in $value starting from $offset.

Blocks until input data is available, the end of the stream is detected, or an exception is thrown.

Parameters:

$value

a scalar value to be written

$length

the maximum number of bytes to write

$offset

the location in $value where data is read from

Throws:

Servlet::Util::IOException

if an input exception occurs

Servlet::Util::IndexOutOfBoundsException

if $buffer is specified as undef

UnifiedIO is a Java library providing random access to any data stream (even over HTTP), and giving a clear differentiation between read only and read/write access. Unified I/O is an open source project and is licensed under BSD.
Main features:
- High performance
- Transparent buffering
- MemoryManager
- (Open)FileManager (beta)
- uio based implementation of ImageInputStream and ImageOutputStream
- Bridge between RandomAccessFile world and InputStream/OutputStream world
- Access everything using one common interface
- Read/write direct from/into primitive arrays
- Optimized reading over http (only requesting the required data range of bytes - uses Byteserving feature of http 1.1)
- Easy extensible design
- Unified I/O contains also many utilities:
- BitInputStream and BitOutputStream.
- PackBits, RLE4 and RLE8 decoder.
- base64 codec implementation.
- and many others.
