- <div class="block">This class provides static utility methods for buffered
- copying between sources (<code>InputStream</code>, <code>Reader</code>,
- <code>String</code> and <code>byte[]</code>) and destinations
- (<code>OutputStream</code>, <code>Writer</code>, <code>String</code> and
- <code>byte[]</code>).
- <p>
- Unless otherwise noted, these <code>copy</code> methods do <em>not</em>
- flush or close the streams. Often doing so would require making non-portable
- assumptions about the streams' origin and further use. This means that both
- streams' <code>close()</code> methods must be called after copying. if one
- omits this step, then the stream resources (sockets, file descriptors) are
- released when the associated Stream is garbage-collected. It is not a good
- idea to rely on this mechanism. For a good overview of the distinction
- between "memory management" and "resource management", see
- <a href="http://www.unixreview.com/articles/1998/9804/9804ja/ja.htm">this
- UnixReview article</a>.
- <p>
- For byte-to-char methods, a <code>copy</code> variant allows the encoding
- to be selected (otherwise the platform default is used). We would like to
- encourage you to always specify the encoding because relying on the platform
- default can lead to unexpected results.
- <p>
- We don't provide special variants for the <code>copy</code> methods that
- let you specify the buffer size because in modern VMs the impact on speed
- seems to be minimal. We're using a default buffer size of 4 KB.
- <p>
- The <code>copy</code> methods use an internal buffer when copying. It is
- therefore advisable <em>not</em> to deliberately wrap the stream arguments
- to the <code>copy</code> methods in <code>Buffered*</code> streams. For
- example, don't do the following:
- <pre>
- copy( new BufferedInputStream( in ), new BufferedOutputStream( out ) );
- </pre>
- The rationale is as follows:
- <p>
- Imagine that an InputStream's read() is a very expensive operation, which
- would usually suggest wrapping in a BufferedInputStream. The
- BufferedInputStream works by issuing infrequent
- <a href="http://docs.oracle.com/javase/7/docs/api/java/io/InputStream.html?is-external=true#read-byte:A-int-int-" title="class or interface in java.io"><code>InputStream.read(byte[] b, int off, int len)</code></a> requests on the
- underlying InputStream, to fill an internal buffer, from which further
- <code>read</code> requests can inexpensively get their data (until the buffer
- runs out).
- <p>
- However, the <code>copy</code> methods do the same thing, keeping an
- internal buffer, populated by
- <a href="http://docs.oracle.com/javase/7/docs/api/java/io/InputStream.html?is-external=true#read-byte:A-int-int-" title="class or interface in java.io"><code>InputStream.read(byte[] b, int off, int len)</code></a> requests. Having two
- buffers (or three if the destination stream is also buffered) is pointless,
- and the unnecessary buffer management hurts performance slightly (about 3%,
- according to some simple experiments).
- <p>
- Behold, intrepid explorers; a map of this class:
- <pre>
- Method Input Output Dependency
- ------ ----- ------ -------
- 1 copy InputStream OutputStream (primitive)
- 2 copy Reader Writer (primitive)
- 3 copy InputStream Writer 2
- 4 copy Reader OutputStream 2
- 5 copy String OutputStream 2
- 6 copy String Writer (trivial)
- 7 copy byte[] Writer 3
- 8 copy byte[] OutputStream (trivial)
- </pre>
- <p>
- Note that only the first two methods shuffle bytes; the rest use these
- two, or (if possible) copy using native Java copy methods. As there are
- method variants to specify the encoding, each row may
- correspond to up to 2 methods.
