Method Summary

Modifier and Type	Method and Description
static Writer	asWriter(Appendable appendable) faster variant than guava CharStreams.asWriter.
static long	copy(InputStream is, OutputStream os) see copy(final InputStream is, final OutputStream os, final int buffSize) for detail.
static long	copy(InputStream is, OutputStream os, int buffSize) Equivalent to guava ByteStreams.copy, with one special behavior: if is has no bytes immediately available for read, the os is flushed prior to the next read that will probably block.

Method Detail

copy

public static long copy(InputStream is,
                        OutputStream os)
                 throws IOException

see copy(final InputStream is, final OutputStream os, final int buffSize) for detail.

Parameters:

is -

os -

Returns:

Throws:

IOException

copy

public static long copy(InputStream is,
                        OutputStream os,
                        int buffSize)
                 throws IOException

Equivalent to guava ByteStreams.copy, with one special behavior: if is has no bytes immediately available for read, the os is flushed prior to the next read that will probably block. I believe this behavior will yield better performance in most scenarios. This method also makes use of: Arrays.getBytesTmp. THis method should not be invoked from any context making use of Arrays.getBytesTmp.

Parameters:

is -

os -

buffSize -

Throws:

IOException

asWriter

public static Writer asWriter(Appendable appendable)

faster variant than guava CharStreams.asWriter.

Parameters:

appendable - - the appendable to transform.

Returns:

- the writer that will write to the appendable.
