Method Detail

copy

public static void copy(java.io.InputStream is,
                        java.io.OutputStream os)
                 throws java.io.IOException

Copies the InputStream to the OutputStream using a 4k buffer.

Parameters:

is -

os -

Throws:

java.io.IOException

copy

public static void copy(java.io.InputStream is,
                        java.io.OutputStream os,
                        int size)
                 throws java.io.IOException

Copies the InputStream to the OutputStream using a defined buffer size in bytes.

Parameters:

is -

os -

size -

Throws:

java.io.IOException

copy

public static void copy(java.io.Reader in,
                        java.io.Writer out)
                 throws java.io.IOException

Copies a Reader to a Writer with an 4096 char buffer.

Parameters:

in -

out -

Throws:

java.io.IOException

copy

public static void copy(java.io.Reader in,
                        java.io.Writer out,
                        int size)
                 throws java.io.IOException

Copies a Reader to a Writer with a buffer of size characters.

Parameters:

in -

out -

size -

Throws:

java.io.IOException

fill

public static int fill(byte[] buffer,
                       java.io.InputStream is)
                throws java.io.IOException

Reads data from the InputStream and tries to fill the buffer. This may take several reads from the stream depending on the underlying stream implementation. In general the buffer will be filled unless the end of the stream is encountered.

Parameters:

buffer -

is -

Returns:

Throws:

java.io.IOException

getPartitionedInputStream

public static java.io.InputStream getPartitionedInputStream(java.io.InputStream is,
                                                            int len)

Returns an InputStream that is a partition of another InputStream. This partition must have a specified size. It is assumed that this substream will be read and closed before a new substream is started or before the original stream is read from again.

Parameters:

is -

len -

Returns:

toString

public static java.lang.String toString(java.io.InputStream is,
                                        java.lang.String encoding)

Returns a string representation of this input stream.

Parameters:

is -

Returns:
