Method Detail

createFile

public static java.io.File createFile(java.io.InputStream input,
                                      int expected)
                               throws java.io.IOException

Read from the inputstream associated with the socket and write the data straight out to a unique file in the temporary (system defined) directory

Parameters:

input - The inputstream to read from

expected - the expected number of bytes

Returns:

a File object corresponding to the temporary file that was created

Throws:

java.io.IOException - if there was an error creating the file

createFile

public static java.io.File createFile(java.io.InputStream input,
                                      int expected,
                                      java.lang.String dir)
                               throws java.io.IOException

Read from the inputstream associated with the socket and write the data straight out to a unique file in the specified directory

Parameters:

input - The inputstream to read from

expected - the expected number of bytes

dir - The directory in which to create the file

Returns:

a File object corresponding to the temporary file that was created

Throws:

java.io.IOException - if there was an creating the file

copyStream

public static void copyStream(java.io.InputStream input,
                              java.io.OutputStream output,
                              int expected)
                       throws java.io.IOException

Copy from an InputStream to an OutputStream for expected bytes.

Parameters:

input - the input stream to read from

output - the output stream to write from

expected - the number of bytes to copy

Throws:

java.io.IOException - if there was an error.

copyStream

public static void copyStream(java.io.InputStream input,
                              java.io.OutputStream output)
                       throws java.io.IOException

Copy from an InputStream to an OutputStream for expected bytes.

Parameters:

input - the input stream to read from

output - the output stream to write from

Throws:

java.io.IOException - if there was an IO error

makeCopy

public static java.io.InputStream makeCopy(java.io.InputStream input)
                                    throws java.io.IOException

Make a copy of an InputStream.

This method ensures that the resulting input stream can support a mark(), and reset() call, by copying the contents of the input stream into a ByteArrayInputStream

Parameters:

input - the InputStream to copy

Returns:

a copy of the input stream

Throws:

java.io.IOException - if there was an error reading the stream.

copyAndClose

public static void copyAndClose(java.io.InputStream input,
                                java.io.Writer out)

Throws:

java.io.IOException

public static void copyAndClose(java.io.InputStream input,
                                java.io.Writer out,
                                java.nio.charset.Charset charset)
                         throws java.io.IOException

Throws:

java.io.IOException

copyAndClose

public static void copyAndClose(java.io.InputStream input,
