                                     throws IOException

Deprecated.

Private utility to write the InputStream contents to the OutputStream.

Parameters:

is -

os -

Throws:

IOException

inputStream2OutputStream

public static int inputStream2OutputStream(InputStream is,
                                           OutputStream os,
                                           int limit)
                                    throws IOException

Deprecated.

Parameters:

is - InputStream

os - OutputStream

limit - maximum number of bytes to read

Returns:

total bytes read

Throws:

IOException

inputStream2FileOutputStream

public static boolean inputStream2FileOutputStream(InputStream is,
                                                   FileOutputStream fos)
                                            throws IOException

Deprecated.

Opimized writing to FileOutputStream using a channel

Parameters:

is -

fos -

Returns:

false if lock was not aquired

Throws:

IOException

inputStream2BAAOutputStream

public static long inputStream2BAAOutputStream(InputStream is,
                                               BAAOutputStream baaos,
                                               long limit)
                                        throws IOException

Deprecated.

inputStream2BAAOutputStream

Parameters:

is -

baaos -

limit -

Returns:

the number of bytes copied

Throws:

IOException

doesDataHandlerExceedLimit

public static int doesDataHandlerExceedLimit(DataHandler dh,
                                             int limit)

Deprecated.

The method checks to see if attachment is eligble for optimization. An attachment is eligible for optimization if and only if the size of the attachment is greated then the optimzation threshold size limit. if the Content represented by DataHandler has size less than the optimize threshold size, the attachment will not be eligible for optimization, instead it will be inlined.

Parameters:

dh -

limit -

Returns:

1 if DataHandler data is bigger than limit, 0 if DataHandler data is smaller or -1 if an error occurs or unsupported.
