Method Detail

readOnce

public java.io.InputStream readOnce()
                             throws java.io.IOException

Deprecated.

Description copied from interface: DataHandlerExt

Get an InputStream that consumes the content of this data handler. This method is similar to DataHandler.getInputStream() except that it can be invoked only once. If the content has not been buffered yet, then the implementation may choose to enable streaming of the content.

The implementation ensures that after the returned input steam is consumed, the data handler will be in the same state as after a call to DataHandlerExt.purgeDataSource().

Specified by:

readOnce in interface DataHandlerExt

Returns:

the stream representing the content; never null

Throws:

java.io.IOException - if an error occurs

deleteWhenReadOnce

public void deleteWhenReadOnce()
                        throws java.io.IOException

Deprecated.

Specified by:

deleteWhenReadOnce in interface DataHandlerExt

Throws:

java.io.IOException

purgeDataSource

public void purgeDataSource()
                     throws java.io.IOException

Deprecated.

Description copied from interface: DataHandlerExt

This method will give users an option to trigger a purge on temporary attachment files. Temp files are created for attachment data that is greater than a threshold limit. On client side These temp attachment files are not deleted untilthe virtual machine exits as user can choose to read this dataHandler. So if user is not going to use the data handlers provided on this temproray files they can choose to purge the file.

Specified by:

purgeDataSource in interface DataHandlerExt

Throws:

java.io.IOException

update

public void update(java.util.Observable o,
                   java.lang.Object arg)

Deprecated.

Specified by:

getFile

private java.io.File getFile()

Deprecated.
