Parameters

session

overwrite

share

sourceFileHint

openPhysicalStreamOnly

outputStream

compressionMethod

compressionLevel

encryptionPassword

Return Value

The returned stream should be guaranteed to be writable, but does not have to be seekable.

The share parameter should allow control over how the file is shared by different processes. If the values defined in this enumeration are not supported, an exception should be thrown.

If the File implementation does not support appending or overwriting, an exception should be thrown.

If there is no existing data, the parameter overwrite should be ignored.
