Each instance is created with an argument which specifies the URL of

A Package can be initialized with one of the following:

1. A file URL referring to a package.

2. An XInputStream referring to a package (it must also

support an XSeekable interface).

3. An XStream referring to a package. The XInputStream must support

an XSeekable interface, and the XOutputStream must support an

XTruncate interface.

This interface is used to create new PackageStream or PackageFolder

implementation objects for addition to the Package.

|
|
createInstance - creates a new stream implementation object (when first
|
|
created, the new object is not part of the Package). It must be added
|
|
to the PackageFolder in which it will reside using the methods in the
|
|
PackageFolder service.

createInstanceWithArguments - This accepts one boolean value as an

argument. If it set to true, a PackageFolder implementation is created,

if it is set to false, a PackageStream implementation is created.

Creating and inserting a new stream would be done as follows:
|
|
|
|
1. xNewStream = package->createInstanceWithArguments( false );

2. xDataStream = new MyStreamImpl(). (wherever the data comes from)

3. xNewStream->setInputStream( xDataStream );

4. parentFolder->insertByName( "image.png", xNewStream );

Replacing an existing stream would be very similar, except that the
|
|
call ->insertByName would be replaced by ->replaceByName.
