Throws:

NullPointerException - if mime == null

getRenditions

public ItemsIterator<Rendition> getRenditions(ObjectData object)

Get all renditions of specified entry.

Parameters:

object - object for getting renditions

                                        MimeType mime)
                                 throws IOException

Returns:

rendition content stream or null if there is no RenditionProvider which can produce stream for requested type

                                 throws IOException

Get rendition stream for objects with specified stream id.

Parameters:

streamId - stream id

obj - ObjectData
