Method Detail

getExhibitType

public ExhibitMIME.ExhibitTypeParameters getExhibitType()

Get internal type of ExhibitMIME type; never null.

getSequence

protected javax.sound.midi.Sequence getSequence(java.io.InputStream is)

Get format of audio data; null if none or format not usable/parseable. This may require the stream to be seekable, at least with mark() and reset().

getMetadata

public org.w3c.dom.Node getMetadata(java.io.InputStream is,
                                    Name.ExhibitFull exhibitName)

Gets all available exhibit metadata as a single XML DOM tree; null if none. We do not (yet) have a schema for this and may never do so, since its structure and content will depend on various external sources and parts of (for example) the ImageIO and JAI subsystems.

This implementation synthesises a metadata tree from the AudioFileFormat data, if any.

Specified by:: getMetadata in interface Handler
Overrides:: getMetadata in class AbstractHandler

Parameters:: is - input stream; never null; exhibitName - TODO
Returns:: top-level node "metadata" with captured metadata beneath, else null
