Constructor Details

MediaPackageReferenceImpl

public MediaPackageReferenceImpl()

Creates a reference to the containing media package (self).

MediaPackageReferenceImpl

public MediaPackageReferenceImpl(MediaPackage mediaPackage)

Creates a reference to the specified media package.

Parameters:

mediaPackage - the media package to refer to

MediaPackageReferenceImpl

public MediaPackageReferenceImpl(MediaPackageElement mediaPackageElement)

Creates a reference to the specified media package element.

Note that the referenced element must already be part of the media package, otherwise a MediaPackageException will be thrown as the object holding this reference is added to the media package.

Parameters:

mediaPackageElement - the media package element to refer to

MediaPackageReferenceImpl

public MediaPackageReferenceImpl(String type,
 String identifier)

Creates a reference to the entity identified by type and identifier.

Parameters:

type - the reference type

identifier - the reference identifier

Method Details

fromString

public static MediaPackageReference fromString(String reference)
                                        throws IllegalArgumentException

Returns a media package reference from the given string.

Returns:

the media package reference

Throws:

IllegalArgumentException - if the string is malformed

getIdentifier

public String getIdentifier()

Description copied from interface: MediaPackageReference

Returns the reference identifier.

The identifier will usually refer to the id of the media package element, should the reference point to an element inside the media package (see MediaPackageElement.getIdentifier()).

In case of a reference to another media package, this will reflect the media package id (see MediaPackage.getIdentifier()) or self if it refers to the parent media package.

Specified by:

getIdentifier in interface MediaPackageReference

Returns:

the reference identifier

See Also:

• MediaPackageReference.getIdentifier()

getType

public String getType()

Description copied from interface: MediaPackageReference

Returns the reference type.

There is a list of well known types describing media package elements:

• mediapackage a reference to the parent media package
• track referes to a track inside the media package
• catalog referes to a catalog inside the media package
• attachment referes to an attachment inside the media package
• series referes to a series

Specified by:

getType in interface MediaPackageReference

Returns:

the reference type

See Also:

• MediaPackageReference.getType()

getProperties

public Map<String,String> getProperties()

Description copied from interface: MediaPackageReference

Returns additional properties that further define what the object is referencing.

An example would be the point in time for a slide preview:

  <attachment ref="track:track-7;time=8764">
  </attachment>
 

Specified by:

getProperties in interface MediaPackageReference

Returns:

the properties
