Method Detail

handleMetadata

protected MediaMetadata handleMetadata(MediaRequest request,
                                       org.springframework.core.io.Resource mediaResource,
                                       MediaItem item)

Description copied from class: AbstractMediaHandler

Extract metadata from a resource and replace item metadata with all extracted data.

This method provides a simple way to populate the Metadata list of a newly created MediaItem. It will generate the list of Metadata and then add all of them into the List returned by MediaItem.getMetadata().

This method first calls AbstractMediaHandler.getMediaMetadataInstance(MediaRequest, Resource, MediaItem) to create a new instance of MediaMetadata and then calls MediaMetadata.setMediaResource(Resource).

If MediaMetadata.getCreationDate() returns a non-null value then a new Calendar instance will be created from it and used to set the creationDate property of the MediaItem.

If the MediaMetadata is an instance of EmbeddedImageMetadata then EmbeddedImageMetadata.getEmbeddedImage() will be called, and the width/height of the returned image will be used to set the width/height properties of the MediaItem provided.

Overrides:

handleMetadata in class AbstractMediaHandler

Parameters:

request - the reqeust (may be null)

mediaResource - the media resource to extract the metadata from

item - the item to replace the extracted metadata in

Returns:

the resulting metadata instance

getSongTitleMetaKey

public java.lang.String getSongTitleMetaKey()

Returns:

the songTitleMetaKey

setSongTitleMetaKey

public void setSongTitleMetaKey(java.lang.String songTitleMetaKey)

Parameters:

songTitleMetaKey - the songTitleMetaKey to set
