All Implemented Interfaces:
Box, ContainerBox, FullBox

public class DataReferenceBox
extends FullContainerBox

The data reference object contains a table of data references (normally URLs) that declare the location(s) of the media data used within the presentation. The data reference index in the sample description ties entries in this table to the samples in the track. A track may be split over several sources in this way. If the flag is set indicating that the data is in the same file as this box, then no string (not even an empty one) shall be supplied in the entry field. The DataEntryBox within the DataReferenceBox shall be either a DataEntryUrnBox or a DataEntryUrlBox.

DataReferenceBox

public DataReferenceBox()
Method Detail

getContentSize

protected long getContentSize()
Description copied from class: AbstractBox
Gets the box's content size. This excludes all header fields:

Flags and version of a full box need to be taken into account.

Overrides:
getContentSize in class FullContainerBox
Returns:
Gets the box's content size in bytes

_parseDetails

public void _parseDetails(ByteBuffer content)
Description copied from class: AbstractBox
Implement the actual parsing of the box's fields here. External classes will always call AbstractBox.parseDetails() which encapsulates the call to this method with some safeguards.

Overrides:
_parseDetails in class FullContainerBox

getContent

protected void getContent(ByteBuffer bb)
                   throws IOException
Description copied from class: AbstractBox
Writes the box's content into the given ByteBuffer. This must include flags and version in case of a full box. bb has been initialized with getSize() bytes.

Overrides:
getContent in class FullContainerBox
Parameters:
bb - the box's content-sink.
Throws:
IOException - in case of an exception in the underlying OutputStream.
