Class DataReferenceBox
java.lang.Object
com.coremedia.iso.boxes.AbstractBox
com.coremedia.iso.boxes.AbstractFullBox
com.coremedia.iso.boxes.FullContainerBox
com.coremedia.iso.boxes.DataReferenceBox
- 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.

TYPE
public static final String TYPE

- Constant Field Values
DataReferenceBox
public DataReferenceBox()
getContentSize
protected long getContentSize()
- Description copied from class:
AbstractBox
- Gets the box's content size. This excludes all header fields:
- 4 byte size
- 4 byte type
- (large length - 8 bytes)
- (user type - 16 bytes)
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
.
