public class UserDataBox
extends AbstractContainerBox

This box contains objects that declare user information about the containing box and its data (presentation or track).
The User Data Box is a container box for informative user-data. This user data is formatted as a set of boxes with more specific box types, which declare more precisely their content

Constructor Detail

UserDataBox

public UserDataBox()
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 AbstractContainerBox
Returns:
Gets the box's content size in bytes

parse

public void parse(ReadableByteChannel in,
                  ByteBuffer header,
                  long contentSize,
                  BoxParser boxParser)
           throws IOException
Description copied from class: AbstractBox
Pareses the given IsoBufferWrapper and returns the remaining bytes.

Specified by:
parse in interface Box
Overrides:
parse in class AbstractContainerBox
Parameters:
in - the (part of the) iso file to parse
contentSize - expected contentSize of the box
boxParser - creates inner boxes
Throws:
IOException - in case of an I/O error.

_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 AbstractContainerBox

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