_parseDetails

public void _parseDetails(ByteBuffer content)

Description copied from class: AbstractBox

Parse the box's fields and child boxes if any.

Specified by:

_parseDetails in class AbstractBox

Parameters:

content - the box's raw content beginning after the 4-cc field.

getEntries

public List<CencSampleAuxiliaryDataFormat> getEntries()

setEntries

public void setEntries(List<CencSampleAuxiliaryDataFormat> entries)

getContent

protected void getContent(ByteBuffer byteBuffer)

Description copied from class: AbstractBox

Write the box's content into the given ByteBuffer. This must include flags and version in case of a full box. byteBuffer has been initialized with getSize() bytes.

Specified by:

getContent in class AbstractBox

Parameters:

byteBuffer - the sink for the box's content

getContentSize

protected long getContentSize()

Description copied from class: AbstractBox

Get the box's content size without its header. This must be the exact number of bytes that getContent(ByteBuffer) writes.

Specified by:

getContentSize in class AbstractBox

Returns:

Gets the box's content size in bytes

getBox

public void getBox(WritableByteChannel os)
            throws IOException

Description copied from interface: Box

Writes the complete box - size | 4-cc | content - to the given writableByteChannel.

Specified by:

getBox in interface Box

Overrides:

getBox in class AbstractBox

Parameters:

os - the box's sink

Throws:

IOException - in case of problems with the Channel

equals

public boolean equals(Object o)

Overrides:

equals in class Object
