public void parse(ReadableByteChannel readableByteChannel,
                  ByteBuffer header,
                  long contentSize,
                  BoxParser boxParser)
           throws IOException

Description copied from class: AbstractBox

Read the box's content from a byte channel without parsing it. Parsing is done on-demand.

Specified by:

parse in interface Box

Overrides:

parse in class AbstractContainerBox

Parameters:

readableByteChannel - 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

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

Overrides:

_parseDetails in class AbstractContainerBox

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

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.

Overrides:

getContent in class AbstractContainerBox

Parameters:

byteBuffer - the sink for the box's content
