parse

public void parse(java.nio.channels.ReadableByteChannel dataSource,
                  java.nio.ByteBuffer header,
                  long contentSize,
                  BoxParser boxParser)
           throws java.io.IOException

Description copied from interface: ParsableBox

Parses the box excluding the already parsed header (size, 4cc, [long-size], [user-type]). The remaining size of the box is the contentSize, contentSize number of bytes should be read from the box source (readableByteChannel). If you need the header buffer at a later stage you have to create a copy.

Specified by:

parse in interface ParsableBox

Overrides:

parse in class AbstractContainerBox

Parameters:

dataSource - the source for this box

header - the box' already parsed header (create copy if you need it later as it will be overwritten)

contentSize - remaining bytes of this box

boxParser - use it to parse sub-boxes.

Throws:

java.io.IOException - in case of an error during a read operation

getBox

public void getBox(java.nio.channels.WritableByteChannel writableByteChannel)
            throws java.io.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 AbstractContainerBox

Parameters:

writableByteChannel - the box's sink

Throws:

java.io.IOException - in case of problems with the Channel

getSize

public long getSize()

Specified by:

getSize in interface Box

Overrides:

getSize in class AbstractContainerBox
