public static final String TYPE
- See Also:
- Constant Field Values
MetaBox
public MetaBox()

public long getContentSize()
- Description copied from class:
AbstractBox
- Gets the box's content size. This excludes all header fields:

- Description copied from class:
AbstractContainerBox
- The number of bytes from box start (first length byte) to the
first length byte of the first child box
- Specified by:
getNumOfBytesToFirstChild
in interface ContainerBox
- Overrides:
getNumOfBytesToFirstChild
in class AbstractContainerBox
- Returns:
- offset to first child box
_parseDetails
public void _parseDetails(ByteBuffer content)
- Description copied from class:
AbstractBox
