  de.humatic.dsj.util.Atom

public class Atom
extends java.lang.Object

Atoms are data units used in atomic file types inheriting from the original Quicktime file format (like ISO MPEG4). Atoms have size, type and data fields and may contain nested child atoms. They are read from files or raw data by AtomParsers and can not be constructed directly.

Method Summary

Atom	getChildByIndex(int idx)
byte[]	getData() Returns the Atom's raw data, which may consist of child atom's
java.lang.String	getID() Returns the Atom's four char code ID string
Atom	getNextChild(Atom currentChild) Returns the child atom following currentChild in this atom's data.
Atom	getParent()
int	getSize() Returns the Atom's data size.
int	getType() Returns the Atom's four char code as an int.
boolean	isContainer() Returns true if this is a known container atom that might contain child atoms.

Method Detail

isContainer

public boolean isContainer()

Returns true if this is a known container atom that might contain child atoms.

getParent

public Atom getParent()

getSize

public int getSize()

Returns the Atom's data size. The total size of the atom is 8 bytes larger.

getType

public int getType()

Returns the Atom's four char code as an int.

getID

public java.lang.String getID()

Returns the Atom's four char code ID string

getData

public byte[] getData()

Returns the Atom's raw data, which may consist of child atom's

getChildByIndex

public Atom getChildByIndex(int idx)

getNextChild

public Atom getNextChild(Atom currentChild)

Returns the child atom following currentChild in this atom's data. Returns the first child if %currentChild is null or null if this is not a container atom.
