• getPathSeparator

  public String getPathSeparator()

  Description copied from class: DefaultDataNode

  Returns a default separator string.

  Overrides:

  getNodeTLA in class DefaultDataNode

  Returns:

  "..."

• getNodeType

  public String getNodeType()

  Description copied from interface: DataNode

  Returns a short sentence indicating what kind of node this is. The return value should be just a few words. As a rough guideline it should indicate what the implementing class is.

  Specified by:

  getNodeType in interface DataNode

  Overrides:

  getNodeType in class DefaultDataNode

  Returns:

  a short description of the type of this DataNode

• allowsChildren

  public boolean allowsChildren()

  Description copied from class: DefaultDataNode

  The DefaultDataNode implementation of this method returns false.

  Specified by:

  allowsChildren in interface DataNode

  Overrides:

  allowsChildren in class DefaultDataNode

  Returns:

  true if the node is of a type which can have child nodes, false otherwise

• getChildIterator

  public Iterator getChildIterator()

  Description copied from class: DefaultDataNode

  The DefaultDataNode implementation of this method throws UnsupportedOperationException (DefaultDataNode.allowsChildren() is false).

  Specified by:

  getChildIterator in interface DataNode

  Overrides:

  getChildIterator in class DefaultDataNode

  Returns:

  an Iterator over the children. Each object iterated over should be a DataNode. Behaviour is undefined if this method is called on an object for which allowsChildren returns false.

• getEntriesAtLevel

  protected List getEntriesAtLevel(String level) throws IOException

  Returns a list of all the entries in this archive whose name starts with a given string.

  Parameters:

  level - the required prefix

• isMagic

  public static boolean isMagic(byte[] magic)

  Indicates whether the given bytes look like the start of a tar archive.

  Parameters:
