  • Constructor Details

    • ZipFileDataNode

      public ZipFileDataNode(File file) throws NoSuchDataException
      Initialises a ZipFileDataNode from a File object.
      Parameters:
      file - a File object representing the file from which the node is to be created
      Throws:
      NoSuchDataException

  • Method Details

    • getParentObject

      public Object getParentObject()
      Description copied from interface: DataNode
      Returns an object which is in some sense the parent of the one this node is based on. The parent is not a DataNode, it is something which may get fed to a DataNodeFactory to create DataNode. If no such object exists, which may well be the case, null should be returned.
      Specified by:
      getParentObject in interface DataNode
      Overrides:
      getParentObject in class DefaultDataNode
      Returns:
      an object which is the parent of this one, or null

    • getEntries

      protected List getEntries() throws IOException
      Description copied from class: ZipArchiveDataNode
      Returns a list of all the ZipEntry objects in this zip archive.
      Specified by:
      getEntries in class ZipArchiveDataNode
      Returns:
      a List of all the ZipEntry objects which make up this zip archive.
      Throws:
      IOException

    • getChildIteratorAtLevel

      protected Iterator getChildIteratorAtLevel(String level, DataNode parent) throws IOException
      Description copied from class: ZipArchiveDataNode
      Returns an iterator over the DataNodes at a given level in the hierarchy of this archive. The iterator creates DataNodes for each ZipEntry in this archive whose name begins with the supplied string level.
      Specified by:
      getChildIteratorAtLevel in class ZipArchiveDataNode
      Parameters:
      level - the required starting substring of the name of all ZipEntries to be represented in the result
      parent - the DataNode whose children the resulting nodes will be
      Returns:
      an Iterator over DataNode objects corresponding to the ZipEntry objects specified by level
      Throws:
      IOException

    • configureDetail

      public void configureDetail(DetailViewer dv)
      Description copied from class: DefaultDataNode
      No custom configuration is performed.
      Specified by:
      configureDetail in interface DataNode
      Overrides:
      configureDetail in class DefaultDataNode
      Parameters:
      dv - the detail viewer which this node is given an opportunity to configure
