Class RepeatHandler

java.lang.Object
  fi.hut.tml.xsmiles.mlfc.xforms.ui.RepeatHandler

public class RepeatHandler

extends java.lang.Object

The handler for repeats. This class handles "expanding" the UI dom depending on the nodeset that the repeat is bound. This class does not handle the index (cursor in the UI).
