  • Constructor Details

    • PropertyManipulator

      public PropertyManipulator()
      Default constructor (necessary for the ExternalizableLite interface).

    • PropertyManipulator

      public PropertyManipulator(String sName)
      Construct a PropertyManipulator for the specified property name.

      This constructor assumes that the corresponding property getter will have a name of ("get" + sName) and the corresponding property setter's name will be ("set + sName).

      Parameters:
      sName - a property name

    • PropertyManipulator

      public PropertyManipulator(String sName, boolean fUseIs)
      Construct a PropertyManipulator for the specified property name.

      This constructor assumes that the corresponding property getter will have a name of either ("get" + sName) or ("is + sName) and the corresponding property setter's name will be ("set + sName).

      Parameters:
      sName - a property name
      fUseIs - if true, the getter method will be prefixed with "is" rather than "get"
