    • addIgnored

      public void addIgnored(String displayName)
      adds the given display name of a property to the ignore list. Can either be a complete path (e.g. __root__.options) or only a property name (e.g. options). In the latter case it matches all occurences of this display name.
      Parameters:
      displayName - the property to ignore

    • addIgnored

      public void addIgnored(Class<?> c, String displayName)
      adds the given class with the display name of a property to the ignore list. I.e. this property is only ignored for this class.
      Parameters:
      c - the class for which a property is to be ignored
      displayName - the property to ignore

      • m_Ignored

    • removeIgnored

      public boolean removeIgnored(String displayName)
      removes the given display name from the ignore list. returns whether the removing was succesful, i.e. whether the display name was in the list.
      Parameters:
      displayName - the property to remove from the ignore list
      Returns:
      whether the ignore list contained the specified property
      See Also:
      • m_Ignored

    • removeIgnored

      public boolean removeIgnored(Class<?> c, String displayName)
      removes the given display name from the ignore list of the class. returns whether the removing was succesful, i.e. whether the display name was in the list.
      Parameters:
      c - the class to remove the property from
      displayName - the property to remove from the ignore list
      Returns:
      whether the ignore list contained the specified property

      • m_Ignored

    • isIgnored

      public boolean isIgnored(String displayName)
      checks whether the given display name is an ignored property

      displayName - the property to check whether it is on the ignore list
      Returns:
      whether the property is in the ignored list
      See Also:
      • m_Ignored

    • isIgnored

      public boolean isIgnored(Class<?> c, String displayName)
      checks whether the given display name of a certain class is an ignored property. It only checks for this certain class and no derivative classes. If you also want to check for derivative classes, use isIgnored(Object,String).

      Parameters:
      o - the object to check the property for
      displayName - the property to check whether it is on the ignore list
      Returns:
      whether the property is in the ignored list
      See Also:
      • m_Ignored

    • allowed
