  • Method Details

    • get

      public <T> T get(String name, Class<T> type)
      Description copied from interface: ValueMap
      Get a named property and convert it into the given type. This method does not support conversion into a primitive type or an array of a primitive type. It should return null in this case.
      Specified by:
      get in interface ValueMap
      Type Parameters:
      T - The class of the type
      Parameters:
      name - The name of the property
      type - The class of the type
      Returns:
      Return named value converted to type T or null if non existing or can't be converted.

    • get

      public <T> T get(String name, T defaultValue)
      Description copied from interface: ValueMap
      Get a named property and convert it into the given type. This method does not support conversion into a primitive type or an array of a primitive type. It should return the default value in this case.

      Implementation hint: In the past it was allowed to call this with a 2nd parameter being null. Therefore all implementations should internally call Map.get(Object) when the 2nd parameter has value null.
      Specified by:
      get in interface ValueMap
      Type Parameters:
      T - The expected type
      Parameters:
      name - The name of the property
      defaultValue - The default value to use if the named property does not exist or cannot be converted to the requested type. The default value is also used to define the type to convert the value to. Must not be null. If you want to return null by default rather rely on ValueMap.get(String, Class).
      Returns:
      Return named value converted to type T or the default value if non existing or can't be converted.
