    static <F, T> IConverter<F,T>
    create(Function<F,T> conversion)
    Creates an untyped converter which calls the argument conversion function.

    Object
    getToType()
    Returns the type to which this converter can convert.

  • Method Details

    • getFromType

      Object getFromType()
      Returns the type whose instances can be converted by this converter. The return type is Object rather than Class to optionally support richer type systems than the one provided by Java reflection.
      Returns:
      the type whose instances can be converted, or null if this converter is untyped

    • getToType

      Object getToType()
      Returns the type to which this converter can convert. The return type is Object rather than Class to optionally support richer type systems than the one provided by Java reflection.
      Returns:
      the type to which this converter can convert, or null if this converter is untyped

    • convert

      T convert(F fromObject)
      Returns the result of the conversion of the given object.
      Parameters:
      fromObject - the object to convert, of type getFromType()
      Returns:
      the converted object, of type getToType()

    • create

      static <F, T> IConverter<F,T> create(Object fromType, Object toType, Function<F,T> conversion)
      Creates a converter which calls the argument conversion function.
      Parameters:
      fromType - the from type
      toType - the to type
      conversion - the conversion function
      Returns:
      the new converter

    • create

      static <F, T> IConverter<F,T> create(Function<F,T> conversion)
      Creates an untyped converter which calls the argument conversion function. null is used as the to and from types.
      Parameters:
      conversion - the conversion function
      Returns:
      the new converter
