Interface Converter<IN,OUT>

  • Type Parameters:
    IN - Type of values converter takes
    OUT - Result type from conversion
    All Known Implementing Classes:
    Converter.None, StdConverter

    public interface Converter<IN,OUT>
    Helper interface for things that convert Objects of one type to another.

    NOTE: implementors are strongly encouraged to extend StdConverter instead of directly implementing Converter, since that can help with default implementation of typically boiler-plate code.

    Since:
    2.1

    • Nested Class Summary

      Nested Classes 
      Modifier and Type Interface and Description
      static class  Converter.None
      This marker class is only to be used with annotations, to indicate that no converter is to be used.

    • Method Summary

      Methods 
      Modifier and Type Method and Description
      OUT convert(IN value)
      Main conversion method.
      JavaType getInputType(TypeFactory typeFactory)
      Method that can be used to find out actual input (source) type; this usually can be determined from type parameters, but may need to be implemented differently from programmatically defined converters (which can not change static type parameter bindings).
      JavaType getOutputType(TypeFactory typeFactory)
      Method that can be used to find out actual output (target) type; this usually can be determined from type parameters, but may need to be implemented differently from programmatically defined converters (which can not change static type parameter bindings).
