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

    StdDelegatingSerializer, StdDelegatingDeserializer

      Modifier and Type Method 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 cannot 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 cannot change static type parameter bindings).
