Converter (jackson-databind 2.6.0 API) (original) (raw)

• 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

  All Methods Instance Methods Abstract 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).
