Method Detail

### addFormatterForFieldType

    void addFormatterForFieldType(Class<?> fieldType,
                                  Formatter<?> formatter)

  Adds a Formatter to format fields of a specific type.

  On print, if the Formatter's type T is declared and `fieldType` is not assignable to T, a coersion to T will be attempted before delegating to `formatter` to print a field value. On parse, if the parsed object returned by `formatter` is not assignable to the runtime field type, a coersion to the field type will be attempted before returning the parsed field value.

  Parameters:
    `fieldType` - the field type to format
    `formatter` - the formatter to add

### addFormatterForFieldType

    void addFormatterForFieldType(Class<?> fieldType,
                                  Printer<?> printer,
                                  Parser<?> parser)

  Adds a Printer/Parser pair to format fields of a specific type. The formatter will delegate to the specified `printer` for printing and the specified `parser` for parsing.

  On print, if the Printer's type T is declared and `fieldType` is not assignable to T, a coersion to T will be attempted before delegating to `printer` to print a field value. On parse, if the object returned by the Parser is not assignable to the runtime field type, a coersion to the field type will be attempted before returning the parsed field value.

  Parameters:
    `fieldType` - the field type to format
    `printer` - the printing part of the formatter
    `parser` - the parsing part of the formatter

### addFormatterForFieldAnnotation

    void addFormatterForFieldAnnotation(AnnotationFormatterFactory<? extends Annotation> annotationFormatterFactory)

  Adds a Formatter to format fields annotated with a specific format annotation.

  Parameters:
    `annotationFormatterFactory` - the annotation formatter factory to add
