addFormatterForFieldType

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

Adds a Formatter to format fields of the given type.

On print, if the Formatter's type T is declared and fieldType is not assignable to T, a coercion 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 coercion 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 coercion 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 coercion 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
