Interface Converter<P,M>

Type Parameters:
P - the presentation type (e.g., String)
M - the model type (e.g., Integer, Date, BigDecimal)
All Known Implementing Classes:
StringToBigDecimalConverter, StringToBooleanConverter, StringToDateConverter, StringToDoubleConverter, StringToEnumConverter, StringToIntegerConverter, StringToLocalDateConverter, StringToLocalDateTimeConverter, StringToLongConverter
public interface Converter<P,M>
Bidirectional converter between a presentation type and a model type.

Converters translate values between their UI representation (typically String) and the Java type used in the domain model. For example, a Converter<String, Integer> converts the text "42" to the integer 42 and vice versa.

Usage:


 Converter<String, Integer> converter = new StringToIntegerConverter("Not a number");
 Integer value = converter.convertToModel("42");       // returns 42
 String text = converter.convertToPresentation(42);     // returns "42"
