All Implemented Interfaces:

Serializable

public class Message
extends Object
implements Serializable

A Message is an instance of a MessageTemplate with parameters bound to it
A Message instance is e.g. useful for error/validation reporting.

Example creating a Message from a MessageTemplate4:

 MessageTemplate4<String, BigDecimal, BigDecimal, LocalDate> ACCOUNT_OVERDRAWN = ROOT.key4("ACCOUNT_OVERDRAWN",
                                                                                           "Account {0} is overdrawn by ${1}. A fee of ${2} will be debited on the {3}");

 String accountId = "Account1";
 BigDecimal overdrawnAmount = new BigDecimal("125");
 BigDecimal feeAmount = new BigDecimal("10");
 LocalDate  feeDebitDate =  LocalDate.of(2023, 2, 25);
 Message msg = ACCOUNT_OVERDRAWN.create(accountId,
                                        overdrawnAmount,
                                        feeAmount,
                                        feeDebitDate);

 

will create a Message with getMessage(): "Account Account1 is overdrawn by $125. A fee of $10 will be debited on the 2023-2-25" (date formatting is dependent on the Locale)
