Message (org.faktorips.runtime 20.6.1-SNAPSHOT API)

java.lang.Object
- org.faktorips.runtime.Message

All Implemented Interfaces:

Serializable
```
public class Message
extends Object
implements Serializable
```
A human readable text message with an optional code that identifies the type of the message and a severity that indicates if this is an error, warning or information.
In addition a message provides access to the objects and their properties the message relates to. E.g. if a message reads that "insured person's age must be at least 18" than the person's age is invalid. This information can be used for example to mark controls in the UI that display this property.
If the provided message has replacement parameters that cannot be evaluated while creating the message text, it is possible to provide there parameters to the message object. Have a look at MsgReplacementParameter for further information.
If you need any further information stored with the message, it is possible to implement the IMarker object and provide some additional markers to the message. The exact use of the markers depends on the custom implementation.
Message is an immutable value object. Two message objects are considered equal if they have the same severity, code, text, "invalid properties" and replacement parameters.
