public interface Code
     
     

      
      extends 
      
      Serializable
     
     

This interface defines error and exception codes to identify exception classes.

It is intended that this interface is implemented by enumerations that define all or part of these codes for an application.

Since the implementing classes are used as members of exceptions they have to be serializable. Instances of implementing classes should also be immutable.

Method Summary

String	getCode() Returns the string representation of the code.
String	getComponentId() Returns the component identifier that raised an exception with this code.
String	getDisplayId() Returns the string representation of the code.
String	toString() Returns the string representation of the code.

Method Detail

getComponentId

String getComponentId()

Returns the component identifier that raised an exception with this code.

This number enables the system to separate the error codes of different sub systems.

Returns:

the component identifier.

getCode

String getCode()

Returns the string representation of the code.

This is the code within the component and lacks the component identifier. If the component is interested in the code, this identifier is used.

Returns:

the string representation of the code.

getDisplayId

String getDisplayId()

Returns the string representation of the code. This includes the component identifier and the code. If the code is presented (e.g. in a log file) the return value of this method is used.

This returns the same value as toString() as this method can be used via property getter.

Returns:

the string representation of the code.

toString

String toString()

Returns the string representation of the code. This includes the component identifier and the code. If the code is presented (e.g. in a log file) the return value of this method is used.

This returns the same value as getDisplayId() as this makes it easier to print the code in a String context (e.g. writing to a log file).

Overrides:

toString in class Object

Returns:

the string representation of the code.
