public Throwable getCause() {

} returns the previous exception. |
 abstract public SeverityEnum getSeverity()
subclasses need to define the getSeverity method to provide correct severity for logging. |
public String toString() {
String className = this.sourceClass.getName();
className = className.substring(className.lastIndexOf(".")); //$NON-NLS-1$
if (this.nestedException == null)
{
return Messages.getString("NestableException.msg", //$NON-NLS-1$
new Object[]{className, getMessage()});
}
return Messages.getString("NestableException.msgcause", //$NON-NLS-1$
new Object[]{className, getMessage(), this.nestedException.getMessage()});
} basic toString. Returns the message plus the previous exception (if a previous exception exists). |
