Class Assert

java.lang.Object
oracle.odi.domain.util.Assert

public class Assert

extends java.lang.Object

This class is designed as replacement of Spring's Assert, but with support of I18N ODI MessageHandle.
Each method with MessageHandle has version without this argument. In such case it will use default messages. If no arguments is passed to default version of method it will use generic version of message (e.g. "Parameter must be true." instead of "Parameter 'paramName' must be true.").

Since:

release specific (what release of product did this appear in)
