Class SObject

java.lang.Object

  +--org.exolab.jms.selector.SObject

public abstract class SObject

extends java.lang.Object

This class is the base class for classes adapting simple Java types. This is necessary to:

• reduce the number of types that the selector has to deal with. Expressions only evaluate to boolean, numeric and string types.
• Simplify operations (comparison, type checking etc.) on these types.
