Interface javax.infobus.InfoBusPropertyMap

public interface InfoBusPropertyMap
InfoBusPropertyMap is a temporary interface designed to provide a mechanism for use with InfoBus 1.1 components that wish to supply properties on DataItemChangeEvents. To use it, the producer implements the interface and provides a reference to the implementation class in the change event constructor.

When implementing this interface for InfoBus 1.1, an implementation of sun.com.java.util.collections.Map, such as HashMap may be used, delegating the get() method to the class.

In InfoBus 1.2, this class and its method will be deprecated. Constructors that use it will also be deprecated, and new constructors will be introduced that specify java.util.Map instead. Support for applications compiled with InfoBus 1.1 will be present by removing the get() method from InfoBusPropertyMap and adding a clause to have it extend java.util.Map.
