/**
 * RAFrameResourceAdaptorSbbInterface describes the interface between SBBs 
 * and the RAFrame resource adaptor. This interface provides means for SBBs 
 * to communicate with the resource adaptor.
 * <br>
 * RAFrameResourceAdaptorSbbInterface is defined in the deployment descriptor 
 * file "resource-adaptor-type-jar.xml". Therein, the tag <resource-adaptor-interface>
 * and its sub-tag <resource-adaptor-interface-name> reference to 
 * com.maretzke.raframe.ratype.RAFrameResourceAdaptorSbbInterface.
 * <br>
 * To be available for SBBs the deployment descriptor file "sbb-jar.xml" needs 
 * to bind a JNDI name to this interface. This is done in the tag
 * <resource-adaptor-entity-binding>. The tag <resource-adaptor-object-name> defines
 * the JNDI name of this interface: "slee/resources/raframe/1.0/sbb2ra".
 * <br>
 * The class com.maretzke.raframe.ra.RAFrameProvider implements this interface.
 * For further information, please refer to JAIN SLEE Specification 1.0, Final 
 * Release Page 239 and following pages.
