Class SinglePoolConnectionInterceptor

java.lang.Object
  org.apache.geronimo.connector.outbound.AbstractSinglePoolConnectionInterceptor
      org.apache.geronimo.connector.outbound.SinglePoolConnectionInterceptor

All Implemented Interfaces:

ConnectionInterceptor, PoolingAttributes

public class SinglePoolConnectionInterceptor
extends AbstractSinglePoolConnectionInterceptor

SinglePoolConnectionInterceptor chooses a single connection from the pool. If selectOneAssumeMatch is true, it simply returns the selected connection. THIS SHOULD BE USED ONLY IF MAXIMUM SPEED IS ESSENTIAL AND YOU HAVE THOROUGLY CHECKED THAT MATCHING WOULD SUCCEED ON THE SELECTED CONNECTION. (i.e., read the docs on your connector to find out how matching works) If selectOneAssumeMatch is false, it checks with the ManagedConnectionFactory that the selected connection does match before returning it: if not it throws an exception.
