Example 1 with GenericObjectPool

use of org.apache.tomcat.dbcp.pool2.impl.GenericObjectPool in project tomcat by apache.

the class BasicDataSource method createConnectionPool.

     * timeBetweenEvictionRunsMillis.  Setting that property is deferred to
     * {@link #startPoolMaintenance()}, since setting timeBetweenEvictionRunsMillis
     * to a positive value causes {@link GenericObjectPool}'s eviction timer
     * to be started.
