Examples with ExcludeRange org.opennms.netmgt.config.poller.ExcludeRange used on opensource projects

Example 1 with ExcludeRange

use of org.opennms.netmgt.config.poller.ExcludeRange in project opennms by OpenNMS.

the class PollerConfigManager method isInterfaceInPackage.

/**
     * {@inheritDoc}
     *
     * This method is used to determine if the named interface is included in
     * the passed package definition. If the interface belongs to the package
     * then a value of true is returned. If the interface does not belong to the
     * package a false value is returned.
     *
     * <strong>Note: </strong>Evaluation of the interface against a package
     * filter will only work if the IP is already in the database.
