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

Example 1 with ExcludeRange

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

the class RancidAdapterConfigManager method interfaceInPackage.

/**
     * 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.
     * 
     * TODO: Factor this method out so that it can be reused? Or use an existing
     * utility method if one exists?
     * 
     * @param iface
     *            The interface to test against the package.
     * @param pkg
     *            The package to check for the inclusion of the interface.
     * 
     * @return True if the interface is included in the package, false
     *         otherwise.
