From 6509e0875c394fa122e56bbaa93b2f11205d1d67 Mon Sep 17 00:00:00 2001 From: Marek Gradzki Date: Wed, 20 Jul 2016 09:48:14 +0200 Subject: HONEYCOMB-118: extend classifer model to support node names. * configuration write is supported (updates local cache with relative node mapping) * operational read is supported only for nodes with existing relative node mapping * ACL support (using vpp-classfier or ietf-acl model) is not affected by the patch (tables/sessions for access controll refer to neighbour nodes as packet-handling-action, not vpp-node-name) Change-Id: Ice0c846803cc7e8960c3571fd2a13ed46ba53702 Signed-off-by: Marek Gradzki --- .../vppclassifier/VppClassifierContextManager.java | 106 +++++++++++++++++++++ 1 file changed, 106 insertions(+) create mode 100644 v3po/v3po2vpp/src/main/java/io/fd/honeycomb/translate/v3po/vppclassifier/VppClassifierContextManager.java (limited to 'v3po/v3po2vpp/src/main/java/io/fd/honeycomb/translate/v3po/vppclassifier/VppClassifierContextManager.java') diff --git a/v3po/v3po2vpp/src/main/java/io/fd/honeycomb/translate/v3po/vppclassifier/VppClassifierContextManager.java b/v3po/v3po2vpp/src/main/java/io/fd/honeycomb/translate/v3po/vppclassifier/VppClassifierContextManager.java new file mode 100644 index 000000000..7e9b6d6d5 --- /dev/null +++ b/v3po/v3po2vpp/src/main/java/io/fd/honeycomb/translate/v3po/vppclassifier/VppClassifierContextManager.java @@ -0,0 +1,106 @@ +/* + * Copyright (c) 2016 Cisco and/or its affiliates. + * + * Licensed under the Apache License, Version 2.0 (the "License"); + * you may not use this file except in compliance with the License. + * You may obtain a copy of the License at: + * + * http://www.apache.org/licenses/LICENSE-2.0 + * + * Unless required by applicable law or agreed to in writing, software + * distributed under the License is distributed on an "AS IS" BASIS, + * WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. + * See the License for the specific language governing permissions and + * limitations under the License. + */ + +package io.fd.honeycomb.translate.v3po.vppclassifier; + +import com.google.common.base.Optional; +import io.fd.honeycomb.translate.MappingContext; +import javax.annotation.Nonnull; +import javax.annotation.Nullable; +import org.opendaylight.yang.gen.v1.urn.opendaylight.params.xml.ns.yang.vpp.classifier.rev150603.VppNodeName; + +/** + * Manages metadata for vpp-classifier + */ +public interface VppClassifierContextManager { + + /** + * Creates metadata for classify table. + * + * @param id classify table index + * @param name classify table name + * @param classifierNode name of VPP node the table is defined for + * @param ctx mapping context providing context data for current transaction + */ + void addTable(final int id, @Nonnull final String name, @Nullable final VppNodeName classifierNode, + @Nonnull final MappingContext ctx); + + /** + * Check whether metadata for given classify table metadata is present. + * + * @param name classify table name + * @param ctx mapping context providing context data for current transaction + * @return true if present, false otherwise + */ + boolean containsTable(@Nonnull String name, @Nonnull final MappingContext ctx); + + /** + * Returns classify table index associated with the given name. + * + * @param name classify table name + * @param ctx mapping context providing context data for current transaction + * @return integer index value matching supplied classify table name + * @throws IllegalArgumentException if classify table was not found + */ + int getTableIndex(@Nonnull final String name, @Nonnull final MappingContext ctx); + + /** + * Retrieves classify table name for given id.
