From: erik Date: Sun, 18 May 2008 10:28:30 +0000 (+0000) Subject: Removed InterfaceRestriction. Now introduced a friendlier API in X-Git-Tag: wamblee-utils-0.2@603~97 X-Git-Url: http://wamblee.org/gitweb/?a=commitdiff_plain;h=afab432bc44aa00afbabd07eccaf5c7c11bad7b7;p=utils Removed InterfaceRestriction. Now introduced a friendlier API in the Container and filtering edges at the graph level. Filtering at graph level is more generic since it allows filtering of any edge (also required -> external required and external provided -> provided). --- diff --git a/trunk/system/general/src/main/java/org/wamblee/system/container/CompositeInterfaceRestriction.java b/trunk/system/general/src/main/java/org/wamblee/system/container/CompositeInterfaceRestriction.java deleted file mode 100644 index 041c75d2..00000000 --- a/trunk/system/general/src/main/java/org/wamblee/system/container/CompositeInterfaceRestriction.java +++ /dev/null @@ -1,75 +0,0 @@ -/* - * Copyright 2008 the original author or authors. - * - * 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 org.wamblee.system.container; - -import java.util.ArrayList; -import java.util.Collection; -import java.util.List; - -import org.wamblee.system.core.Component; -import org.wamblee.system.core.ProvidedInterface; -import org.wamblee.system.core.RequiredInterface; - - -/** - * Composite restriction that wraps a number of other restrictions.
