/* * Copyright (c) NoticeDog 2017. * GNU LESSER GENERAL PUBLIC LICENSE * Version 3, 29 June 2007 * * Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/> * Everyone is permitted to copy and distribute verbatim copies * of this license document, but changing it is not allowed. * * * This version of the GNU Lesser General Public License incorporates * the terms and conditions of version 3 of the GNU General Public * License, supplemented by the additional permissions listed below. * * 0. Additional Definitions. * * As used herein, "this License" refers to version 3 of the GNU Lesser * General Public License, and the "GNU GPL" refers to version 3 of the GNU * General Public License. * * "The Library" refers to a covered work governed by this License, * other than an Application or a Combined Work as defined below. * * An "Application" is any work that makes use of an interface provided * by the Library, but which is not otherwise based on the Library. * Defining a subclass of a class defined by the Library is deemed a mode * of using an interface provided by the Library. * * A "Combined Work" is a work produced by combining or linking an * Application with the Library. The particular version of the Library * with which the Combined Work was made is also called the "Linked * Version". * * The "Minimal Corresponding Source" for a Combined Work means the * Corresponding Source for the Combined Work, excluding any source code * for portions of the Combined Work that, considered in isolation, are * based on the Application, and not on the Linked Version. * * The "Corresponding Application Code" for a Combined Work means the * object code and/or source code for the Application, including any data * and utility programs needed for reproducing the Combined Work from the * Application, but excluding the System Libraries of the Combined Work. * * 1. Exception to Section 3 of the GNU GPL. * * You may convey a covered work under sections 3 and 4 of this License * without being bound by section 3 of the GNU GPL. * * 2. Conveying Modified Versions. * * If you modify a copy of the Library, and, in your modifications, a * facility refers to a function or data to be supplied by an Application * that uses the facility (other than as an argument passed when the * facility is invoked), then you may convey a copy of the modified * version: * * a) under this License, provided that you make a good faith effort to * ensure that, in the event an Application does not supply the * function or data, the facility still operates, and performs * whatever part of its purpose remains meaningful, or * * b) under the GNU GPL, with none of the additional permissions of * this License applicable to that copy. * * 3. Object Code Incorporating Material from Library Header Files. * * The object code form of an Application may incorporate material from * a header file that is part of the Library. You may convey such object * code under terms of your choice, provided that, if the incorporated * material is not limited to numerical parameters, data structure * layouts and accessors, or small macros, inline functions and templates * (ten or fewer lines in length), you do both of the following: * * a) Give prominent notice with each copy of the object code that the * Library is used in it and that the Library and its use are * covered by this License. * * b) Accompany the object code with a copy of the GNU GPL and this license * document. * * 4. Combined Works. * * You may convey a Combined Work under terms of your choice that, * taken together, effectively do not restrict modification of the * portions of the Library contained in the Combined Work and reverse * engineering for debugging such modifications, if you also do each of * the following: * * a) Give prominent notice with each copy of the Combined Work that * the Library is used in it and that the Library and its use are * covered by this License. * * b) Accompany the Combined Work with a copy of the GNU GPL and this license * document. * * c) For a Combined Work that displays copyright notices during * execution, include the copyright notice for the Library among * these notices, as well as a reference directing the user to the * copies of the GNU GPL and this license document. * * d) Do one of the following: * * 0) Convey the Minimal Corresponding Source under the terms of this * License, and the Corresponding Application Code in a form * suitable for, and under terms that permit, the user to * recombine or relink the Application with a modified version of * the Linked Version to produce a modified Combined Work, in the * manner specified by section 6 of the GNU GPL for conveying * Corresponding Source. * * 1) Use a suitable shared library mechanism for linking with the * Library. A suitable mechanism is one that (a) uses at run time * a copy of the Library already present on the user's computer * system, and (b) will operate properly with a modified version * of the Library that is interface-compatible with the Linked * Version. * * e) Provide Installation Information, but only if you would otherwise * be required to provide such information under section 6 of the * GNU GPL, and only to the extent that such information is * necessary to install and execute a modified version of the * Combined Work produced by recombining or relinking the * Application with a modified version of the Linked Version. (If * you use option 4d0, the Installation Information must accompany * the Minimal Corresponding Source and Corresponding Application * Code. If you use option 4d1, you must provide the Installation * Information in the manner specified by section 6 of the GNU GPL * for conveying Corresponding Source.) * * 5. Combined Libraries. * * You may place library facilities that are a work based on the * Library side by side in a single library together with other library * facilities that are not Applications and are not covered by this * License, and convey such a combined library under terms of your * choice, if you do both of the following: * * a) Accompany the combined library with a copy of the same work based * on the Library, uncombined with any other library facilities, * conveyed under the terms of this License. * * b) Give prominent notice with the combined library that part of it * is a work based on the Library, and explaining where to find the * accompanying uncombined form of the same work. * * 6. Revised Versions of the GNU Lesser General Public License. * * The Free Software Foundation may publish revised and/or new versions * of the GNU Lesser General Public License from time to time. Such new * versions will be similar in spirit to the present version, but may * differ in detail to address new problems or concerns. * * Each version is given a distinguishing version number. If the * Library as you received it specifies that a certain numbered version * of the GNU Lesser General Public License "or any later version" * applies to it, you have the option of following the terms and * conditions either of that published version or of any later version * published by the Free Software Foundation. If the Library as you * received it does not specify a version number of the GNU Lesser * General Public License, you may choose any version of the GNU Lesser * General Public License ever published by the Free Software Foundation. * * If the Library as you received it specifies that a proxy can decide * whether future versions of the GNU Lesser General Public License shall * apply, that proxy's public statement of acceptance of any version is * permanent authorization for you to choose that version for the * Library. */ package io.bunnyblue.noticedog.app.lockscreen.ui;
