The value of the attribute is {@code null} * for entries that do not have access permissions. Zip file systems do not * enforce access permissions. * * <p> The "permissions" attribute may be read and set using the * {@linkplain Files#getAttribute(Path, String, LinkOption...) Files.getAttribute} and * {@linkplain Files#setAttribute(Path, String, Object, LinkOption...) Files.setAttribute} * methods. The following example uses these methods to read and set the attribute: * <pre> {@code * Set<PosixFilePermission> perms = Files.getAttribute(entry, "zip:permissions"); * if (perms == null) { * perms = PosixFilePermissions.fromString("rw-rw-rw-"); * Files.setAttribute(entry, "zip:permissions", perms); * } * } </pre> * * <p> In addition to the "{@code zip}" view, a Zip file system optionally supports * the {@link PosixFileAttributeView} ("{@code posix}"). * This view extends the "{@code basic}" view with type safe access to the * {@link PosixFileAttributes#owner() owner}, {@link PosixFileAttributes#group() group-owner}, * and {@link PosixFileAttributes#permissions() permissions} attributes. The * "{@code posix}" view is only supported when the Zip file system is created with * the provider property "{@code enablePosixFileAttributes}" set to "{@code true}". * The following creates a file system with this property and reads the access * permissions of a file: * <pre> {@code * var env = Map.of("enablePosixFileAttributes", "true"); * try (FileSystem fs = FileSystems.newFileSystem(file, env) { * Path entry = fs.getPath("entry"); * Set<PosixFilePermission> perms = Files.getPosixFilePermissions(entry); * } * } </pre> * * <p> The file owner and group owner attributes are not persisted, meaning they are * not stored in the zip file. The "{@code defaultOwner}" and "{@code defaultGroup}" * provider properties (listed below) can be used to configure the default values * for these attributes. If these properties are not set then the file owner * defaults to the owner of the zip file, and the group owner defaults to the * zip file's group owner (or the file owner on platforms that don't support a * group owner). * * <p> The "{@code permissions}" attribute is not optional in the "{@code posix}" * view so a default set of permissions are used for entries that do not have * access permissions stored in the Zip file. The default set of permissions * are * <ul> * <li>{@link PosixFilePermission#OWNER_READ OWNER_READ}</li> * <li>{@link PosixFilePermission#OWNER_WRITE OWNER_WRITE}</li> * <li>{@link PosixFilePermission#GROUP_READ GROUP_READ}</li> * </ul> * The default permissions can be configured with the "{@code defaultPermissions}" * property described below. * * <h2>Zip File System Properties</h2> * * The following properties may be specified when creating a Zip * file system: * <table class="striped"> * <caption style="display:none"> * Configurable properties that may be specified when creating * a new Zip file system * </caption> * <thead> * <tr> * <th scope="col">Property Name</th> * <th scope="col">Data Type</th> * <th scope="col">Default Value</th> * <th scope="col">Description</th> * </tr> * </thead> * * <tbody> * <tr> * <th scope="row">create</th> * <td>{@link java.lang.String} or {@link java.lang.Boolean}</td> * <td>false</td> * <td> * If the value is {@code true}, the Zip file system provider * creates a new Zip or JAR file if it does not exist. * </td> * </tr> * <tr> * <th scope="row">encoding</th> * <td>{@link java.lang.String}</td> * <td>UTF-8</td> * <td> * The value indicates the encoding scheme for the * names of the entries in the Zip or JAR file. * </td> * </tr> * <tr> * <th scope="row">enablePosixFileAttributes</th> * <td>{@link java.lang.String} or {@link java.lang.Boolean}</td> * <td>false</td> * <td> * If the value is {@code true}, the Zip file system will support * the {@link java.nio.file.attribute.PosixFileAttributeView PosixFileAttributeView}. * </td> * </tr> * <tr> * <th scope="row">defaultOwner</th> * <td>{@link java.nio.file.attribute.UserPrincipal UserPrincipal}<br> or * {@link java.lang.String}</td> * <td>null/unset</td> * <td> * Override the default owner for entries in the Zip file system.<br> * The value can be a UserPrincipal or a String value that is used as the UserPrincipal's name. * </td> * </tr> * <tr> * <th scope="row">defaultGroup</th> * <td>{@link java.nio.file.attribute.GroupPrincipal GroupPrincipal}<br> or * {@link java.lang.String}</td> * <td>null/unset</td> * <td> * Override the the default group for entries in the Zip file system.<br> * The value can be a GroupPrincipal or a String value that is used as the GroupPrincipal's name. * </td> * </tr> * <tr> * <th scope="row">defaultPermissions</th> * <td>{@link java.util.Set Set}<{@link java.nio.file.attribute.PosixFilePermission PosixFilePermission}><br> * or {@link java.lang.String}</td> * <td>null/unset</td> * <td> * Override the default Set of permissions for entries in the Zip file system.<br> * The value can be a {@link java.util.Set Set}<{@link java.nio.file.attribute.PosixFilePermission PosixFilePermission}> or<br> * a String that is parsed by {@link java.nio.file.attribute.PosixFilePermissions#fromString PosixFilePermissions::fromString} * </td> * </tr> * <tr> * <th scope="row">compressionMethod</th> * <td>{@link java.lang.String}</td> * <td>"DEFLATED"</td> * <td> * The value representing the compression method to use when writing entries * to the Zip file system. * <ul> * <li> * If the value is {@code "STORED"}, the Zip file system provider will * not compress entries when writing to the Zip file system. * </li> * <li> * If the value is {@code "DEFLATED"} or the property is not set, * the Zip file system provider will use data compression when * writing entries to the Zip file system. * </li> * <li> * If the value is not {@code "STORED"} or {@code "DEFLATED"}, an * {@code IllegalArgumentException} will be thrown when the Zip * filesystem is created. * </li> * </ul> * </td> * </tr> * <tr> * <th scope="row">releaseVersion</th> * <td>{@link java.lang.String} or {@link java.lang.Integer}</td> * <td>null/unset</td> * <td> * A value representing the version entry to use when accessing a * <a href="{@docRoot}/../specs/jar/jar.html#multi-release-jar-files"> * multi-release JAR</a>.
