PagePermission (Apache JSPWiki 2.11.0.M6 API)

java.lang.Object
- java.security.Permission
- - org.apache.wiki.auth.permissions.PagePermission

All Implemented Interfaces:

Serializable, Guard
```
public final class PagePermission
extends Permission
implements Serializable
```
Permission to perform an operation on a single page or collection of pages in a given wiki. Permission actions include: view, edit (edit the text of a wiki page), comment, upload, modify (edit text and upload attachments), delete and rename.

The target of a permission is a single page or collection in a given wiki. The syntax for the target is the wiki name, followed by a colon (:) and the name of the page. "All wikis" can be specified using a wildcard (*). Page collections may also be specified using a wildcard. For pages, the wildcard may be a prefix, suffix, or all by itself. Examples of targets include:

*:* *:JanneJalkanen *:Jalkanen *:Janne* mywiki:JanneJalkanen mywiki:*Jalkanen mywiki:Janne*

For a given target, certain permissions imply others:
- delete and rename imply edit
- modify implies edit and upload
- edit implies comment and view
- comment and upload imply view

  - PagePermission
```
public PagePermission(String page,
                      String actions)
```
    Creates a new PagePermission for a specified page name and set of actions. Page should include a prepended wiki name followed by a colon (:). If the wiki name is not supplied or starts with a colon, the page refers to no wiki in particular, and will never imply any other PagePermission.
    
    Parameters:
    
    page - the wiki page
    
    actions - the allowed actions for this page
  - PagePermission
```
public PagePermission(WikiPage page,
                      String actions)
```
    Creates a new PagePermission for a specified page and set of actions.
    
    Parameters:
    
    page - The wikipage.
    
    actions - A set of actions; a comma-separated list of actions.
- Method Detail
  - equals
```
public boolean equals(Object obj)
```
    Two PagePermission objects are considered equal if their actions (after normalization), wiki and target are equal.
    
    Specified by:
    
    equals in class Permission
    
    Parameters:
    
    obj -
    
    Returns:
  - getActions
```
public String getActions()
```
    Returns the actions for this permission: "view", "edit", "comment", "modify", "upload" or "delete". The actions will always be sorted in alphabetic order, and will always appear in lower case.
    
    Specified by:
    
    getActions in class Permission
    
    Returns:
  - getPage
```
public String getPage()
```
    Returns the name of the wiki page represented by this permission.
    
    Returns:
    
    the page name
  - getWiki
```
public String getWiki()
```
    Returns the name of the wiki containing the page represented by this permission; may return the wildcard string.
    
    Returns:
    
    the wiki
  - hashCode
```

    hashCode in class Permission
    
    Returns:
  - implies
```
public boolean implies(Permission permission)
```
    PagePermission can only imply other PagePermissions; no other permission types are implied. One PagePermission implies another if its actions if three conditions are met:
    1. The other PagePermission's wiki is equal to, or a subset of, that of this permission. This permission's wiki is considered a superset of the other if it contains a matching prefix plus a wildcard, or a wildcard followed by a matching suffix.
    2. The other PagePermission's target is equal to, or a subset of, the target specified by this permission. This permission's target is considered a superset of the other if it contains a matching prefix plus a wildcard, or a wildcard followed by a matching suffix.
    3. All of other PagePermission's actions are equal to, or a subset of, those of this permission
    Specified by:
    
    implies in class Permission
    
    Parameters:
    
    permission -
    
    Returns:

public PermissionCollection newPermissionCollection()
```
    Returns a new AllPermissionCollection.
    
    Overrides:

    Returns:
    
    binary mask for implied actions
  - isSubset

protected static boolean isSubset(String superSet,
                                  String subSet)
```
    Determines whether one target string is a logical subset of the other.
    
    Parameters:
    
    superSet - the prospective superset
    
    subSet - the prospective subset
    
    Returns:
    
    the results of the test, where true indicates that subSet is a subset of superSet
  - createMask
```
protected static int createMask(String actions)
```
    Private method that creates a binary mask based on the actions specified. This is used by implies(Permission).
    
    Parameters:
