The special action "*" will represent all actions. The resolve action is implied by the class, execute and resource actions.

The name of this permission is a filter expression. The filter gives access to the following attributes:

signer - A Distinguished Name chain used to sign a bundle. Wildcards in a DN are not matched according to the filter string rules, but according to the rules defined for a DN chain.
location - The location of a bundle.
id - The bundle ID of the designated bundle.
name - The symbolic name of a bundle.

Filter attribute names are processed in a case sensitive manner.

- Constructor Detail
  - AdminPermission
```
public AdminPermission()
```
    Creates a new AdminPermission object that matches all bundles and has all actions. Equivalent to AdminPermission("*","*");
  - AdminPermission
```
public AdminPermission(String filter,
                       String actions)
```
    Create a new AdminPermission. This constructor must only be used to create a permission that is going to be checked.
    Examples:
```
 (signer=\*,o=ACME,c=US)
 (&(signer=\*,o=ACME,c=US)(name=com.acme.*)
   (location=http://www.acme.com/bundles/*))
 (id>=1)
 
```
    When a signer key is used within the filter expression the signer value must escape the special filter chars ('*', '(', ')').
    Null arguments are equivalent to "*".
    Parameters:
    
    filter - A filter expression that can use signer, location, id, and name keys. A value of "*" or null matches all bundle. Filter attribute names are processed in a case sensitive manner.
    
    actions - class, execute, extensionLifecycle , lifecycle, listener, metadata, resolve , resource, startlevel, context or weave. A value of "*" or null indicates all actions.
    
    Throws:
    
    IllegalArgumentException - If the filter has an invalid syntax.
  - AdminPermission
```
public AdminPermission(Bundle bundle,
                       String actions)
```
    Creates a new requested AdminPermission object to be used by the code that must perform checkPermission. AdminPermission objects created with this constructor cannot be added to an AdminPermission permission collection.
    
    Parameters:
    
    bundle - A bundle.
    
    actions - class, execute, extensionLifecycle , lifecycle, listener, metadata, resolve , resource, startlevel, context, weave. A value of "*" or null indicates all actions.
    
    Since:
    
    1.3
- Method Detail
  - implies
```
public boolean implies(Permission p)
```
    Determines if the specified permission is implied by this object. This method throws an exception if the specified permission was not constructed with a bundle.
    This method returns true if the specified permission is an AdminPermission AND
    - this object's filter matches the specified permission's bundle ID, bundle symbolic name, bundle location and bundle signer distinguished name chain OR
    - this object's filter is "*"
    AND this object's actions include all of the specified permission's actions.
    Special case: if the specified permission was constructed with "*" filter, then this method returns true if this object's filter is "*" and this object's actions include all of the specified permission's actions
    Overrides:
    
    implies in class BasicPermission
    
    Parameters:
    
    p - The requested permission.
    
    Returns:
    
    true if the specified permission is implied by this object; false otherwise.
  - getActions

```
    Returns the canonical string representation of the AdminPermission actions.
    Always returns present AdminPermission actions in the following order: class, execute, extensionLifecycle, lifecycle, listener, metadata, resolve, resource, startlevel, context, weave.
    
    Overrides:
    
    getActions in class BasicPermission

```
    Returns the hash code value for this object.
