Constructor Detail

AdminPermission

public AdminPermission()
Creates a new AdminPermission object that matches all bundles and has all actions. Equivalent to AdminPermission("*","*");


AdminPermission

public AdminPermission(java.lang.String filter,
                       java.lang.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:
java.lang.IllegalArgumentException - If the filter has an invalid syntax.

AdminPermission

public AdminPermission(Bundle bundle,
                       java.lang.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(java.security.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

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 java.security.BasicPermission
Parameters:
p - The requested permission.
Returns:
true if the specified permission is implied by this object; false otherwise.

getActions

public java.lang.String 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 java.security.BasicPermission
Returns:
Canonical string representation of the AdminPermission actions.

newPermissionCollection

public java.security.PermissionCollection newPermissionCollection()
Returns a new PermissionCollection object suitable for storing AdminPermissions.

Overrides:
newPermissionCollection in class java.security.BasicPermission
Returns:
A new PermissionCollection object.

equals

public boolean equals(java.lang.Object obj)
Determines the equality of two AdminPermission objects.

Overrides:
equals in class java.security.BasicPermission
Parameters:
obj - The object being compared for equality with this object.
Returns:
true if obj is equivalent to this AdminPermission; false otherwise.

hashCode

public int hashCode()
Returns the hash code value for this object.

Overrides:
hashCode in class java.security.BasicPermission
Returns:
