Constructor Detail

CoordinationPermission

public CoordinationPermission(java.lang.String filter,
                              java.lang.String actions)
Creates a new granted CoordinationPermission object. This constructor must only be used to create a permission that is going to be checked.

Examples:

 (coordination.name=com.acme.*)
 (&(signer=\*,o=ACME,c=US)(coordination.name=com.acme.*))
 (signer=\*,o=ACME,c=US)
 

When a signer key is used within the filter expression the signer value must escape the special filter chars ('*', '(', ')').

The name is specified as a filter expression. The filter gives access to the following attributes:

Filter attribute names are processed in a case sensitive manner.

Parameters:
filter - A filter expression. Filter attribute names are processed in a case sensitive manner. A special value of "*" can be used to match all coordinations.
actions - admin, initiate or participate (canonical order).
Throws:
java.lang.IllegalArgumentException - If the filter has an invalid syntax.

CoordinationPermission

public CoordinationPermission(java.lang.String coordinationName,
                              Bundle coordinationBundle,
                              java.lang.String actions)
Creates a new requested CoordinationPermission object to be used by the code that must perform checkPermission. CoordinationPermission objects created with this constructor cannot be added to an CoordinationPermission permission collection.

Parameters:
coordinationName - The name of the requested Coordination.
coordinationBundle - The bundle which created the requested Coordination.
actions - admin, initiate or participate (canonical order).
Method Detail

implies

public boolean implies(java.security.Permission p)
Determines if the specified permission is implied by this object.

This method checks that the filter of the target is implied by the coordination name of this object. The list of CoordinationPermission actions must either match or allow for the list of the target object to imply the target CoordinationPermission action.

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 CoordinationPermission actions.

Always returns present CoordinationPermission actions in the following order: admin, initiate, participate.

Overrides:
getActions in class java.security.BasicPermission
Returns:
Canonical string representation of the CoordinationPermission actions.

newPermissionCollection

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

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 CoordinationPermission objects. This method checks that specified permission has the same name and CoordinationPermission actions as this CoordinationPermission object.

Overrides:
equals in class java.security.BasicPermission
Parameters:
obj - The object to test for equality with this CoordinationPermission object.
Returns:
true if obj is a CoordinationPermission, and has the same name and actions as this CoordinationPermission object; false otherwise.

hashCode

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

Overrides:
hashCode in class java.security.BasicPermission
Returns:
A hash code value for this object.
