Framework service to administer Conditional Permissions. Conditional Permissions can be added to, retrieved from, and removed from the framework. Conditional Permissions are conceptually managed in an ordered table called the Conditional Permission Table.

 public interface ConditionalPermissionAdmin {
Create a new Conditional Permission Info in the Conditional Permission Table.

The Conditional Permission Info will be given a unique, never reused name. This entry will be added at the beginning of the Conditional Permission Table with an access decision of ALLOW.

Since this method changes the Conditional Permission Table any ConditionalPermissionUpdates that were created prior to calling this method can no longer be committed.

Deprecated:
Since 1.1. Use newConditionalPermissionUpdate() instead.
Parameters:
conditions The conditions that need to be satisfied to enable the specified permissions. This argument can be null or an empty array indicating the specified permissions are not guarded by any conditions.
permissions The permissions that are enabled when the specified conditions, if any, are satisfied. This argument must not be null and must specify at least one permission.
Returns:
The ConditionalPermissionInfo for the specified Conditions and Permissions.
Throws:
java.lang.IllegalArgumentException If no permissions are specified.
java.lang.SecurityException If the caller does not have AllPermission.
 
 			ConditionInfo[] conditionsPermissionInfo[] permissions);

Set or create a Conditional Permission Info with a specified name in the Conditional Permission Table.

If the specified name is null, a new Conditional Permission Info must be created and will be given a unique, never reused name. If there is currently no Conditional Permission Info with the specified name, a new Conditional Permission Info must be created with the specified name. Otherwise, the Conditional Permission Info with the specified name must be updated with the specified Conditions and Permissions. If a new entry was created in the Conditional Permission Table it will be added at the beginning of the table with an access decision of ALLOW.

Since this method changes the underlying permission table any ConditionalPermissionUpdates that were created prior to calling this method can no longer be committed.

Deprecated:
Since 1.1. Use newConditionalPermissionUpdate() instead.
Parameters:
name The name of the Conditional Permission Info, or null.
conditions The conditions that need to be satisfied to enable the specified permissions. This argument can be null or an empty array indicating the specified permissions are not guarded by any conditions.
permissions The permissions that are enabled when the specified conditions, if any, are satisfied. This argument must not be null and must specify at least one permission.
Returns:
The ConditionalPermissionInfo for the specified name, Conditions and Permissions.
Throws:
java.lang.IllegalArgumentException If no permissions are specified.
java.lang.SecurityException If the caller does not have AllPermission.
			ConditionInfo[] conditionsPermissionInfo[] permissions);

Returns the Conditional Permission Infos from the Conditional Permission Table.

The returned Enumeration will return elements in the order they are kept in the Conditional Permission Table.

The Enumeration returned is based on a copy of the Conditional Permission Table and therefore will not throw exceptions if the Conditional Permission Table is changed during the course of reading elements from the Enumeration.

Deprecated:
Since 1.1. Use newConditionalPermissionUpdate() instead.
Returns:
An enumeration of the Conditional Permission Infos that are currently in the Conditional Permission Table.
Return the Conditional Permission Info with the specified name.

Deprecated:
Since 1.1. Use newConditionalPermissionUpdate() instead.
Parameters:
name The name of the Conditional Permission Info to be returned.
Returns:
The Conditional Permission Info with the specified name or null if no Conditional Permission Info with the specified name exists in the Conditional Permission Table.
Returns the Access Control Context that corresponds to the specified signers. The returned Access Control Context must act as if its protection domain came from a bundle that has the following characteristics:
  • It is signed by all of the given signers
  • It has a bundle id of -1
  • Its location is the empty string
  • Its state is UNINSTALLED
  • It has no headers
  • It has the empty version (0.0.0)
  • Its last modified time=0
  • Many methods will throw IllegalStateException because the state is UNINSTALLED
  • All other methods return a null

Parameters:
signers The signers for which to return an Access Control Context.
Returns:
An AccessControlContext that has the Permissions associated with the signer.
Creates a new update for the Conditional Permission Table. The update is a working copy of the current Conditional Permission Table. If the running Conditional Permission Table is modified before commit is called on the returned update, then the call to commit on the returned update will fail. That is, the commit method will return false and no change will be made to the running Conditional Permission Table. There is no requirement that commit is eventually called on the returned update.

Returns:
A new update for the Conditional Permission Table.
Since:
1.1
Creates a new ConditionalPermissionInfo with the specified fields suitable for insertion into a ConditionalPermissionUpdate. The delete method on ConditionalPermissionInfo objects created with this method must throw UnsupportedOperationException.

Parameters:
name The name of the created ConditionalPermissionInfo or null to have a unique name generated when the returned ConditionalPermissionInfo is committed in an update to the Conditional Permission Table.
conditions The conditions that need to be satisfied to enable the specified permissions. This argument can be null or an empty array indicating the specified permissions are not guarded by any conditions.
permissions The permissions that are enabled when the specified conditions, if any, are satisfied. This argument must not be null and must specify at least one permission.
access Access decision. Must be one of the following values:
  • allow
  • deny
The specified access decision value must be evaluated case insensitively.
Returns:
A ConditionalPermissionInfo object suitable for insertion into a ConditionalPermissionUpdate.
Throws:
java.lang.IllegalArgumentException If no permissions are specified or if the specified access decision is not a valid value.
Since:
1.1
			ConditionInfo[] conditionsPermissionInfo[] permissions,
			String access);

Creates a new ConditionalPermissionInfo from the specified encoded ConditionalPermissionInfo string suitable for insertion into a ConditionalPermissionUpdate. The delete method on ConditionalPermissionInfo objects created with this method must throw UnsupportedOperationException.

Parameters:
encodedConditionalPermissionInfo The encoded ConditionalPermissionInfo. White space in the encoded ConditionalPermissionInfo is ignored. The access decision value in the encoded ConditionalPermissionInfo must be evaluated case insensitively. If the encoded ConditionalPermissionInfo does not contain the optional name, null must be used for the name and a unique name will be generated when the returned ConditionalPermissionInfo is committed in an update to the Conditional Permission Table.
Returns:
A ConditionalPermissionInfo object suitable for insertion into a ConditionalPermissionUpdate.
Throws:
java.lang.IllegalArgumentException If the specified encodedConditionalPermissionInfo is not properly formatted.
Since:
1.1
