Policy class.
 All the abstract methods in this class must be implemented by each
 service provider who wishes to supply a Policy implementation.
  Subclass implementations of this abstract class must provide
 a public constructor that takes a Policy.Parameters
 object as an input parameter.  This constructor also must throw
 an IllegalArgumentException if it does not understand the
 Policy.Parameters input.

Method Details- 
engineImpliesDeprecated, for removal: This API element is subject to removal in a future version.Check whether the policy has granted a Permission to a ProtectionDomain.- Parameters:
- domain- the ProtectionDomain to check.
- permission- check whether this permission is granted to the specified domain.
- Returns:
- boolean true if the permission is granted to the domain.

engineRefreshprotected void engineRefresh()Deprecated, for removal: This API element is subject to removal in a future version.Refreshes/reloads the policy configuration. The behavior of this method depends on the implementation. For example, callingrefreshon a file-based policy will cause the file to be re-read.The default implementation of this method does nothing. This method should be overridden if a refresh operation is supported by the policy implementation. 
- 
engineGetPermissionsDeprecated, for removal: This API element is subject to removal in a future version.Return a PermissionCollection object containing the set of permissions granted to the specified CodeSource.The default implementation of this method returns Policy.UNSUPPORTED_EMPTY_COLLECTION object. This method can be overridden if the policy implementation can return a set of permissions granted to a CodeSource. - Parameters:
- codesource- the CodeSource to which the returned PermissionCollection has been granted.
- Returns:
- a set of permissions granted to the specified CodeSource. If this operation is supported, the returned set of permissions must be a new mutable instance and it must support heterogeneous Permission types. If this operation is not supported, Policy.UNSUPPORTED_EMPTY_COLLECTION is returned.

engineGetPermissionsDeprecated, for removal: This API element is subject to removal in a future version.Return a PermissionCollection object containing the set of permissions granted to the specified ProtectionDomain.The default implementation of this method returns Policy.UNSUPPORTED_EMPTY_COLLECTION object. This method can be overridden if the policy implementation can return a set of permissions granted to a ProtectionDomain. - Parameters:
- domain- the ProtectionDomain to which the returned PermissionCollection has been granted.
- Returns:
- a set of permissions granted to the specified ProtectionDomain. If this operation is supported, the returned set of permissions must be a new mutable instance and it must support heterogeneous Permission types. If this operation is not supported, Policy.UNSUPPORTED_EMPTY_COLLECTION is returned.
