@Deprecated(since="17", forRemoval=true) public abstract class PolicySpi extends Object
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.

public PolicySpi()
protected abstract boolean engineImplies(ProtectionDomain domain, Permission permission)
domain
- the ProtectionDomain to check.permission
- check whether this permission is granted to the specified domain.true
if the permission is granted to the domain.protected void engineRefresh()
refresh
on 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.
protected PermissionCollection engineGetPermissions(CodeSource 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.
codesource
- the CodeSource to which the returned PermissionCollection has been granted.protected PermissionCollection engineGetPermissions(ProtectionDomain domain)
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.
domain
- the ProtectionDomain to which the returned PermissionCollection has been granted.
