Constructors

public ProtectionDomain (CodeSource codesource, PermissionCollection permissions)

Creates a new ProtectionDomain with the given CodeSource and Permissions.

Creates a new ProtectionDomain with the given CodeSource and
Permissions. If the permissions object is not null, then
setReadOnly()) will be called on the passed in
Permissions object. The only permissions granted to this domain
are the ones specified; the current Policy will not be consulted.
Parameters:
- codesource - the codesource associated with this domain
- permissions - the permissions granted to this domain

public ProtectionDomain (CodeSource codesource, PermissionCollection permissions, ClassLoader classloader, Principal principals)

Creates a new ProtectionDomain qualified by the given CodeSource, Permissions, ClassLoader and array of Principals.

Creates a new ProtectionDomain qualified by the given CodeSource, Permissions, ClassLoader and array of Principals. If the permissions object is not null, then setReadOnly() will be called on the passed in Permissions object. The permissions granted to this domain are dynamic; they include both the static permissions passed to this constructor, and any permissions granted to this domain by the current Policy at the time a permission is checked.

This constructor is typically used by ClassLoaders and DomainCombiners which delegate to Policy to actively associate the permissions granted to this domain. This constructor affords the Policy provider the opportunity to augment the supplied PermissionCollection to reflect policy changes.

Parameters:
- codesource - the CodeSource associated with this domain
- permissions - the permissions granted to this domain
- classloader - the ClassLoader associated with this domain
- principals - the array of Principals associated with this domain. The contents of the array are copied to protect against subsequent modification.
