public final class PrivateCredentialPermission extends Permission
Subject
. The Subject
is represented by a Set of Principals.
The target name of this Permission
specifies
a Credential class name, and a Set of Principals.
The only valid value for this Permission's actions is, "read".
The target name must abide by the following syntax:
CredentialClass {PrincipalClass "PrincipalName"}*For example, the following permission grants access to the com.sun.PrivateCredential owned by Subjects which have a com.sun.Principal with the name, "duke". Note that although this example, as well as all the examples below, do not contain Codebase, SignedBy, or Principal information in the grant statement (for simplicity reasons), actual policy configurations should specify that information when appropriate.
grant { permission javax.security.auth.PrivateCredentialPermission "com.sun.PrivateCredential com.sun.Principal \"duke\"", "read"; };If CredentialClass is "*", then access is granted to all private Credentials belonging to the specified
Subject
.
If "PrincipalName" is "*", then access is granted to the
specified Credential owned by any Subject
that has the
specified Principal
(the actual PrincipalName doesn't matter).
For example, the following grants access to the
a.b.Credential owned by any Subject
that has
an a.b.Principal.
grant { permission javax.security.auth.PrivateCredentialPermission "a.b.Credential a.b.Principal "*"", "read"; };If both the PrincipalClass and "PrincipalName" are "*", then access is granted to the specified Credential owned by any
Subject
.
In addition, the PrincipalClass/PrincipalName pairing may be repeated:
grant { permission javax.security.auth.PrivateCredentialPermission "a.b.Credential a.b.Principal "duke" c.d.Principal "dukette"", "read"; };The above grants access to the private Credential, "a.b.Credential", belonging to a
Subject
with at least two associated Principals:
"a.b.Principal" with the name, "duke", and "c.d.Principal", with the name,
"dukette".Constructor and Description |

. The name
specifies both a Credential class and a Principal
Set.

PrivateCredentialPermission
.public String[][] getPrincipals()
Principal
classes and names
associated with this PrivateCredentialPermission
.
The information is returned as a two-dimensional array (array[x][y]).
The 'x' value corresponds to the number of Principal
class and name pairs. When (y==0), it corresponds to
the Principal
class value, and when (y==1),
it corresponds to the Principal
name value.
For example, array[0][0] corresponds to the class name of
the first Principal
in the array. array[0][1]
corresponds to the Principal
name of the
first Principal
in the array.
