javax.security.auth.PrivateCredentialPermission
- All Implemented Interfaces:
Serializable,Guard
This class is used to protect access to private Credentials
belonging to a particular
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".- Since:

PrivateCredentialPermission
Creates a newPrivateCredentialPermissionwith the specifiedname. Thenamespecifies both a Credential class and aPrincipalSet.- Parameters:
name- the name specifying the Credential class andPrincipalSet.actions- the actions specifying that the Credential can be read.- Throws:
IllegalArgumentException- ifnamedoes not conform to the correct syntax or ifactionsis not "read".

Method Details
-
getCredentialClass
Returns the Class name of the Credential associated with thisPrivateCredentialPermission.- Returns:
- the Class name of the Credential associated with this
PrivateCredentialPermission.
-
getPrincipals
Returns thePrincipalclasses and names associated with thisPrivateCredentialPermission. The information is returned as a two-dimensional array (array[x][y]). The 'x' value corresponds to the number ofPrincipalclass and name pairs. When (y==0), it corresponds to thePrincipalclass value, and when (y==1), it corresponds to thePrincipalname value. For example, array[0][0] corresponds to the class name of the firstPrincipalin the array. array[0][1] corresponds to thePrincipalname of the firstPrincipalin the array.- Returns:
- the
Principalclass and names associated with thisPrivateCredentialPermission.
-
implies
Checks if thisPrivateCredentialPermissionimplies the specifiedPermission.This method returns true if:
-
pis an instanceof PrivateCredentialPermission and - the target name for
pis implied by this object's target name. For example:[* P1 "duke"] implies [a.b.Credential P1 "duke"]. [C1 P1 "duke"] implies [C1 P1 "duke" P2 "dukette"]. [C1 P2 "dukette"] implies [C1 P1 "duke" P2 "dukette"].
- Specified by:
impliesin classPermission- Parameters:
p- thePermissionto check against.- Returns:
- true if this
PrivateCredentialPermissionimplies the specifiedPermission, false if not.
-
-
equals
Checks twoPrivateCredentialPermissionobjects for equality. Checks thatobjis aPrivateCredentialPermission, and has the same credential class as this object, as well as the same Principals as this object. The order of the Principals in the respective Permission's target names is not relevant.- Specified by:
equalsin classPermission- Parameters:
obj- the object we are testing for equality with this object.- Returns:
- true if obj is a
PrivateCredentialPermission, has the same credential class as this object, and has the same Principals as this object. - See Also:
-
hashCode
public int hashCode()Returns the hash code value for this object.- Specified by:
hashCodein classPermission- Returns:
- a hash code value for this object.
- See Also:
-
getActions
Returns the "canonical string representation" of the actions. This method always returns the String, "read".- Specified by:
getActionsin classPermission- Returns:
- the actions (always returns "read").
-
newPermissionCollection
Return a homogeneous collection of PrivateCredentialPermissions in aPermissionCollection. No suchPermissionCollectionis defined, so this method always returnsnull.- Overrides:
newPermissionCollectionin classPermission- Returns:
- null in all cases.
