Class PrivateCredentialPermission

public final class PrivateCredentialPermission extends Permission implements Serializable

A permission governing access to a private credential. The action of this permission is always "read" -- meaning that the private credential information can be read from an object.

The target of this permission is formatted as follows:

CredentialClassName ( PrinicpalClassName PrincipalName )*

CredentialClassName is either the name of a private credential class name, or a wildcard character ('*'). PrinicpalClassName is the class name of a principal object, and PrincipalName is a string representing the principal, or the wildcard character.

Constructor Summary
	PrivateCredentialPermission(String name, String actions) Create a new private credential permission.

Method Summary
boolean	equals(Object o)
String	getActions() Returns the actions this permission encompasses.
String	getCredentialClass() Returns the credential class name that was embedded in this permission's target name.
String[][]	getPrincipals() Returns the principal list that was embedded in this permission's target name.
int	hashCode()
boolean	implies(Permission p) Test if this permission implies another.
PermissionCollection	newPermissionCollection() This method is not necessary for this class, thus it always returns null.

Constructor Detail

PrivateCredentialPermission

public PrivateCredentialPermission(String name, String actions)

Create a new private credential permission.

Parameters: name The permission target name. actions The list of actions, which, for this class, must be "read".

hashCode

public int hashCode()

implies

public boolean implies(Permission p)

Test if this permission implies another. This method returns true if:

p is an instance of PrivateCredentialPermission
The credential class name of this instance matches that of p, and one of the principals of p is contained in the principals of this class. Thus,
- [ * P "foo" ] implies [ C P "foo" ]
- [ C P1 "foo" ] implies [ C P1 "foo" P2 "bar" ]
- [ C P1 "*" ] implies [ C P1 "foo" ]

Parameters: p The permission to check.

Returns: True if this permission implies p.

newPermissionCollection

public PermissionCollection newPermissionCollection()
