Constructor Details

PrivateCredentialPermission

public PrivateCredentialPermission(String name, String actions)
Deprecated, for removal: This API element is subject to removal in a future version.
Creates a new PrivateCredentialPermission with the specified name. The name specifies both a Credential class and a Principal Set.
Parameters:
name - the name specifying the Credential class and Principal Set.
actions - the actions specifying that the Credential can be read.
Throws:
IllegalArgumentException - if name does not conform to the correct syntax or if actions is not "read".

Method Details

getCredentialClass

public String getCredentialClass()
Deprecated, for removal: This API element is subject to removal in a future version.
Returns the Class name of the Credential associated with this PrivateCredentialPermission.
Returns:
the Class name of the Credential associated with this PrivateCredentialPermission.

getPrincipals

public String[][] getPrincipals()
Deprecated, for removal: This API element is subject to removal in a future version.
Returns the 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.
Returns:
the Principal class and names associated with this PrivateCredentialPermission.

implies

public boolean implies(Permission p)
Deprecated, for removal: This API element is subject to removal in a future version.
Checks if this PrivateCredentialPermission implies the specified Permission.

This method returns true if:

  • p is an instanceof PrivateCredentialPermission and
  • the target name for p is 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:
implies in class Permission
Parameters:
p - the Permission to check against.
Returns:
true if this PrivateCredentialPermission implies the specified Permission, false if not.

equals

public boolean equals(Object obj)
Deprecated, for removal: This API element is subject to removal in a future version.
Checks two PrivateCredentialPermission objects for equality. Checks that obj is a PrivateCredentialPermission, 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:
equals in class Permission
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.

hashCode

public int hashCode()
Deprecated, for removal: This API element is subject to removal in a future version.
Returns the hash code value for this object.
Specified by:
hashCode in class Permission
Returns:
the hash code value for this object
See Also:

getActions

public String getActions()
Deprecated, for removal: This API element is subject to removal in a future version.
Returns the "canonical string representation" of the actions. This method always returns the String, "read".
Specified by:
getActions in class Permission
Returns:
the actions (always returns "read").

newPermissionCollection

public PermissionCollection newPermissionCollection()
Deprecated, for removal: This API element is subject to removal in a future version.
Return a homogeneous collection of PrivateCredentialPermissions in a PermissionCollection. No such PermissionCollection is defined, so this method always returns null.
Overrides:
newPermissionCollection in class Permission
Returns:
null in all cases.
