javax.security.jacc.EJBRoleRefPermission
- All Implemented Interfaces:
- Serializable, Guard
public final class EJBRoleRefPermission - extends Permission
- implements Serializable
Class for EJB isCallerInRole (String reference)
permissions. An EJBRoleRefPermission is a named permission and has actions.
The name of an EJBRoleRefPermission contains the value of the
ejb-name element in the application's deployment descriptor
that identifies the EJB in whose context the permission is
being evalutated.
the actions of an EJBRoleRefPermission identifies the role reference to
which the permission applies. An EJBRoleRefPermission is checked to
determine if the subject is a member of the role identified by the
reference.
Implementations of this class MAY implement newPermissionCollection or
inherit its implementation from the super class.

EJBRoleRefPermission
public EJBRoleRefPermission(String name,
String actions)
- Creates a new EJBRoleRefPermission with the specified name and actions.
- Parameters:
name - the ejb-name that identifies the EJB
in whose context the role references are
to be evaluated.
actions - identifies the role reference to which the permission
pertains. The role reference is scoped to the EJB identified
in the name parameter. The value of the role reference must not be
null or the empty string.
equals
public boolean equals(Object o)
- Checks two EJBRoleRefPermission objects for equality.
EJBRoleRefPermission objects are equivalent if they have case
equivalent name and actions values.
Two Permission objects, P1 and P2, are equivalent if and only if
P1.implies(P2) && P2.implies(P1).
- Specified by:
equals in class Permission
- Parameters:
o - the EJBRoleRefPermission object being tested for equality
with this EJBRoleRefPermission.
- Returns:
- true if the argument EJBRoleRefPermission object is equivalent
to this EJBRoleRefPermission.
getActions
public String getActions()
- Returns a canonical String representation of the actions of this
EJBRoleRefPermission.
- Specified by:
getActions in class Permission
- Returns:
- a String containing the canonicalized actions of this
EJBRoleRefPermission.
hashCode
public int hashCode()
- Returns the hash code value for this EJBRoleRefPermission. The properties
of the returned hash code must be as follows:
- During the lifetime of a Java application, the hashCode method
must return the same integer value, every time it is called on a
EJBRoleRefPermission object. The value returned by hashCode for a
particular EJBRoleRefPermission need not remain consistent from
one execution of an application to another.
- If two EJBRoleRefPermission objects are equal according to the
equals method, then calling the hashCode method on each of the two
Permission objects must produce the same integer result (within an
application).
- Specified by:
hashCode in class Permission
- Returns:
- the integer hash code value for this object.
implies
public boolean implies(Permission permission)
- Determines if the argument Permission is "implied by" this
EJBRoleRefPermission. For this to be the case,
- The argument must be an instanceof EJBRoleRefPermission
- with name equivalent to that of this EJBRoleRefPermission, and
- with the role reference equivalent to that of this
EJBRoleRefPermission applies.
The name and actions comparisons described above are case sensitive.
- Specified by:
implies in class Permission
- Parameters:
permission - "this" EJBRoleRefPermission is checked to see if
it implies the argument permission.
- Returns:
- true if the specified permission is implied by this object,
false if not.
