Method from javax.crypto.CryptoAllPermissionCollection Detail:
public void add(Permission permission) { if (isReadOnly()) throw new SecurityException("attempt to add a Permission to " + "a readonly PermissionCollection"); if (permission != CryptoAllPermission.INSTANCE) return; all_allowed = true; } Adds a permission to the CryptoAllPermissions.
public Enumeration elements() { Vector v = new Vector(1); if (all_allowed) v.add(CryptoAllPermission.INSTANCE); return v.elements(); } Returns an enumeration of all the CryptoAllPermission objects in the container.
public boolean implies(Permission permission) { if (!(permission instanceof CryptoPermission)) { return false; } return all_allowed; } Check and see if this set of permissions implies the permissions expressed in "permission".

Method from javax.crypto.CryptoAllPermissionCollection Detail:

 public  void add(Permission permission) {
        if (isReadOnly())
            throw new SecurityException("attempt to add a Permission to " +
                                        "a readonly PermissionCollection");
        if (permission != CryptoAllPermission.INSTANCE)
            return;
        all_allowed = true;
}

Adds a permission to the CryptoAllPermissions.

 public Enumeration elements() {
        Vector v = new Vector(1);
        if (all_allowed) v.add(CryptoAllPermission.INSTANCE);
        return v.elements();
}

Returns an enumeration of all the CryptoAllPermission objects in the container.

 public boolean implies(Permission permission) {
        if (!(permission instanceof CryptoPermission)) {
            return false;
        }
        return all_allowed;
}

Check and see if this set of permissions implies the permissions expressed in "permission".
