public BasicPermission(String name) 
{
        super(name);
        init(name);
}

Creates a new BasicPermission with the specified name. Name is the symbolic name of the permission, such as "setFactory", "print.queueJob", or "topLevelWindow", etc.

Parameters:

name - the name of the BasicPermission.

Throws:

NullPointerException - if name is null.

IllegalArgumentException - if name is empty.

 public BasicPermission(String name,
    String actions) 
{
        super(name);
        init(name);
}

Creates a new BasicPermission object with the specified name. The name is the symbolic name of the BasicPermission, and the actions String is currently unused.

Parameters:

name - the name of the BasicPermission.

actions - ignored.

Throws:

NullPointerException - if name is null.

IllegalArgumentException - if name is empty.

 public boolean equals(Object obj) 
{
        if (obj == this)
            return true;
        if ((obj == null) || (obj.getClass() != getClass()))
            return false;
        BasicPermission bp = (BasicPermission) obj;
        return getName().equals(bp.getName());
}

Checks two BasicPermission objects for equality. Checks that obj's class is the same as this object's class and has the same name as this object.

 public String getActions() 
{
        return "";
}

Returns the canonical string representation of the actions, which currently is the empty string "", since there are no actions for a BasicPermission.

 final String getCanonicalName() 
{
        return exitVM ? "exitVM.*" : getName();
}

Returns the canonical name of this BasicPermission. All internal invocations of getName should invoke this method, so that the pre-JDK 1.6 "exitVM" and current "exitVM.*" permission are equivalent in equals/hashCode methods.

 public int hashCode() 
{
        return this.getName().hashCode();
}

Returns the hash code value for this object. The hash code used is the hash code of the name, that is, getName().hashCode(), where getName is from the Permission superclass.

 public boolean implies(Permission p) 
{
        if ((p == null) || (p.getClass() != getClass()))
            return false;
        BasicPermission that = (BasicPermission) p;
        if (this.wildcard) {
            if (that.wildcard) {
                // one wildcard can imply another
                return that.path.startsWith(path);
            } else {
                // make sure ap.path is longer so a.b.* doesn't imply a.b
                return (that.path.length()  > this.path.length()) &&
                    that.path.startsWith(this.path);
            }
        } else {
            if (that.wildcard) {
                // a non-wildcard can't imply a wildcard
                return false;
            }
            else {
                return this.path.equals(that.path);
            }
        }
}

Checks if the specified permission is "implied" by this object.

More specifically, this method returns true if:

• p's class is the same as this object's class, and

• p's name equals or (in the case of wildcards) is implied by this object's name. For example, "a.b.*" implies "a.b.c".

 public PermissionCollection newPermissionCollection() 
{
        return new BasicPermissionCollection(this.getClass());
}

Returns a new PermissionCollection object for storing BasicPermission objects.

BasicPermission objects must be stored in a manner that allows them to be inserted in any order, but that also enables the PermissionCollection implies method to be implemented in an efficient (and consistent) manner.
