    public class PolicySecurityController
    extends SecurityController

A security controller relying on Java `Policy` in effect. When you use this security controller, your securityDomain objects must be instances of `CodeSource` representing the location from where you load your scripts. Any Java policy "grant" statements matching the URL and certificate in code sources will apply to the scripts. If you specify any certificates within your `CodeSource` objects, it is your responsibility to verify (or not) that the script source files are signed in whatever implementation-specific way you're using.

Methods

`java.lang.Object`

`callWithDomain(java.lang.Object securityDomain, Context cx, Callable callable, Scriptable scope, Scriptable thisObj, java.lang.Object[] args)`
Call `Callable.call(Context cx, Scriptable scope, Scriptable thisObj, Object[] args)` of callable under restricted security domain where an action is allowed only if it is allowed according to the Java stack on the moment of the execWithDomain call and securityDomain.

`GeneratedClassLoader` `createClassLoader(java.lang.ClassLoader parent, java.lang.Object securityDomain)` Get class loader-like object that can be used to define classes with the given security context.
`java.lang.Object` `getDynamicSecurityDomain(java.lang.Object securityDomain)` Get dynamic security domain that allows an action only if it is allowed by the current Java stack and securityDomain.
`java.lang.Class<?>` `getStaticSecurityDomainClassInternal()`

### Method Detail

#### getStaticSecurityDomainClassInternal

    public java.lang.Class<?> getStaticSecurityDomainClassInternal()

Overrides:
  `getStaticSecurityDomainClassInternal` in class `SecurityController`

#### createClassLoader

    public GeneratedClassLoader createClassLoader(java.lang.ClassLoader parent,
                                         java.lang.Object securityDomain)

Description copied from class: `SecurityController`
Get class loader-like object that can be used to define classes with the given security context.

Specified by:
  `createClassLoader` in class `SecurityController`
Parameters:
  `parent` - parent class loader to delegate search for classes not defined by the class loader itself
  `securityDomain` - some object specifying the security context of the code that is defined by the returned class loader.

#### getDynamicSecurityDomain

    public java.lang.Object getDynamicSecurityDomain(java.lang.Object securityDomain)

Description copied from class: `SecurityController`
Get dynamic security domain that allows an action only if it is allowed by the current Java stack and securityDomain. If securityDomain is null, return domain representing permissions allowed by the current stack.

Specified by:
  `getDynamicSecurityDomain` in class `SecurityController`

#### callWithDomain

    public java.lang.Object callWithDomain(java.lang.Object securityDomain,
                                  Context cx,
                                  Callable callable,
                                  Scriptable scope,
                                  Scriptable thisObj,
                                  java.lang.Object[] args)

Description copied from class: `SecurityController`
Call `Callable.call(Context cx, Scriptable scope, Scriptable thisObj, Object[] args)` of callable under restricted security domain where an action is allowed only if it is allowed according to the Java stack on the moment of the execWithDomain call and securityDomain. Any call to `SecurityController.getDynamicSecurityDomain(Object)` during execution of `callable.call(cx, scope, thisObj, args)` should return a domain incorporate restrictions imposed by securityDomain and Java stack on the moment of callWithDomain invocation.

The method should always be overridden, it is not declared abstract for compatibility reasons.

Overrides:
  `callWithDomain` in class `SecurityController`
