Constructor Detail

### VMBridge_jdk13

    public VMBridge_jdk13()

Method Detail

### getThreadContextHelper

    protected java.lang.Object getThreadContextHelper()

  Description copied from class: `VMBridge`
  Return a helper object to optimize `Context` access.

  The runtime will pass the resulting helper object to the subsequent calls to `VMBridge.getContext(Object contextHelper)` and `VMBridge.setContext(Object contextHelper, Context cx)` methods. In this way the implementation can use the helper to cache information about current thread to make `Context` access faster.

  Specified by:
    `getThreadContextHelper` in class `VMBridge`

### getContext

    protected Context getContext(java.lang.Object contextHelper)

  Description copied from class: `VMBridge`
  Get `Context` instance associated with the current thread or null if none.

  Specified by:
    `getContext` in class `VMBridge`
  Parameters:
    `contextHelper` - The result of `VMBridge.getThreadContextHelper()` called from the current thread.

### setContext

    protected void setContext(java.lang.Object contextHelper,
                              Context cx)

  Description copied from class: `VMBridge`
  Associate `Context` instance with the current thread or remove the current association if `cx` is null.

  Specified by:
    `setContext` in class `VMBridge`
  Parameters:
    `contextHelper` - The result of `VMBridge.getThreadContextHelper()` called from the current thread.

### getCurrentThreadClassLoader

    protected java.lang.ClassLoader getCurrentThreadClassLoader()

  Description copied from class: `VMBridge`
  Return the ClassLoader instance associated with the current thread.

  Specified by:
    `getCurrentThreadClassLoader` in class `VMBridge`

### tryToMakeAccessible

    protected boolean tryToMakeAccessible(java.lang.Object accessibleObject)

  Description copied from class: `VMBridge`
  In many JVMSs, public methods in private classes are not accessible by default (Sun Bug #4071593). VMBridge instance should try to workaround that via, for example, calling method.setAccessible(true) when it is available. The implementation is responsible to catch all possible exceptions like SecurityException if the workaround is not available.

  Specified by:
    `tryToMakeAccessible` in class `VMBridge`
  Returns:
    true if it was possible to make method accessible or false otherwise.

### getInterfaceProxyHelper

    protected java.lang.Object getInterfaceProxyHelper(ContextFactory cf,
                                                       java.lang.Class<?>[] interfaces)

  Description copied from class: `VMBridge`
  Create helper object to create later proxies implementing the specified interfaces later. Under JDK 1.3 the implementation can look like:

       return java.lang.reflect.Proxy.getProxyClass(..., interfaces).
           getConstructor(new Class[] {
               java.lang.reflect.InvocationHandler.class });

  Overrides:
    `getInterfaceProxyHelper` in class `VMBridge`
    `interfaces` - Array with one or more interface class objects.

### newInterfaceProxy

    protected java.lang.Object newInterfaceProxy(java.lang.Object proxyHelper,
                                                 ContextFactory cf,
                                                 InterfaceAdapter adapter,
                                                 java.lang.Object target,
                                                 Scriptable topScope)

  Description copied from class: `VMBridge`
  Create proxy object for `InterfaceAdapter`. The proxy should call `InterfaceAdapter.invoke(ContextFactory cf, Object target, Scriptable topScope, Method method, Object[] args)` as implementation of interface methods associated with `proxyHelper`.

  Overrides:
    `newInterfaceProxy` in class `VMBridge`
  Parameters:
    `proxyHelper` - The result of the previous call to `VMBridge.getInterfaceProxyHelper(ContextFactory, Class[])`.

### isVarArgs

    protected boolean isVarArgs(java.lang.reflect.Member member)

  Description copied from class: `VMBridge`
  Returns whether or not a given member (method or constructor) has variable arguments. Variable argument methods have only been supported in Java since JDK 1.5.

  Specified by:
    `isVarArgs` in class `VMBridge`
