Method Summary

All Methods Instance Methods Abstract Methods Default Methods
Modifier and Type	Method	Description
`ComponentInstance`	`createInstance()`	Create a new instance of this component.
`ComponentInstance`	`createInstance(Object instance)`
`Class<?>`	`getComponentClass()`	Get the component's actual implementation class.
`ComponentInstance`	`getInstance(Object instance)`	Returns a component instance for a pre-existing instance.
`NamespaceContextSelector`	`getNamespaceContextSelector()`
`default boolean`	`isRemotable(Throwable throwable)`	Checks whether the supplied `Throwable` is remotable meaning it can be safely sent to the client over the wire.
`void`	`start()`	Start operation called when the Component is available.
`void`	`stop()`	Stop operation called when the Component is no longer available.
`void`	`waitForComponentStart()`

- Method Detail
  - start
```
void start()
```
    Start operation called when the Component is available.
  - stop
```
void stop()
```
    Stop operation called when the Component is no longer available.
  - getComponentClass
```
Class<?> getComponentClass()
```
    Get the component's actual implementation class.
    
    Returns:
    
    the component class
  - createInstance
```
ComponentInstance createInstance()
```
    Create a new instance of this component. This may be invoked by a component interceptor, a client interceptor, or in the course of creating a new client, or in the case of an "eager" singleton, at component start. This method will block until the component is available. If the component fails to start then a runtime exception will be thrown.
    
    Returns:
    
    the component instance
  - createInstance
```
ComponentInstance createInstance(Object instance)
```
  - getInstance
```
ComponentInstance getInstance(Object instance)
```
    Returns a component instance for a pre-existing instance.
    
    Parameters:
    
    instance - the actual object instance
    
    Returns:
    
    a component instance
  - getNamespaceContextSelector
```
NamespaceContextSelector getNamespaceContextSelector()
```
  - isRemotable
```
default boolean isRemotable(Throwable throwable)
```
    Checks whether the supplied Throwable is remotable meaning it can be safely sent to the client over the wire.
  - waitForComponentStart
```
void waitForComponentStart()
```
