- Method Detail
  - getEndpoints
```
public final Collection<E> getEndpoints()
```
    Description copied from interface: EndpointsSupplier
    Return the provided endpoints.
    Specified by:
    getEndpoints in interface EndpointsSupplier<E extends ExposableEndpoint<O>>
    Returns:
    the endpoints
  - isExtensionExposed
```
protected boolean isExtensionExposed(Object extensionBean)
```
    Determine if an extension bean should be exposed. Subclasses can override this method to provide additional logic.
    Parameters:
    extensionBean - the extension bean
    Returns:
    true if the extension is exposed
  - isEndpointExposed
```
protected boolean isEndpointExposed(Object endpointBean)
```
    Determine if an endpoint bean should be exposed. Subclasses can override this method to provide additional logic.
    Parameters:
    endpointBean - the endpoint bean
    Returns:
    true if the endpoint is exposed
  - getEndpointType
```
protected Class<? extends E> getEndpointType()
```
  - createEndpoint
```
protected abstract E createEndpoint(Object endpointBean,
                                    EndpointId id,
                                    boolean enabledByDefault,
                                    Collection<O> operations)
```
    Factory method called to create the endpoint.
    Parameters:
    endpointBean - the source endpoint bean
    id - the ID of the endpoint
    enabledByDefault - if the endpoint is enabled by default
    operations - the endpoint operations
    Returns:
    a created endpoint (a DiscoveredEndpoint is recommended)
  - createOperation
```
protected abstract O createOperation(EndpointId endpointId,
                                     DiscoveredOperationMethod operationMethod,
                                     OperationInvoker invoker)
```
    Factory method to create an endpoint operation.
    Parameters:
    endpointId - the endpoint id
    operationMethod - the operation method
    invoker - the invoker to use
    Returns:
