Constructor Detail

Show

public Show(String id)

This method constructs the request to get the detail for a specific image.

This method was using HEAD in the past and has been changed to use GET. In order to use GET, the mapping of the returned entity has to be specially handled (it is an unwrapped json object).

Parameters:

id - The id of the image to show

Method Detail

execute

public Image execute()
              throws OpenStackConnectException,
                     OpenStackResponseException

We have to override the parsing of the returned entity here because it comes back to us as an unwrapped json object (i.e., there is no root class name). In order to do that, we have to intercept the response entity processing, get the content as a generic JsonNode, and then map it ourself after setting the Jackson object mapper to handle unwrapped objects.

Overrides:

execute in class OpenStackRequest<Image>

Throws:

OpenStackConnectException

OpenStackResponseException
