findCloudProvider

protected CloudProvider findCloudProvider()
                                   throws javax.servlet.jsp.JspTagException

This method tries to find an ancestor object of type CloudTag in that case the first node provider found will be taken. REMARK: the CloudTag does not yet have 'id', i think. We dont' have multiple cloud support yet.

Returns:

the CloudTag if found, else an exception.

getCloud

protected Cloud getCloud()
                  throws javax.servlet.jsp.JspTagException

Find the CloudProvider and return its cloud variable in one step. And the result of findCloudProvider is stored, so invoking this function more often is better then invoking findCloudProvider every time.

Returns:

a Cloud

getCloudContext

protected CloudContext getCloudContext()

Returns:

the cloud context

getNode

public Node getNode(java.lang.String key)
             throws javax.servlet.jsp.JspTagException
