Method Detail

setCloud

public void setCloud(java.lang.String c)

If there are more clouds to choose from, you can have a 'cloud' attribute in your tag, in wich you can indicate the id of the cloud you mean.

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.

getCloudProviderVar

protected Cloud getCloudProviderVar()
                             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
