Parameters:

Returns:

the (deep-) link towards a javadoc page

Throws:

IllegalArgumentException - in case no javadoc link could be generated for the given reference

IllegalStateException - in case no javadoc source sites have been configured

createLink

public URI createLink(String binaryName)

Generates a (deep-)link to a HTML page in any of the sites given to the constructor. The link is not validated (i.e. might point to a non-existing page). Preferably resolves from the online sites if they provide the given package.
