Function signature
$type |
xs:string |
Result |
xs:boolean |
Determines whether a type with a given name is available in the static context. The current implementation has a restriction: if the argument is known only at run-time, then the function tests whether the type exists in the run-time configuration, which does not necessarily prove that it was present in the static context.
In Saxon the type-available()
function can be used to check for the availability of Java classes. For example
type-available('jt:java.util.HashMap')
returns true, where the prefix jt
is bound to the URI
