Notes on the Saxon implementation
Saxon implements the zero-argument function by passing a null URI to the registered
CollectionURIResolver
. The default CollectionURIResolver
implementation supplied with the product handles this by returning an empty sequence, but
a user-supplied CollectionURIResolver
is free to handle this case any way it
wishes.
If a user-defined CollectionURIResolver
has been registered, the action of
this function is entirely user-defined. A resolver may be registered using the
setCollectionResolver()
method on the Configuration object, or (in XSLT) using
setAttribute()
on the TransformerFactory
. The
CollectionURIResolver
may also be nominated using the -cr
option on the command line.
For details of the behavior of the standard CollectionURIResolver
, see Collections.
The collection()
function is multi-threaded in Saxon-EE (since 9.5). Each
document in the collection is parsed in a separate thread, and the documents are processed
in the order in which parsing completes. This makes the order of the documents
unpredictable.
