----------------------------------
Summary: Allow declaration of namespace within script
Key: JEXL-333
URL: https://issues.apache.org/jira/browse/JEXL-333
Project: Commons JEXL
Issue Type: Improvement
Affects Versions: 3.1
Reporter: Henri Biestro
Assignee: Henri Biestro
Fix For: 3.2
WHAT:
Allow declaration of a namespace within a script.
WHY:
As of 3.1, namespaces must be declared at Jexl engine building time. With an
external (properties) configuration, adding new namespaces requires rebuilding
the engine or updating the namespace map. This is often inconvenient in test or
dev scenarios.
HOW:
Using a pragma, it is possible to statically add namespace entries for valid
for the duration of the script execution. The options vehicle can be reused.
The syntax will be:
{code}#pragma jexl.namespace.xyz f.q.c.n{code}
Where xyz is the actual namespace prefix and 'f.q.c.n.' the fully qualified
class name.
