[jira] [Updated] (JEXL-380) Multiple values per pragma key

["Henri Biestro (Jira)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/JEXL-380?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Henri Biestro updated JEXL-380:
-------------------------------
    Description: 
WHAT:

The same pragma key can be used multiple times in a script however only the last value remains. For instance,
{code:java}
#pragma stuff once
#pragma stuff twice{code}
Results in the pragma value for key 'stuff' being 'twice'. It can be desirable to retain all values for a key as a set (preserving creation order).

Incidentally, the getParsedText() script method should output the pragmas since they are quite necessary ro retain script functionality.

HOW:

The value of a pragma will become a set (LinkedHashSet) of objects as soon as more than one occurence of the key (and a different value) are used.

The debugger will get a new flag to output pragmas (false as a default, true when used through getParsedText()).
