Dmitri Blinov created JEXL-222: ---------------------------------- Summary: The ability to declare indexed property getter/setter in customised JexlArithmetic implementation Key: JEXL-222 URL: https://issues.apache.org/jira/browse/JEXL-222 Project: Commons JEXL Issue Type: Improvement Affects Versions: 3.0 Reporter: Dmitri Blinov Priority: Minor
At the moment we have the ability to declare a specific getter/setter method in customized JexlArithmetic class that will be used by Jexl engine when engine tries to get access to a property of some object. This is great extension point of the Jexl but I have come to a situation where I need the same technics to be applied to indexed properties. For example I'm scripting org.w3c.dom.Element object by setting its attributes via its {code}Element.setAttribute(java.lang.String name, java.lang.String value) {code} method. In Jexl I use standard indexed property access syntax like the following: {code} node.attribute.id = "12345"; {code} The problem lies with the last argument of the setAttribute method which is of String class. And for Jexl standard indexed property setter to work I should always remember that in script I need to cast specified property value to a string, which is error-prone and lacks, in my understanding, scripting easiness. I see the solution as to introduce custom indexed property setter in more generalized form, accepting Object type as a value so it could cast a value to String before calling {{Element.setAttribute}} -- This message was sent by Atlassian JIRA (v6.3.15#6346)
