Description
A number of extensions to the JMX Query API are under consideration for its version 2.0, being defined by JSR 255.  Among these are:

- Define a query language and provide methods to convert strings in this language into QueryExp objects and vice versa.

- Define a way to get the string representation (String.valueOf) of an arbitrary attribute inside a query.  Currently only attributes of type Number, String, or Boolean can figure in queries.

- Allow attribute names inside queries to contain a dot, to extract a value from within a complex attribute, as is already done in the Monitor API.
Comments
EVALUATION For the moment we are not planning to add the "attribute as string" feature. The main use case for this was ObjectName attributes, but the ability to access properties using dot syntax means that you can write objectNameAttr.canonicalName to access the ObjectName as a string via ObjectName.getCanonicalName(). The other items are still planned as described.

EVALUATION A relatively small but powerful set of extensions.
