Subject [jira] Created: (BEANUTILS-376) Supporting indexed (mapped) properties of Map objects
Date Wed, 02 Jun 2010 14:25:38 GMT
Supporting indexed (mapped) properties of Map objects

                 Key: BEANUTILS-376
             Project: Commons BeanUtils
          Issue Type: Improvement
          Components: Bean / Property Utils
         Environment: JDK1.5_22, WinXP
            Reporter: Zdeněk Obst
            Priority: Minor

So far, BeanUtils does not support indexed or mapped properties of Map object (PropertyUtilsBean.getPropertyOfMapBean(Map
bean, String propertyName) )
and throw IllegalArgumentException.

For instance if you have Map<String, String[]> and you want to get property by calling
propName[0] (or propName(0)), method isIndexed (isMapped) of DefaultResolver returns true
which raises previously mentioned exception. From my point of view it seems that method gets
data which needs and is possible to parse propertyName to get desired result.

E.g. something similar to:
if  (resolver.isIndexed(propertyName)) {
   String name = resolver.getProperty(propertyName);
   int idx = Integer.valueOf(resolver.getIndex(propertyName)); // handle NumberFormat exception
by your way
   return bean.get(name)[idx]; // handle ArrayIndexOutOfBounds exception by your way

I was a bit surprised that I didn't find this issue in existing ones. I'm sorry if there is
any which I omitted. 
Is it possible that this funcionality will be provided in any future release? Thank you
