Supporting indexed (mapped) properties of Map objects
-----------------------------------------------------
Key: BEANUTILS-376
URL: https://issues.apache.org/jira/browse/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
