[BeanUtils2] Implement possibility to find out if a property readable and/or
wirtable
-------------------------------------------------------------------------------------
Key: SANDBOX-387
URL: https://issues.apache.org/jira/browse/SANDBOX-387
Project: Commons Sandbox
Issue Type: Improvement
Components: BeanUtils2
Affects Versions: Nightly Builds
Reporter: Benedikt Ritter
Currently there is no possibility to find out, if a property is readable and/or
writable.
For example, one has to pass a value to
{{setProperty(name).withValue(argument)}} and hope, that the property is
writeable (because a {{NoSucheMethodExcpetion}} will be thrown, if it is not).
For this reason it would be nice, if one could do something like:
{code:java}
if (on(myBean).isWritable("writeableProperty") {
on(myBean).setProperty("writableProperty").withValue("This is a String
value!");
}
{code}
Solution:
* Add {{public boolean isWritable(String propertyName)}} and {{public boolean
isReadable(String propertyName)}} to {{BeanAccessor}}.
* in {{isWritable()}} check if a {{PropertyDescriptor}} can be obtained from
PropertyRegistry (if not, throw {{NoSuchMethodException}}).
** if so, return true, if {{propertyDescriptor.getWriteMethod() != null}} and
false otherwise.
* in {{isReadable()}} check if a {{PropertyDescriptor}} can be obtained from
PropertyRegistry (if not, throw {{NoSuchMethodException}}).
** if so, return true, if {{propertyDescriptor.getReadMethod() != null}} and
false otherwise.
