Class BeanUtils

java.lang.Object
  de.schwarzrot.bean.BeanUtils

public class BeanUtils
extends Object

helper class to handle JavaBeans. As standard java classes don't handle interfaces and generics right away, I had to implement my own variant.

Method Detail

determineGetter

public Method determineGetter(Class<?> beanType,
                              String propertyName)

determines the getter matching the given property name

Parameters:

beanType - - the class of the bean

propertyName - - the name of the property

Returns:

- the getter to access the property values

determineProperties

public Map<String,PropertyInfo> determineProperties(Class entityType)

scans the properties of a bean in a slightly different way, that the java standard introspection. Whereas the latter prefers interfaces instead of derived classes it is vital for our persistence layer to know about the derived classes.

Generics are welcome, but not always that usable, especially if you try to implement type overloading at persistence level.

Parameters:

entityType - - the type that should get investigated

Returns:

- a map that holds property info

dumpClass

protected void dumpClass(Class<?> c)
