Detailed Description
This class adapts a Comparator able to compare bean objects, to a Comparator able to compare nodes based on those bean objects.
The nodes will be sorted as the underlying bean objects are sorted by the bean comparator passed in the constructor of this object.
A typical use of the BeanComparatorAdapter will be inside a ChildrenManager. The method getComparator() must return a Comparator that compares nodes. But as a user you may prefer to compare at the bean level as each node represents a given bean. You can therefore write a Comparator that compares your beans and use the BeanComparatorAdapter to return a node Comparator based on your bean Comparator :
public Comparator getComparator() {
return new BeanComparatorAdapter(new MyBeanComparator());
}
In this example, MyBeanComparator is a class that you write to compare the beans that are used to create the node. MyBeanComparator only knows how to compare two bean objects, instead of comparing two nodes based on those bean objects.
