<div class="block">This basic function of this class is to return a Method
object for a particular class given the name of a method
and the parameters to the method in the form of an Object[]
The first time the Introspector sees a
class it creates a class method map for the
class in question. Basically the class method map
is a Hashtable where Method objects are keyed by a
concatenation of the method name and the names of
classes that make up the parameters.
For example, a method with the following signature:
public void method(String a, StringBuffer b)
would be mapped by the key:
"method" + "java.lang.String" + "java.lang.StringBuffer"
This mapping is performed for all the methods in a class
and stored for</div>
