Usage

From source file:org.jdbcluster.JDBClusterUtil.java

/**
 * Tries to determine the best fitting method for a set of parameter types.
 * Uses getMethod() first, if there is no direct match every parameter is
 * checked if there is a method with a superclass or superinterface match.
 * etc. For this best fitting method a scoring is used. It counts for every
 * parameter the "distance" from the class to the requested superclass or
 * superinterface. These "distances" are cummulated to one value. The method
 * with the lowest scoring value is returned.
 * /* w w w . j  a  va 2 s.  c  om*/
