Method Details

compare

public int compare(Constructor<?> o1,
 Constructor<?> o2)

Specified by:

compare in interface Comparator<Constructor<?>>

matchRank

public ArgsComparator.MATCHRANK matchRank(Constructor<?> ctor,
 Object[] arguments)

Establish a priority value (lower is better) based on how well the arguments match to the given constructor's parameters. Note: The distinction between primitives and boxed types is lost here, as the primitive version of Classinvalid input: '<'?> is only accessible via Long.TYPE and similar, so primitive matching and auto-boxed matching are effectively the same rank. rank 0 -> all arguments are the same type or boxed type rank 1 -> all arguments are assignable, without autoboxing rank 2 -> all arguments are assignable, with autoboxing rank 3 -> not all arguments are assignable

Parameters:

ctor - - constructor

arguments - - arguments to match against

Returns:

a lower number for when arguments match parameters better
