countArgs

public static int countArgs(String descriptor)

countArgs

protected static int countArgs(String descriptor,
 int widthOfLongsAndDoubles)

Count the number of arguments in the descriptor. Each long or double counts as widthOfLongsAndDoubles; all other arguments count as 1.

Parameters:

descriptor - String for which arguments are counted

widthOfLongsAndDoubles - int increment to apply for longs doubles. This is typically 1 when counting arguments alone, or 2 when counting arguments for invokeinterface.

Returns:

integer count
