• scoreMatch

  public static int scoreMatch​(java.lang.Class[] javaParamTypes,

  Score the conversion of a set of XSLT arguments to a given set of Java parameters. If any invocations of this function for a method with the same name return the same positive value, then a conflict has occured, and an error should be signaled.

  Parameters:

  javaParamTypes - Must be filled with valid class names, and of the same length as xsltArgs.

  xsltArgs - Must be filled with valid object instances, and of the same length as javeParamTypes.

  Returns:

  -1 for no allowed conversion, or a positive score that is closer to zero for more preferred, or further from zero for less preferred.
