Method Detail

getFallbackEvaluationCost

public int getFallbackEvaluationCost()

Returns the cost of evaluation fallback binding values. when isApplicable() is true, this value is meaningless when isApplicable() is false, [1,Integer.MAX_VALUE-1] means a relative scale of cost, where cost c is better than cost c+k Integer.MAX_VALUE implies no match.

Returns:

cost of evaluating fallback values.
