Class SimpleConditionParser

java.lang.Object
  civquest.parser.condition.ConditionParser
      civquest.parser.condition.SimpleConditionParser

public class SimpleConditionParser

extends ConditionParser

A SimpleConditionParser can parse condition expressons with a maximum of two variables, h and t. This reduced flexibility leads to a faster evaluation process.

Note: To bind variables, please use the setH/setT methods, and to access their values, use getT/getH. This for higher efficiency.
