Field Details

NULL_DEFINITION

public static final BigDecimal NULL_DEFINITION

It is the definition of Java null pointer for the rules language. Actually its value is 0 (rules variables are number) but we can use the null pointer and throws an NPE when a null value is used. I think this concept should not exist for those who writes the rules.
