Class NumericConditionOperator

java.lang.Object

de.tsl2.nano.util.parser.Parser<INPUT>

de.tsl2.nano.util.operation.Operator<CharSequence,T>

de.tsl2.nano.util.operation.SOperator<T>

de.tsl2.nano.util.operation.ConditionOperator<Object>

de.tsl2.nano.util.operation.NumericConditionOperator

All Implemented Interfaces:

IParser<CharSequence>

public class NumericConditionOperator
extends ConditionOperator<Object>

Combination of conditioning (including booleans) and numeric operator. result has to be of type BigDecimal. This implementation disables type generics of super classes. uses Function to calculate inside functions before.
