Class MinFunctionStateObject

  • All Implemented Interfaces:
    StateObject

    public class MinFunctionStateObject
    extends AggregateFunctionStateObject
    One of the aggregate functions. The arguments must correspond to orderable state-field types (i.e., numeric types, string types, character types, or date types). The return type of this function is based on the state-field's type.
