Class AbsExpressionStateObject

  • All Implemented Interfaces:
    StateObject
    public class AbsExpressionStateObject
extends AbstractSingleEncapsulatedExpressionStateObject
    The ABS function removes the minus sign from a specified argument and returns the absolute value, which is always a positive number or zero.

    This is one of the JPQL arithmetic functions. The ABS function takes a numeric argument and returns a number (integer, float, or double) of the same type as the argument to the function.
