Package com.kenshoo.pl.entity.equalityfunctions

Class ComparableEqualityFunction<T extends java.lang.Comparable<? super T>>

  • All Implemented Interfaces:
    EntityValueEqualityFunction<T>, java.util.function.BiFunction<T,​T,​java.lang.Boolean>
    public class ComparableEqualityFunction<T extends java.lang.Comparable<? super T>>
extends java.lang.Object
implements EntityValueEqualityFunction<T>
    This Function overrides the default Bid Field comparison of using equals() with compare(). It is needed because BigDecimals' equals() takes into account the number's scale, which means
    0.0 != 0.00
    This can cause strange behaviours, especially when comparing UI values against DB values.
    Using compare() instead solves this problem as it ignores scale when the values are the same.
