Method Detail

compareNullSafe

public static <T extends java.lang.Comparable<T>> int compareNullSafe(T object1,
                                                                      T object2)

Compares the two given objects. First checks if they are reference-equal. If not, checks each for null. If both are non-null, calls object1.compareTo(object2). null values will be ordered before non-null values.

compareNullSafe

public static <T> int compareNullSafe(T object1,
                                      T object2,
                                      java.util.Comparator<T> comparator)

Compares the two given objects. First checks if they are reference-equal. If not, checks each for null. If both are non-null, passes them to the given comparator. null values will be ordered before non-null values.

compareInOrder

public static int compareInOrder(java.util.function.IntSupplier... comparisonSuppliers)

Evaluates the given comparisons in order. If all of them evaluate to 0, returns 0, otherwise returns the first non-zero result.
