      • isSorted

        public DoubleArrayAssert isSorted()
        Verifies that the actual array is sorted into ascending order according to the natural ordering of its elements.

        All array elements must be primitive or implement the Comparable interface and must be mutually comparable (that is, e1.compareTo(e2) must not throw a ClassCastException for any elements e1 and e2 in the array), examples :

        • a array composed of {2, 4, 6} is ok because the element type is a primitive type.
        • a array composed of {"a1", "a2", "a3"} is ok because the element type (String) is Comparable
        • a array composed of Rectangle {r1, r2, r3} is NOT ok because Rectangle is not Comparable
        • a array composed of {True, "abc", False} is NOT ok because elements are not mutually comparable (even though each element type implements Comparable)
        Empty or one element arrays are considered sorted (unless the array element type is not Comparable).

        Specified by:
        isSorted in interface ArraySortedAssert<DoubleArrayAssert,​java.lang.Double>
        Returns:
        this assertion object.

      • isSortedAccordingTo

        public DoubleArrayAssert isSortedAccordingTo​(java.util.Comparator<? super java.lang.Double> comparator)
        Verifies that the actual array is sorted according to the given comparator.
        Empty arrays are considered sorted whatever the comparator is.
        One element arrays are considered sorted if element is compatible with comparator, otherwise an AssertionError is thrown.
        Specified by:
        isSortedAccordingTo in interface ArraySortedAssert<DoubleArrayAssert,​java.lang.Double>
        Parameters:
        comparator - the Comparator used to compare array elements
        Returns:
        this assertion object.

      • usingElementComparator

        public DoubleArrayAssert usingElementComparator​(java.util.Comparator<? super java.lang.Double> customComparator)
        Use given custom comparator instead of relying on actual type A equals method to compare group elements for incoming assertion checks.

        Custom comparator is bound to assertion instance, meaning that if a new assertion is created, it will use default comparison strategy.

        Examples : 

         // compares invoices by payee 
 assertThat(invoiceList).usingComparator(invoicePayeeComparator).isEqualTo(expectedInvoiceList).
 
 // compares invoices by date, doesNotHaveDuplicates and contains both use the given invoice date comparator
 assertThat(invoiceList).usingComparator(invoiceDateComparator).doesNotHaveDuplicates().contains(may2010Invoice)
 
 // as assertThat(invoiceList) creates a new assertion, it falls back to standard comparison strategy 
 // based on Invoice's equal method to compare invoiceList elements to lowestInvoice.                                                      
 assertThat(invoiceList).contains(lowestInvoice).
 
 // standard comparison : the fellowshipOfTheRing includes Gandalf but not Sauron (believe me) ...
 assertThat(fellowshipOfTheRing).contains(gandalf)
                                .doesNotContain(sauron);
 
 // ... but if we compare only races, Sauron is in fellowshipOfTheRing because he's a Maia like Gandalf.
 assertThat(fellowshipOfTheRing).usingElementComparator(raceComparator)
                                .contains(sauron);
        Specified by:
        usingElementComparator in interface EnumerableAssert<DoubleArrayAssert,​java.lang.Double>
        Parameters:
        customComparator - the comparator to use for incoming assertion checks.
        Returns:
        this assertion object.
