Examples with AtomicReferenceArrayElementComparisonStrategy org.assertj.core.internal.AtomicReferenceArrayElementComparisonStrategy used on opensource projects

Example 1 with AtomicReferenceArrayElementComparisonStrategy

use of org.assertj.core.internal.AtomicReferenceArrayElementComparisonStrategy in project assertj-core by joel-costigliola.

the class AtomicReferenceArrayAssert method usingElementComparator.

/**
 * Use given custom comparator instead of relying on actual element type <code>equals</code> method to compare AtomicReferenceArray
 * elements for incoming assertion checks.
 * <p>
 * Custom comparator is bound to assertion instance, meaning that if a new assertion is created, it will use default
 * comparison strategy.
 * <p>
 * Examples :
 * <pre><code class='java'> // compares invoices by payee
 * assertThat(invoiceArray).usingComparator(invoicePayeeComparator).isEqualTo(expectedinvoiceArray).
 *
 * // compares invoices by date, doesNotHaveDuplicates and contains both use the given invoice date comparator
 * assertThat(invoiceArray).usingComparator(invoiceDateComparator).doesNotHaveDuplicates().contains(may2010Invoice)
 *
 * // as assertThat(invoiceArray) creates a new assertion, it falls back to standard comparison strategy
 * // based on Invoice's equal method to compare invoiceArray elements to lowestInvoice.
 * assertThat(invoiceArray).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);</code></pre>
 *
 * @param elementComparator the comparator to use for incoming assertion checks.
 * @throws NullPointerException if the given comparator is {@code null}.
 * @return {@code this} assertion object.
