Example 7 with SortDescriptor

Example 8 with SortDescriptor

use of io.realm.internal.SortDescriptor in project realm-java by realm.

the class RealmQuery method findAllSorted.

/**
     * Finds all objects that fulfill the query conditions and sorted by specific field name.
     * <p>
     * Sorting is currently limited to character sets in 'Latin Basic', 'Latin Supplement', 'Latin Extended A',
     * 'Latin Extended B' (UTF-8 range 0-591). For other character sets, sorting will have no effect.
     *
     * @param fieldName the field name to sort by.
     * @param sortOrder how to sort the results.
     * @return a {@link io.realm.RealmResults} containing objects. If no objects match the condition, a list with zero
     * objects is returned.
     * @throws java.lang.IllegalArgumentException if field name does not exist or it belongs to a child
     * {@link RealmObject} or a child {@link RealmList}.

Example 9 with SortDescriptor

use of io.realm.internal.SortDescriptor in project realm-java by realm.

the class RealmQuery method findAllSortedAsync.

/**
     * Similar to {@link #findAllSorted(String, Sort)} but runs asynchronously on a worker thread
     * (need a Realm opened from a looper thread to work).
     *
     * @return immediately an empty {@link RealmResults}. Users need to register a listener
     *         {@link io.realm.RealmResults#addChangeListener(RealmChangeListener)} to be notified when the query completes.
     * @throws java.lang.IllegalArgumentException if field name does not exist or it belongs to a child
     * {@link RealmObject} or a child {@link RealmList}.

Example 10 with SortDescriptor

use of io.realm.internal.SortDescriptor in project realm-java by realm.

the class RealmQuery method distinct.

/**
     * Returns a distinct set of objects of a specific class. If the result is sorted, the first
     * object will be returned in case of multiple occurrences, otherwise it is undefined which
     * object is returned.
     *
     * @param fieldName the field name.
     * @return a non-null {@link RealmResults} containing the distinct objects.
     * @throws IllegalArgumentException if a field is {@code null}, does not exist, is an unsupported type,
     * is not indexed, or points to linked fields.
