Examples with IndexEntry com.google.firebase.firestore.index.IndexEntry used on opensource projects

Example 1 with IndexEntry

use of com.google.firebase.firestore.index.IndexEntry in project firebase-android-sdk by firebase.

the class SQLiteIndexManager method computeIndexEntries.

/**
 * Creates the index entries for the given document.
 */
private SortedSet<IndexEntry> computeIndexEntries(Document document, FieldIndex fieldIndex) {
    SortedSet<IndexEntry> result = new TreeSet<>();
    @Nullable byte[] directionalValue = encodeDirectionalElements(fieldIndex, document);
    if (directionalValue == null) {
        return result;
    }
    @Nullable FieldIndex.Segment arraySegment = fieldIndex.getArraySegment();
    if (arraySegment != null) {
        Value value = document.getField(arraySegment.getFieldPath());
        if (isArray(value)) {
            for (Value arrayValue : value.getArrayValue().getValuesList()) {
                result.add(IndexEntry.create(fieldIndex.getIndexId(), document.getKey(), encodeSingleElement(arrayValue), directionalValue));
            }
        }
    } else {
        result.add(IndexEntry.create(fieldIndex.getIndexId(), document.getKey(), new byte[] {}, directionalValue));
    }
    return result;
}

Example 2 with IndexEntry

use of com.google.firebase.firestore.index.IndexEntry in project firebase-android-sdk by firebase.

the class SQLiteIndexManager method updateIndexEntries.

@Override
public void updateIndexEntries(ImmutableSortedMap<DocumentKey, Document> documents) {
    hardAssert(started, "IndexManager not started");
    for (Map.Entry<DocumentKey, Document> entry : documents) {
        Collection<FieldIndex> fieldIndexes = getFieldIndexes(entry.getKey().getCollectionGroup());
        for (FieldIndex fieldIndex : fieldIndexes) {
            SortedSet<IndexEntry> existingEntries = getExistingIndexEntries(entry.getKey(), fieldIndex);
            SortedSet<IndexEntry> newEntries = computeIndexEntries(entry.getValue(), fieldIndex);
            if (!existingEntries.equals(newEntries)) {
                updateEntries(entry.getValue(), existingEntries, newEntries);
            }
        }
    }
