Examples with ParseContext com.google.firebase.firestore.core.UserData.ParseContext used on opensource projects

Example 1 with ParseContext

use of com.google.firebase.firestore.core.UserData.ParseContext in project firebase-android-sdk by firebase.

the class UserDataReader method parseUpdateData.

/**
 * Parse update data from an {@code update()} call.
 */
public ParsedUpdateData parseUpdateData(Map<String, Object> data) {
    checkNotNull(data, "Provided update data must not be null.");
    ParseAccumulator accumulator = new ParseAccumulator(UserData.Source.Update);
    ParseContext context = accumulator.rootContext();
    ObjectValue updateData = new ObjectValue();
    for (Entry<String, Object> entry : data.entrySet()) {
        FieldPath fieldPath = com.google.firebase.firestore.FieldPath.fromDotSeparatedPath(entry.getKey()).getInternalPath();
        Object fieldValue = entry.getValue();
        if (fieldValue instanceof DeleteFieldValue) {
            // Add it to the field mask, but don't add anything to updateData.
            context.addToFieldMask(fieldPath);
        } else {
            @Nullable Value parsedValue = convertAndParseFieldData(fieldValue, context.childContext(fieldPath));
            if (parsedValue != null) {
                context.addToFieldMask(fieldPath);
                updateData.set(fieldPath, parsedValue);
            }
        }
    }
    return accumulator.toUpdateData(updateData);
}

Example 2 with ParseContext

use of com.google.firebase.firestore.core.UserData.ParseContext in project firebase-android-sdk by firebase.

the class UserDataReader method parseArrayTransformElements.

private List<Value> parseArrayTransformElements(List<Object> elements) {
    ParseAccumulator accumulator = new ParseAccumulator(UserData.Source.Argument);
    List<Value> result = new ArrayList<>(elements.size());
    for (int i = 0; i < elements.size(); i++) {
        Object element = elements.get(i);
        // Although array transforms are used with writes, the actual elements
        // being unioned or removed are not considered writes since they cannot
        // contain any FieldValue sentinels, etc.
        ParseContext context = accumulator.rootContext();
        result.add(convertAndParseFieldData(element, context.childContext(i)));
    }
    return result;
}

Example 3 with ParseContext

use of com.google.firebase.firestore.core.UserData.ParseContext in project firebase-android-sdk by firebase.

the class UserDataReader method parseUpdateData.

/**
 * Parses the update data from the update(field, value, field, value...) varargs call, accepting
 * both strings and FieldPaths.
 */

    // fieldsAndValues.length and alternating types should already be validated by
    // Util.collectUpdateArguments().
    hardAssert(fieldsAndValues.size() % 2 == 0, "Expected fieldAndValues to contain an even number of elements");
    ParseAccumulator accumulator = new ParseAccumulator(UserData.Source.Update);
    ParseContext context = accumulator.rootContext();
    ObjectValue updateData = new ObjectValue();
    Iterator<Object> iterator = fieldsAndValues.iterator();
    while (iterator.hasNext()) {
        Object fieldPath = iterator.next();
        Object fieldValue = iterator.next();
        hardAssert(fieldPath instanceof String || fieldPath instanceof com.google.firebase.firestore.FieldPath, "Expected argument to be String or FieldPath.");
        FieldPath parsedField;
        if (fieldPath instanceof String) {
            parsedField = com.google.firebase.firestore.FieldPath.fromDotSeparatedPath((String) fieldPath).getInternalPath();
        } else {
            parsedField = ((com.google.firebase.firestore.FieldPath) fieldPath).getInternalPath();
        }
        if (fieldValue instanceof DeleteFieldValue) {
            // Add it to the field mask, but don't add anything to updateData.
            context.addToFieldMask(parsedField);

            Value parsedValue = convertAndParseFieldData(fieldValue, context.childContext(parsedField));
            if (parsedValue != null) {
                context.addToFieldMask(parsedField);
                updateData.set(parsedField, parsedValue);
            }
