Examples with OperationTarget dev.morphia.query.OperationTarget used on opensource projects

Example 1 with OperationTarget

use of dev.morphia.query.OperationTarget in project morphia by mongodb.

the class Filter method getValue.

@Nullable
protected Object getValue(Datastore datastore) {
    if (!mapped) {
        PathTarget target = pathTarget(datastore.getMapper());
        OperationTarget operationTarget = new OperationTarget(pathTarget, value);
        this.value = operationTarget.getValue();
        PropertyModel property = target.getTarget();
        if (property != null && property.specializeCodec(datastore) instanceof PropertyHandler) {
            this.value = ((Document) operationTarget.encode(datastore)).get(field);
        }
        mapped = true;
    }
    return value;
}

Example 2 with OperationTarget

use of dev.morphia.query.OperationTarget in project morphia by mongodb.

the class PullOperator method toTarget.

@Override
public OperationTarget toTarget(PathTarget pathTarget) {
    return new OperationTarget(pathTarget, value()) {

        @Override
        public Object encode(Datastore datastore) {
            DocumentWriter writer = new DocumentWriter(datastore.getMapper());
            document(writer, () -> {
                ((Filter) getValue()).encode(datastore, writer, EncoderContext.builder().build());
            });
            return new Document(field(), writer.getDocument());
        }
    };
}
