Examples with SplittablePayloadBsonWriter com.mongodb.internal.connection.SplittablePayloadBsonWriter used on opensource projects

Example 1 with SplittablePayloadBsonWriter

use of com.mongodb.internal.connection.SplittablePayloadBsonWriter in project mongo-java-driver by mongodb.

the class CryptConnection method command.

@Override
public <T> T command(final String database, final BsonDocument command, final FieldNameValidator commandFieldNameValidator, final ReadPreference readPreference, final Decoder<T> commandResultDecoder, final SessionContext sessionContext, @Nullable final ServerApi serverApi, final RequestContext requestContext, final boolean responseExpected, @Nullable final SplittablePayload payload, @Nullable final FieldNameValidator payloadFieldNameValidator) {
    if (serverIsLessThanVersionFourDotTwo(wrapped.getDescription())) {
        throw new MongoClientException("Auto-encryption requires a minimum MongoDB version of 4.2");
    }
    BasicOutputBuffer bsonOutput = new BasicOutputBuffer();
    BsonBinaryWriter bsonBinaryWriter = new BsonBinaryWriter(new BsonWriterSettings(), new BsonBinaryWriterSettings(getDescription().getMaxDocumentSize()), bsonOutput, getFieldNameValidator(payload, commandFieldNameValidator, payloadFieldNameValidator));
    BsonWriter writer = payload == null ? bsonBinaryWriter : new SplittablePayloadBsonWriter(bsonBinaryWriter, bsonOutput, createSplittablePayloadMessageSettings(), payload, MAX_SPLITTABLE_DOCUMENT_SIZE);
    getEncoder(command).encode(writer, command, EncoderContext.builder().build());
    RawBsonDocument encryptedCommand = crypt.encrypt(database, new RawBsonDocument(bsonOutput.getInternalBuffer(), 0, bsonOutput.getSize()));
    RawBsonDocument encryptedResponse = wrapped.command(database, encryptedCommand, commandFieldNameValidator, readPreference, new RawBsonDocumentCodec(), sessionContext, serverApi, requestContext, responseExpected, null, null);
    RawBsonDocument decryptedResponse = crypt.decrypt(encryptedResponse);
    BsonBinaryReader reader = new BsonBinaryReader(decryptedResponse.getByteBuffer().asNIO());
    return commandResultDecoder.decode(reader, DecoderContext.builder().build());
}

Example 2 with SplittablePayloadBsonWriter

use of com.mongodb.internal.connection.SplittablePayloadBsonWriter in project mongo-java-driver by mongodb.

the class CryptConnection method commandAsync.

@Override
public <T> void commandAsync(final String database, final BsonDocument command, final FieldNameValidator commandFieldNameValidator, final ReadPreference readPreference, final Decoder<T> commandResultDecoder, final SessionContext sessionContext, final ServerApi serverApi, final RequestContext requestContext, final boolean responseExpected, @Nullable final SplittablePayload payload, @Nullable final FieldNameValidator payloadFieldNameValidator, final SingleResultCallback<T> callback) {
    if (serverIsLessThanVersionFourDotTwo(wrapped.getDescription())) {
        callback.onResult(null, new MongoClientException("Auto-encryption requires a minimum MongoDB version of 4.2"));
        return;
    }
    try {
        BasicOutputBuffer bsonOutput = new BasicOutputBuffer();
        BsonBinaryWriter bsonBinaryWriter = new BsonBinaryWriter(new BsonWriterSettings(), new BsonBinaryWriterSettings(getDescription().getMaxDocumentSize()), bsonOutput, getFieldNameValidator(payload, commandFieldNameValidator, payloadFieldNameValidator));
        BsonWriter writer = payload == null ? bsonBinaryWriter : new SplittablePayloadBsonWriter(bsonBinaryWriter, bsonOutput, createSplittablePayloadMessageSettings(), payload, MAX_SPLITTABLE_DOCUMENT_SIZE);
        getEncoder(command).encode(writer, command, EncoderContext.builder().build());
        crypt.encrypt(database, new RawBsonDocument(bsonOutput.getInternalBuffer(), 0, bsonOutput.getSize())).flatMap((Function<RawBsonDocument, Mono<RawBsonDocument>>) encryptedCommand -> Mono.create(sink -> wrapped.commandAsync(database, encryptedCommand, commandFieldNameValidator, readPreference, new RawBsonDocumentCodec(), sessionContext, serverApi, requestContext, responseExpected, null, null, sinkToCallback(sink)))).flatMap(crypt::decrypt).map(decryptedResponse -> commandResultDecoder.decode(new BsonBinaryReader(decryptedResponse.getByteBuffer().asNIO()), DecoderContext.builder().build())).subscribe(decryptedResult -> callback.onResult(decryptedResult, null), e -> callback.onResult(null, e));
    } catch (Throwable t) {
        callback.onResult(null, t);
    }
