the class ValuesHelper method encodeValues.

Example 2 with Murmur3Token

use of com.datastax.oss.driver.internal.core.metadata.token.Murmur3Token in project java-driver by datastax.

the class ValuesHelper method encodePreparedValues.

public static ByteBuffer[] encodePreparedValues(Object[] values, ColumnDefinitions variableDefinitions, CodecRegistry codecRegistry, ProtocolVersion protocolVersion) {
    // Almost same as encodeValues, but we can't reuse because of variableDefinitions. Rebuilding a
    // list of datatypes is not worth it, so duplicate the code.
