com.clickhouse.data.ClickHouseByteBuffer
All Implemented Interfaces:
Serializable
@Deprecated public final class ClickHouseByteBuffer extends Object implements Serializable
Deprecated.
This class represents a slice of a byte array. It holds a reference to a byte array, and it uses position() and length() to define the slice. You may think of it as a lite version of ByteBuffer.
