org.tikv.common.types

类 BytesType

java.lang.Object

org.tikv.common.types.DataType

org.tikv.common.types.BytesType

所有已实现的接口:

Serializable

直接已知子类:

StringType

public class BytesType
extends DataType

TODO: if we need to unify string type and binary types? Indeed they are encoded as the same However, decode to string actually going through encoding/decoding by whatever charset.encoding format we set, and essentially changed underlying data
