Class Type.SchemalessStruct (2.42.0) 

public abstract static class Type.SchemalessStruct implements Type, SqlType.Struct

This is a special version of struct that is intended to only be used in the com.google.cloud.bigtable.data.v2.models.sql.StructReader getters that require types. We don't want users to need to specify the struct schema when the schema will be validated on calls to com.google.cloud.bigtable.data.v2.models.sql.StructReader methods on the struct.

Any attempts to interact with the schema will throw an exception.

For example the historical map data type uses this as follows:


 Map<ByteString, List<Struct>> historicalMap =
     resultSet.getMap(
        "cf",
        SqlType.mapOf(SqlType.bytes(), SqlType.arrayOf(SqlType.struct())));
 Struct struct = historicalMap.get("column").get(0);
 // Struct schema will be validated here so there's no need for users to pass the schema to getMap above
 ByteString value = struct.getBytes("value");
