com.google.cloud.spanner.AbstractStructReader

com.google.cloud.spanner.Struct

All Implemented Interfaces:

StructReader, Serializable

@Immutable
public abstract class Struct
extends AbstractStructReader
implements Serializable

Represents a value of Type.Code.STRUCT. Such values are a tuple of named and typed columns, where individual columns may be null. Individual rows from a read or query operation can be considered as structs; ResultSet.getCurrentRowAsStruct() allows an immutable struct to be created from the row that the result set is currently positioned over.

Struct instances are immutable.
