Embedded Objects ORMLite 4.47

Question

Does ORMLite 4.47 support embedded objects? Getting an exception while trying to run a DAO test for an entity dao:

java.lang.IllegalArgumentException: ORMLite does not know how to store class com.abc.def.Pqr for field pqr. Use another class or a custom persister. at com.j256.ormlite.field.FieldType.(FieldType.java:189) at com.j256.ormlite.field.FieldType.createFieldType(FieldType.java:939)

@DatabaseTable(tableName = "XYZ")
public class Xyz
{
    @DatabaseField(columnName = "ID", canBeNull = false)
    private String id;

    @DatabaseField(columnName = "PQR")
    private Pqr pqr;

    ... 
}

@DatabaseTable(tableName = "PQR")
public class Pqr
{
    @DatabaseField(columnName = "ID", canBeNull = false)
    private String id;

    @DatabaseField(columnName = "ZZZ")
    private Zzz zzz;

    ... 
}

@DatabaseTable(tableName = "ZZZ")
public class Zzz
{
    @DatabaseField(columnName = "ID", canBeNull = false)
    private String id;

    @DatabaseField(columnName = "NAME")
    private String name;

    ... 
}

pqr and zzz are embedded objects.

Unfortunately as of September 2019 the answer is no, it doesn't. You will have to use foreign objects if you want to associate multiple classes.
