getQuerySpaces
public Serializable[] getQuerySpaces()
- Description copied from interface:
EntityPersister
- Returns an array of objects that identify spaces in which properties of
this entity are persisted, for instances of this class and its subclasses.
Much like
EntityPersister.getPropertySpaces(), except that here we include subclass
entity spaces.
- Specified by:
getQuerySpaces in interface EntityPersister- Overrides:
getQuerySpaces in class AbstractEntityPersister
getTableName
public String getTableName()
- Description copied from interface:
Joinable
- The table to join to.
getDiscriminatorType
public Type getDiscriminatorType()
- Description copied from interface:
Loadable
- Get the discriminator type
getDiscriminatorSQLValue
public String getDiscriminatorSQLValue()
- Description copied from interface:
Queryable
- Get the discriminator value for this particular concrete subclass,
as a string that may be embedded in a select statement

getPropertySpaces
public Serializable[] getPropertySpaces()
- Description copied from interface:

For most implementations, this returns the complete set of table names
to which instances of the mapped entity are persisted (not accounting
for superclass entity mappings).
- Returns:
- The property spaces.
