Method Detail

hasPhysicalColumn

public boolean hasPhysicalColumn()

Description copied from interface: EntityDiscriminatorMapping

Is the discriminator defined by a physical column?

generateFetch

public BasicFetch<?> generateFetch(FetchParent fetchParent,
                                   NavigablePath fetchablePath,
                                   FetchTiming fetchTiming,
                                   boolean selected,
                                   String resultVariable,
                                   DomainResultCreationState creationState)

Description copied from interface: Fetchable

Generates a Fetch of this fetchable

Specified by:

generateFetch in interface EntityDiscriminatorMapping

Specified by:

generateFetch in interface Fetchable

Overrides:

generateFetch in class AbstractDiscriminatorMapping

Parameters:

fetchParent - The parent of the Fetch we are generating

fetchablePath - The overall path within the graph

fetchTiming - The requested fetch timing

resolveSqlExpression

public Expression resolveSqlExpression(NavigablePath navigablePath,
                                       JdbcMapping jdbcMappingToUse,
