Method Detail

matchesRoleName

static boolean matchesRoleName(String name)

getPartName

default String getPartName()

Specified by:

getPartName in interface ModelPart

getFetchableName

default String getFetchableName()

Description copied from interface: Fetchable

The name of the fetchable

Specified by:

getFetchableName in interface Fetchable

getConcreteEntityNameForDiscriminatorValue

String getConcreteEntityNameForDiscriminatorValue(Object value)

isPhysical

boolean isPhysical()

resolveSqlExpression

Expression resolveSqlExpression(NavigablePath navigablePath,
                                JdbcMapping jdbcMappingToUse,
                                TableGroup tableGroup,
                                SqlAstCreationState creationState)

Create the appropriate SQL expression for this discriminator

Parameters:

jdbcMappingToUse - The JDBC mapping to use. This allows opting between the "domain result type" (aka Class) and the "underlying type" (Integer, String, etc)

generateFetch

fetchablePath - The overall path within the graph

fetchTiming - The requested fetch timing

getMappedFetchOptions

default FetchOptions getMappedFetchOptions()

Description copied from interface: Fetchable

The configured fetch timing and style

Specified by:

getMappedFetchOptions in interface Fetchable

getStyle
