Constructor Detail

Types.Identifiable

public Types.Identifiable(ClassMetaData meta,
                          MetamodelImpl model)

Method Detail

hasVersionAttribute

public boolean hasVersionAttribute()

Whether or not the identifiable type has a version attribute.

Specified by:

hasVersionAttribute in interface IdentifiableType<X>

Returns:

boolean indicating whether or not the identifiable type has a version attribute

getSupertype

public IdentifiableType<? super X> getSupertype()

Return the identifiable type that corresponds to the most specific mapped superclass or entity extended by the entity or mapped superclass.

Specified by:

getSupertype in interface IdentifiableType<X>

Returns:

super type of identifiable type or null if no such super type

hasIdAttribute

public boolean hasIdAttribute()

hasSingleIdAttribute

public boolean hasSingleIdAttribute()

Whether or not the identifiable type uses an attribute to represents its persistent identity. Returns true for a simple or embedded identifier. Returns false for an classes that use separate identifier class for its persistent identity.

Specified by:

hasSingleIdAttribute in interface IdentifiableType<X>

Returns:

boolean indicating whether or not the identifiable type represents its persistent identity via a single identifier attribute.

getIdType

public Type<?> getIdType()

Return the type that represents the type of the id.

Specified by:

getIdType in interface IdentifiableType<X>

Returns:

type of identifier
