        已过时。
        Use EntityType(org.hibernate.type.TypeFactory.TypeScope, String, boolean, String, boolean, boolean) instead.
        Constructs the requested entity type mapping.
        参数:
        scope - The type scope
        entityName - The name of the associated entity.
        uniqueKeyPropertyName - The property-ref name, or null if we reference the PK of the associated entity.
        eager - Is eager fetching enabled.
        unwrapProxy - Is unwrapping of proxies allowed for this association; unwrapping says to return the "implementation target" of lazy proxies; typically only possible with lazy="no-proxy".

        覆盖:
        isEntityType 在类中 AbstractType
        返回:
        True.

      • isMutable

        public boolean isMutable()
        从接口复制的说明: Type
        Are objects of this type mutable. (With respect to the referencing object ... entities and collections are considered immutable because they manage their own internal state.)
        指定者:
        isMutable 在接口中 Type
        返回:
        boolean

      • toString

        public String toString()
        Generates a string representation of this type.
        覆盖:
        toString 在类中 Object
        返回:
        string rep

      • getName

        public String getName()
        For entity types, the name correlates to the associated entity name.
        指定者:
        getName 在接口中 Type
        返回:
        String the Hibernate type name

      • isReferenceToPrimaryKey

        public boolean isReferenceToPrimaryKey()
        Does this association foreign key reference the primary key of the other table? Otherwise, it references a property-ref.
        返回:
        True if this association reference the PK of the associated entity.

      • getRHSUniqueKeyPropertyName

        public String getRHSUniqueKeyPropertyName()
        从接口复制的说明: AssociationType
        The name of a unique property of the associated entity that provides the join key (null if the identifier of an entity, or key of a collection)
        指定者:

        返回:
        The associated entity name.

      • getReturnedClass

        public final Class getReturnedClass()
        This returns the wrong class for an entity with a proxy, or for a named entity. Theoretically it should return the proxy class, but it doesn't.

        The problem here is that we do not necessarily have a ref to the associated entity persister (nor to the session factory, to look it up) which is really needed to "do the right thing" here...

        指定者:
        getReturnedClass 在接口中 Type
        返回:
        The entity class.

        参数:
        st - The JDBC prepared statement to which to bind

        从接口复制的说明: Type
        During merge, replace the existing (target) value in the entity we are merging to with a new (original) value from the detached entity we are merging. For immutable objects, or null values, it is safe to simply return the first parameter. For mutable objects, it is safe to return a copy of the first parameter. For objects with component values, it might make sense to recursively replace component values.
        指定者:
        replace 在接口中 Type
        参数:
        original - the value from the detached entity being merged

        从接口复制的说明: Type
        Get a hash code, consistent with persistence "equality". Again for most types the normal usage is to delegate to the value's hashCode.

        getHashCode 在接口中 Type
        覆盖:
        getHashCode 在类中 AbstractType

        从接口复制的说明: Type
        Compare two instances of the class mapped by this type for persistence "equality" (equality of persistent state).

        This should always equate to some form of comparison of the value's internal state. As an example, for something like a date the comparison should be based on its internal "time" state based on the specific portion it is meant to represent (timestamp, date, time).

        指定者:
        isEqual 在接口中 Type
        覆盖:
        isEqual 在类中 AbstractType

      • getSemiResolvedType

        public Type getSemiResolvedType​(SessionFactoryImplementor factory)
        从接口复制的说明: Type
        As part of 2-phase loading, when we perform resolving what is the resolved type for this type? Generally speaking the type and its semi-resolved type will be the same. The main deviation from this is in the case of an entity where the type would be the entity type and semi-resolved type would be its identifier type
        指定者:
        getSemiResolvedType 在接口中 Type
        覆盖:
        getSemiResolvedType 在类中 AbstractType

        factory - The session factory
        返回:
        The semi-resolved type
