public boolean isSame(Object x,
                      Object y)
               throws HibernateException

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) taking a shortcut for entity references.

For most types this should equate to an equals check on the values. For associations the implication is a bit different. For most types it is conceivable to simply delegate to Type.isEqual(java.lang.Object, java.lang.Object)

                throws HibernateException

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

参数:

x - The first value

y - The second value

返回:

True if there are considered equal (see discussion above).

                throws HibernateException

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).

从接口复制的说明: CompositeType

Is the given method a member of this component's class?

指定者:

isMethodOf 在接口中 CompositeType

参数:

method - The method to check

返回:

True if the method is a member; false otherwise.

getHashCode

public int getHashCode(Object x)

指定者:

getHashCode 在接口中 Type

覆盖:

getHashCode 在类中 AbstractType

参数:

x - The value for which to retrieve a hash code

返回:

The hash code

getHashCode

public int getHashCode(Object x,
                       SessionFactoryImplementor factory)

参数:

x - The value for which to retrieve a hash code

factory - The session factory

返回:

                       Object y,

                throws HibernateException

从接口复制的说明: Type

                          SharedSessionContractImplementor session)
                   throws HibernateException

从接口复制的说明: Type

Has the value been modified compared to the current database state? The difference between this and the Type.isDirty(java.lang.Object, java.lang.Object, org.hibernate.engine.spi.SharedSessionContractImplementor) methods is that here we need to account for "partially" built values. This is really only an issue with association types. For most type implementations it is enough to simply delegate to Type.isDirty(java.lang.Object, java.lang.Object, org.hibernate.engine.spi.SharedSessionContractImplementor) here/

指定者:

isModified 在接口中 Type

覆盖:

isModified 在类中 AbstractType

                      ForeignKeyDirection foreignKeyDirection)
               throws HibernateException

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

覆盖:

replace 在类中 AbstractType

参数:

original - the value from the detached entity being merged

target - the value in the managed entity

session - The originating session

owner - The owner of the value

copyCache - The cache of already copied/replaced values

foreignKeyDirection - For associations, which direction does the foreign key point?

返回:

the value to be merged

抛出:

HibernateException - An error from Hibernate
