修饰符和类型	方法	说明
boolean	doCascade(CascadingAction action)	For this style, should the given action be cascaded?
boolean	hasOrphanDelete()	Do we need to delete orphaned collection elements?
boolean	reallyDoCascade(CascadingAction action)	Probably more aptly named something like doCascadeToCollectionElements(); it is however used from both the collection and to-one logic branches...

方法详细资料

doCascade

boolean doCascade(CascadingAction action)

For this style, should the given action be cascaded?

参数:

action - The action to be checked for cascade-ability.

返回:

True if the action should be cascaded under this style; false otherwise.

reallyDoCascade

boolean reallyDoCascade(CascadingAction action)

Probably more aptly named something like doCascadeToCollectionElements(); it is however used from both the collection and to-one logic branches...

For this style, should the given action really be cascaded? The default implementation is simply to return doCascade(org.hibernate.engine.spi.CascadingAction); for certain styles (currently only delete-orphan), however, we need to be able to control this separately.

参数:

action - The action to be checked for cascade-ability.

返回:

True if the action should be really cascaded under this style; false otherwise.

hasOrphanDelete

boolean hasOrphanDelete()

Do we need to delete orphaned collection elements?

返回:

True if this style need to account for orphan delete operations; false otherwise.
