  • Method Summary

    Modifier and Type
    Method
    Description
    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...

  • Method Details

    • doCascade

      boolean doCascade(CascadingAction<?> action)
      For this style, should the given action be cascaded?
      Parameters:
      action - The action to be checked for cascade-ability.
      Returns:
      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.

      Parameters:
      action - The action to be checked for cascade-ability.
      Returns:
      True if the action should be really cascaded under this style; false otherwise.

    • hasOrphanDelete

      boolean hasOrphanDelete()
      Do we need to delete orphaned collection elements?
      Returns:
      True if this style need to account for orphan delete operations; false otherwise.
