Functions

func AfterCreateFromFront 

func AfterCreateFromFront[Type Gongstruct](stage *StageStruct, instance *Type)

AfterCreateFromFront is called after a create from front

func AfterDeleteFromFront 

func AfterDeleteFromFront[Type Gongstruct](stage *StageStruct, staged, front *Type)

AfterDeleteFromFront is called after a delete from front

func AfterReadFromFront

func EvictInOtherSlices 

func EvictInOtherSlices[OwningType PointerToGongstruct, FieldType PointerToGongstruct](
	stage *StageStruct,
	owningInstance OwningType,
	sliceField []FieldType,
	fieldName string)

EvictInOtherSlices allows for adherance between the gong association model and go.

Says you have a Astruct struct with a slice field "anarrayofb []*Bstruct"

go allows many Astruct instance to have the anarrayofb field that have the same pointers. go slices are MANY-MANY association.

With gong it is only ZERO-ONE-MANY associations, a Bstruct can be pointed only once by an Astruct instance through a given field. This follows the requirement that gong is suited for full stack programming and therefore the association is encoded as a reverse pointer (not as a joint table). In gong, a named struct is translated in a table and each table is a named struct.

EvictInOtherSlices removes the fields instances from other fields of other instance

Note : algo is in O(N)log(N) of nb of Astruct and Bstruct instances
