IFSelect_SelectAnyList Class Referenceabstract

A SelectAnyList kind Selection selects a List of an Entity, as
well as this Entity contains some. A List contains sub-entities
as one per Item, or several (for instance if an Entity binds
couples of sub-entities, each item is one of these couples).
Remark that only Entities are taken into account (neither
Reals, nor Strings, etc...)

To define the list on which to work, SelectAnyList has two
deferred methods : NbItems (which gives the length of the
list), FillResult (which fills an EntityIterator). They are
intended to get a List in an Entity of the required Type (and
consider that list is empty if Entity has not required Type)

In addition, remark that some types of Entity define more than
one list in each instance : a given sub-class of SelectAnyList
must be attached to one list

SelectAnyList keeps or rejects a sub-set of the list,
that is the Items of which rank in the list is in a given
range (for instance form 2nd to 6th, etc...)
Range is defined by two Integer values. In order to allow
external control of them, these values are not directly
defined as fields, but accessed through IntParams, that is,
referenced as Transient (Handle) objects

Warning : the Input can be any kind of Selection, BUT its
RootResult must have zero (empty) or one Entity maximum

Detailed Description

A SelectAnyList kind Selection selects a List of an Entity, as
well as this Entity contains some. A List contains sub-entities
as one per Item, or several (for instance if an Entity binds
couples of sub-entities, each item is one of these couples).
Remark that only Entities are taken into account (neither
Reals, nor Strings, etc...)

To define the list on which to work, SelectAnyList has two
deferred methods : NbItems (which gives the length of the
list), FillResult (which fills an EntityIterator). They are
intended to get a List in an Entity of the required Type (and
consider that list is empty if Entity has not required Type)

In addition, remark that some types of Entity define more than
one list in each instance : a given sub-class of SelectAnyList
must be attached to one list

SelectAnyList keeps or rejects a sub-set of the list,
that is the Items of which rank in the list is in a given
range (for instance form 2nd to 6th, etc...)
Range is defined by two Integer values. In order to allow
external control of them, these values are not directly
defined as fields, but accessed through IntParams, that is,
referenced as Transient (Handle) objects

Warning : the Input can be any kind of Selection, BUT its
RootResult must have zero (empty) or one Entity maximum
