Text string Description:
The MapVert_ItemList is equivalent to the MapHorz_ItemList for vertical displays.
A MapVert_ItemList contains a list of Items to be drawn. This list is of fixed size
specified through the maximum number of Items. The type of each Item inside the
MapVert_ItemList can be modified at run-time, which makes the list dynamic. A set
of parameters is associated with each type of Item (refer to Section 3.3.22.2.1,
Item Structure).
One or several items can be modified through a SetParameter command with
BufferOfItems as Parameter_Ident. An Item should be modified in its entirety. For
instance, the X coordinate of a symbol can not be changed by itself.
Insert and delete operations are not allowed on the list. However, one specific type
of Item is NOT_USED. The Item with the NOT_USED type will be ignored, i.e., is
they will have no effect on the processing of following items.
Section 3.4.5.1 describes the standardized items and their functionality. Section
3.4.5.2 describes the A661_ParameterStructure to address the Items.
Restriction:
A MapVert_ItemList must be in a MapVert_Source container.
