Syntax

resource-id=LOADRES(resource-name);

resource-id

resource-name

is the RESOURCE catalog entry to load. If resource-name is a one- or two-level name, the current search path is used to find the RESOURCE entry.

Type: Character

Details

LOADRES loads a list of classes from a RESOURCE entry. This list is called a resource list. RESOURCE entries are used primarily by FRAME entries, although you can create RESOURCE entries for component classes as well. This function is useful for loading several classes or even entire class hierarchies at one time instead of having to load several CLASS entries.

If a class contained in the resource list has already been loaded, the existing class replaces the class in the resource list (although the RESOURCE entry is not modified). This prevents duplicate class lists for the same class name.

Example

Load a resource list that is stored in APPQR.HIER1.GROUPS.RESOURCE, then load several classes contained in the RESOURCE entry. After the LOADRES call, the LOADCLASS calls do not have to read the classes from the catalog.

groups = loadres('appqr.hier1.groups.resource');
   c1=loadclass('appqr.hier1.c1.class');
   c2=loadclass('appqr.hier1.c2.class');
   c3=loadclass('appqr.hier1.c3.class');
