7.1.1.1 The Library Object Construct Method

The method is presented two library object generation contexts: one generic and one class specific.

The generic one is described by a pair of bit flags set and a collection of library generation properties.

See struct x1f4_lxwide_type.

See Library Construct Generation Flags.

The class specific one will pertain the particular class of the library object being constructed. It is also introduced as a bit flags set and a attributes collection pair. For the libaime list library class, the two are a list library generation flags set and a struct x1f4_lxlist_type record.

See struct x1f4_lxlist_type.

See List Library Generation Flags.

The libaime library constructors comforming the uniform interface combine the two generation contexts, giving preference to the class specific context. Specifically:

• The class specific attributes that are not available in the generic context are taken from the class specific context. If the class defines mandatory attributes (like the output library class, that requires the actual methods) the class specific context must be available, otherwise it can be substituted by NULL.
• Optional attributes (those whose presence is indicated by the bit flags set) are taken from the class specific context, if present, from the generic context otherwise.
• The mandatory, non class specific attributes are taken from the generic context.
