Declaration Manager
|
|
|
|
All "small text" data types, like materials, sound shaders, fx files,
|
|
entity defs, etc. are managed uniformly, allowing reloading, purging,
|
|
listing, printing, etc. All "large text" data types that never have more
|
|
than one declaration in a given file, like maps, models, AAS files, etc.
|
|
are not handled here.
|
|
|
|
A decl will never, ever go away once it is created. The manager is
|
|
garranteed to always return the same decl pointer for a decl type/name
|
|
combination. The index of a decl in the per type list also stays the
|
|
same throughout the lifetime of the engine. Although the pointer to
|
|
a decl always stays the same, one should never maintain pointers to
|
|
data inside decls. The data stored in a decl is not garranteed to stay
|
|
the same for more than one engine frame.
|
|
|
|
The decl indexes of explicitely defined decls are garrenteed to be
|
|
consistent based on the parsed decl files. However, the indexes of
|
|
implicit decls may be different based on the order in which levels
|
|
are loaded.
|
|
|
|
The decl namespaces are separate for each type. Comments for decls go
|
|
above the text definition to keep them associated with the proper decl.
|
|
|
|
During decl parsing, errors should never be issued, only warnings
|
|
followed by a call to MakeDefault().
