Memory Methods on Surface

 

   (SURFACE * ) GRAPE(Surface, "new-instance")(name)

CLASS * Surface
char * name

Create an instance of class Surface with name name. Additional to the superclass method the asso variable is initialized by calling "get-asso", to allocate memory for the geometries use "list-alloc".

   GRAPE(surface, "free")()

SURFACE * surface

Free the memory of a Surface instance by sending "list-free" to it and "free" to the superclass. See 5.4.4.1 for details on "delete"/"free".

     

SURFACE * surface
int points, bnds

"list-alloc" initializes all Surface instance variables by calling the superclass "list-alloc" method -- therefore num_of_frames has to be set before "list-alloc" is called -- and creating reflect and the Chains for the geometries and conj_inter.

For the objects of the geometries geometry, domain, gauss and conjugate sequences of num_of_frames frames with Geom2d instances as objects are created using TimeStep "alloc" and "create-objects". For each Geom2d instance memory for points points, 2* points elements and bnds boundary curves is allocated.

"list-free" frees all memory of the surface instance by deleting all geometry instance variables and calling "list-free" on the superclass Time_Object.

     

SURFACE * surface, * copy

Create a copy of surface and return it. From the geometrical point of view there is only one real difference between these two methods: "softcopy" uses a given copy to store the copy, if copy is NULL it allocates a new instance (as "hardcopy" does). From the physical point of view the copies created by "hardcopy" and "softcopy" differ since they use "hardcopy" resp.\ "softcopy" to copy the superclass data and the geometries.
