Function Documentation

Gj_View * Gj_view_new ( Gj_Ctx * ctx, char * name, Gj_Id * id, Gj_Id * type, Gj_Path * nativefunc )

Create a new view structure. Name may be 0. Id may be 0, in this case a new id is assigned. Nativefunc may be 0. Nativefunc will not be NOT DUPLICATED, the view will overtake the OWNERSHIP of the path. Returns: The pointer to the structure on success, 0 otherwise.

Gj_View * Gj_view_create ( Gj_Ctx * ctx, Gj_Stream * stream )

Create a view form a stream. Returns: The pointer to the view on success, 0 otherwise.

int Gj_view_delete ( Gj_Ctx * ctx, Gj_View * ptr )

Delete a view structure. Returns: 0 on success, -1 otherwise.

int Gj_view_write ( Gj_Ctx * ctx, Gj_View * view, Gj_Stream * stream )

Write a view to a stream. Returns: 0 on success, -1 otherwise.

void Gj_view_register ( Gj_Ctx * ctx, Gj_View * view )

Register a view. A locally unique id is assigned if no other set.

void Gj_view_finish ( Gj_Ctx * ctx, Gj_View * view )

Finish a view. The/a global unique id is assigned. The view cannot be changed anymore.

char * Gj_view_getName ( Gj_View * view )

Get the name of the view. Return value 0 means no name is set.

Gj_Id * Gj_view_getId ( Gj_Ctx * ctx, Gj_View * view )

Get the id of a view. The id is STILL OWNED by the view. Returns: The pointer to the id on success, 0 otherwise.

int Gj_view_addParameter ( Gj_Ctx * ctx, Gj_View * view, char * name, Gj_Id * type )

Add a parameter. Returns: 0 on success, -1 otherwise.

int Gj_view_getParameterNumber ( Gj_Ctx * ctx, Gj_View * view, char * name )

Get the number of a parameter given by its name. Returns: The number of the parameter on success, -1 otherwise.

int Gj_view_setDefinition ( Gj_Ctx * ctx, Gj_View * view, Gj_Object * def )

Set the definition of the view. This functions should be called AFTER all needed calls to Gj_view_addParameter() were made. The object is NOT duplicated. Returns: 0 on success, -1 otherwise.

Gj_Id * Gj_view_getType ( Gj_View * view )

Get the return type of the view. The returned id is STILL OWNED by the view.
