IObjectGenerator_DG Interface

Create(string, object)
Create(string, IDictionary_DG)

The returned object is an interface. Its name is the type string. For an examle, a call to Create("IArray_DG", ..) returns IArray_DG interface.

Not all interfaces can be obtained this way. For an example, IBRepShape_DG is an abstract base interface. The object, which implements it, must be constructed as BRepSolid_DG, etc. concrete type.

The table below may be out of date after updates, so it is recomended to try name of the required interface

*) By default (Create method) IGeometry_DG is constructed as BRep type. To construct other types of geometry use Create() method with params containing string item named "Type" and value one of geometry types: "IBRep", "Mesh", etc. See IEntity_DG.SetGeometryType(). See an example below.

IUnk Create(string type)

See the comments above

There is a convenient extension for this method, which also includes a cast to the specific target type. Example:

void f(IObjectGenerator_DG gen)
    IFrame_DG frame = gen.Create<IFrame_DG>();

IUnk Create(string type, IUnk iParam)

iParam - a parameter specific for the requested type.

Type Expected iParam type
"IBRepEdge_DG" ICurve_DG
"IBRepWire_DG" ICurve_DG
"IBRepFace_DG" IBRepWire_DG or IUVSurface_DG

See the comments above for the other parameters


void f(IObjectGenerator_DG gen, IUnk iParam)
    IBRepEdge_DG edge = gen.Create("IBRepEdge_DG", iParam) as IBRepEdge_DG;
    IBRepEdge_DG edge2 = gen.Create<IBRepEdge_DG>(iParam);

IUnk Create(string type, IDictionary_DG params)

The method allows specifying additional parameters for the construction. Use call similar to:
    Dictionary_DG params = iObjectGenerator_DG.Create<IDictionary_DG>();
to create the dictionary.

The first imeplemented case is: type="IGeometry_DG" and params contains "Type" string with value one of geometry types: "BRep", "Mesh", etc. See IEntity_DG.SetGeometryType().


void f(IObjectGenerator_DG gen, IDictionary_DG params)
    params.SetString("Type", "Mesh");
    IGeometry_DG geom = gen.Create("IGeometry_DG", params) as IGeometry_DG;
    IGeometry_DG geom2 = gen.Create<IGeometry_DG>(params);
