visit_object()

static std::pair< bool, AbcObjectReader * > visit_object ( const IObject & object, AbcObjectReader::ptr_vector & readers, ImportSettings & settings, AbcObjectReader::ptr_vector & r_assign_as_parent )

static

Generates an AbcObjectReader for this Alembic object and its children.

Parameters

object	The Alembic IObject to visit.
readers	The created AbcObjectReader * will be appended to this vector.
settings	Import settings, not used directly but passed to the AbcObjectReader subclass constructors.
r_assign_as_parent	Return parameter, contains a list of reader pointers, whose parent pointer should still be set. This is filled when this call to visit_object() didn't create a reader that should be the parent.

Returns

A pair of boolean and reader pointer. The boolean indicates whether this IObject claims its parent as part of the same object (for example an IPolyMesh object would claim its parent, as the mesh is interpreted as the object's data, and the parent IXform as its Blender object). The pointer is the AbcObjectReader that represents the IObject parameter.

NOTE: this function is similar to gather_object_paths above, need to keep them in sync.
