+## Create an Abstract Model

+
+#### constructor()
+
+```typescript
+const abstractModel = await createAbstractModel({ ... });
+```
+
+**Returns**:
+
+`Promise`
+
+**Description**:
+
+The purpose of this class, is to create a model to be kept in memory during the application runtime. It contains a processed version of the passed `model` (already read and splitted) and, if passed, a processed version of the `certificates`, along with the chosen overrides.
+Since `certificates` and `overrides` might differ time to time or not available at the moment of the abstract model creation, an additional attribute has been added to [`createPass`](#pass_class_constructor) function. It is an object that accepts `overrides` and raw `certificates`
+
+**Arguments**:
+
+It accepts only one argument: an `options` object, which is identical to the first parameter of [`createPass`](#pass_class_constructor). You can refer to that method to compile it correctly.
+
+
+
+

+
+#### [Getter] .bundle()
+
+```typescript

+#### [Getter] .certificates()
+
+```typescript
+abstractModel.certificates
+```
+
+**Returns**:
+
+An object containing processed certificates.
+

+
+
+#### [Getter] .overrides()
+
+```typescript
+abstractModel.overrides
+```
+
+**Returns**:
+
+An object containing passed overrides.
