## Detailed Description

A product registered in the store

QInAppProduct encapsulates a product in the external store after it has been registered in `QInAppStore` and confirmed to exist. It has an identifier which matches the identifier of the product in the external store, it has a price which is retrieved from the external store, and it has a product type.

The product type can be either `Consumable` or `Unlockable`. The former type of products can be purchased any number of times as long as each transaction is finalized explicitly by the application. The latter type can only be purchased once.

## Member Type Documentation

### enum QInAppProduct::ProductType

This enum type is used to specify the product type when registering the product.

Constant | Value | Description
--- | --- | ---
`QInAppProduct::Consumable` | `0` | The product is consumable, meaning that once the transaction for a purchase of the product has been finalized, it can be purchased again.
`QInAppProduct::Unlockable` | `1` | The product is unlockable, meaning that it can only be purchased once per user. Purchases of unlockable products can be restored using the QInAppStore::restorePurchases().

### `[pure virtual]` void QInAppProduct::purchase()
