java.lang.Object
- jakarta.json.bind.spi.JsonbProvider

```
public abstract class JsonbProvider
extends java.lang.Object
```
Service provider for JSON Binding implementations. Provider implementors must implement all abstract methods. API clients can obtain instance of default provider by calling:
```
 
 JsonbProvider provider = JsonbProvider.provider();
 }
```
Specific provider instance lookup:
```
 
 JsonbProvider provider;
 try {
   JsonbProvider.provider("foo.bar.ProviderImpl");
 } catch (JsonbException e) {
   // provider not found or could not be instantiated
 }
```
where 'foo.bar.ProviderImpl' is a vendor implementation class extending JsonbProvider and identified to service loader as specified in ServiceLoader documentation.
All the methods in this class are allowed to be called by multiple concurrent threads.
