SignatureStorage

All Implemented Interfaces:
```
public interface SignatureStorage

                    
```
Handles storing signatures. A signature is usually an ink signature (hand-written signature) that can be added to a PDF as an InkAnnotation. Additionally, a signature can be associated with a Signer for digitally signing a PDF.
Implement this class when creating your own signature storage, which you can then pass to the com.pspdfkit.ui.signatures.SignatureOptions.Builder. Additionally, you can use our default DatabaseSignatureStorage with your own database name.
To set a default signature storage that will be used when the ElectronicSignatureFragment is invoked by the framework, use setSignatureStorage.
