CustomTransactionSigner (bitcoinj-core 0.16.2 API)

java.lang.Object
- org.bitcoinj.signers.CustomTransactionSigner

All Implemented Interfaces:

TransactionSigner
```
public abstract class CustomTransactionSigner
extends java.lang.Object
implements TransactionSigner
```
This signer may be used as a template for creating custom multisig transaction signers.

Concrete implementations have to implement getSignature(Sha256Hash, List) method returning a signature and a public key of the keypair used to created that signature. It's up to custom implementation where to locate signatures: it may be a network connection, some local API or something else.
