Methods

getBytes

getBytes(): Uint8Array
Get the serialized bytes of the signable object. Serialized bytes can be used to recreate the object using methods on Gateway.

Returns Uint8Array
Inherited from Signable.getBytes
- Defined in src/signable.d.ts:15

getDigest

getDigest(): Uint8Array
Get the digest of the signable object. This is used to generate a digital signature.

Returns Uint8Array
Inherited from Signable.getDigest
- Defined in src/signable.d.ts:20

getEvents

getEvents(options?): Promise<CloseableAsyncIterable<ChaincodeEvent>>
Get chaincode events emitted by transaction functions of a specific chaincode.
Parameters
- Optionaloptions: CallOptions
  gRPC CallOptions.
Returns Promise<CloseableAsyncIterable<ChaincodeEvent>>
Chaincode events. The iterator should be closed after use to complete the eventing session.
Throws
GatewayError Thrown by the iterator if the gRPC service invocation fails.
Example
```
const events = await request.getEvents();
try {
    for await (const event of events) {
        // Process event
    }
} finally {
    events.close();
}
```
