JsonRpcContextMethod<S, T> class abstract

JSON RPC Context Method Decoder

An interface for JsonRpcMethods that return a response-context.

The valueDecoder defines how the value property of a successful JSON RPC response-context is mapped from S to T.

Example

class GetBalance extends JsonRpcContextMethod<int, int> {
  GetBalance(this.pubkey): super('getBalance');
  final String pubkey; // base-58 address.
  @override int valueDecoder(final int value) => value;
  @override Object? params([final Commitment? commitment]) => [pubkey];
}

final client = JsonRpcHttpClient(Cluster.devnet.uri);
final method = GetBalance('83astBRguLMdt2h5U1Tpdq5tjFoJ6noeGwaY3mDLVcri');
final response = await client.send(method.request(), method.response);
print(jsonEncode(response)); // {"jsonrpc":"2.0","result":{"context":{"slot":1},"value":0},"id":1}

Methods

decoder(Map<String, dynamic> value) → JsonRpcResponseContext<T>
Decodes the result property of a successful JSON RPC response.
override
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
params([Commitment? commitment]) → Object?
Returns the JSON RPC request's params property value.
inherited
request([Commitment? commitment]) → JsonRpcRequest
Creates a JsonRpcRequest to invoke method with params. The commitment level is provided as a default value to all methods that query bank state.
inherited
response(Map<String, dynamic> json) → JsonRpcResponse<JsonRpcResponseContext<T>>
Parses the json RPC response and returns the result.
inherited
toString() → String
A string representation of this object.
inherited
valueDecoder(S value) → T
Decodes the value property of a successful JSON RPC response-context.

Operators

operator ==(Object other) → bool
The equality operator.
