NewKafkaConnectionResolver() *KafkaConnectionResolver
Fields
Methods
Compose
Composes Kafka connection options from connection and credential parameters.
(c [*KafkaConnectionResolver]) Compose(correlationId string, connections []*ConnectionParams, credential *CredentialParams) (*ConfigParams, error)
- correlationId: string - (optional) transaction id used to trace execution through the call chain.
- connections: []*ConnectionParams - connection parameters
- credential: *CredentialParams - credential parameters
- returns: (*ConfigParams, error) - resolved Kafka connection options.
Configure
Configures the component by passing its configuration parameters.
(c [*KafkaConnectionResolver]) Configure(ctx context.Context, config *ConfigParams)
- ctx: context.Context - operation context.
- config: ConfigParams - configuration parameters to be set.
Resolve
Resolves Kafka connection options from connection and credential parameters.
(c [*KafkaConnectionResolver]) Resolve(correlationId string) (*ConfigParams, error)
- correlationId: string - (optional) transaction id used to trace execution through the call chain.
- returns: (*ConfigParams, error) - resolved Kafka connection options.
SetReferences
Sets references to dependent components.
(c [*KafkaConnectionResolver]) SetReferences(ctx context.Context,references IReferences)
- ctx: context.Context - operation context.
- references: IReferences - references to locate the component’s dependencies.
