Instance methods

configure

Configures a component by passing its configuration parameters.

configure(config: ConfigParams)

  • config: ConfigParams - configuration parameters to be set.

resolve

Resolves a connection and credential parameters and generates a single AWSConnectionParams value.

resolve(correlation_id: Optional[str]): AwsConnectionParams

  • correlation_id: Optional[str] - (optional) transaction id used to trace execution through the call chain.
  • returns: AwsConnectionParams - receives an AWSConnectionParams value or error.

set_references

Sets references to dependent components.

set_references(references: IReferences)

  • references: IReferences - references to locate the component’s dependencies.

Examples

config = ConfigParams.from_tuples(
    "connection.region", "us-east1",
    "connection.service", "s3",
    "connection.bucket", "mybucket",
    "credential.access_id", "XXXXXXXXXX",
    "credential.access_key", "XXXXXXXXXX"
)

connection_resolver = AwsConnectionResolver()
connection_resolver.configure(config)
connection_resolver.set_references(references)
connection_params = connection_resolver.resolve("123")
