Member Function Documentation

GlueClient::GlueClient(const QtAws::Core::AwsRegion::Region region = QtAws::Core::AwsRegion::InvalidRegion, QtAws::Core::AwsAbstractCredentials *credentials = NULL, QNetworkAccessManager * const manager = NULL, QObject * const parent = 0)

Constructs a GlueClient object.

The new client object will region, credentials, and manager for network operations.

The new object will be owned by parent, if set.

GlueClient::GlueClient(const QUrl &endpoint, QtAws::Core::AwsAbstractCredentials *credentials = NULL, QNetworkAccessManager * const manager = NULL, QObject * const parent = 0)

This function overloads GlueClient().

This overload allows the caller to specify the specific endpoint to send requests to. Typically, it is easier to use the alternative constructor, which allows the caller to specify an AWS region instead, in which case this client will determine the correct endpoint for the given region automatically (via AwsEndpoint::getEndpoint).

See also QtAws::Core::AwsEndpoint::getEndpoint.
