Examples with RegionAwareSigner com.amazonaws.auth.RegionAwareSigner used on opensource projects

Example 1 with RegionAwareSigner

use of com.amazonaws.auth.RegionAwareSigner in project aws-sdk-android by aws-amplify.

the class AmazonWebServiceClient method computeSignerByServiceRegion.

/**
 * Returns the signer for the given service name, region id, and the current
 * client configuration.
 * <p>
 * Note, however, the signer returned for S3 is incomplete at this stage as
 * the information on the S3 bucket and key is not yet known.
 *
 * @param regionId the region for sending AWS requests
 * @param signerRegionOverride the overriding signer region; or null if
 *            there is none.
 * @param isRegionIdAsSignerParam true if the "regionId" is used to
 *            configure the signer if applicable; false if this method is
 *            called for the purpose of purely setting the communication end
 *            point of this AWS client, and therefore the "regionId"
 *            parameter will not be used directly for configuring the
 *            signer.
