Method Detail

sign

public void sign(Request<?> request,
        AWSCredentials credentials)

Description copied from interface: Signer

Sign the given request with the given set of credentials. Modifies the passed-in request to apply the signature.

Specified by:

sign in interface Signer

Parameters:

request - The request to sign.

credentials - The credentials to sign the request with.

setServiceName

public void setServiceName(String serviceName)

Sets the service name that this signer should use when calculating request signatures. This can almost always be determined directly from the request's end point, so you shouldn't need this method, but it's provided for the edge case where the information is not in the endpoint.

Specified by:

setServiceName in interface ServiceAwareSigner

Parameters:

serviceName - The service name to use when calculating signatures in this signer.

setRegionName

public void setRegionName(String regionName)

Sets the region name that this signer should use when calculating request signatures. This can almost always be determined directly from the request's end point, so you shouldn't need this method, but it's provided for the edge case where the information is not in the endpoint.

Specified by:

setRegionName in interface RegionAwareSigner

Parameters:

regionName - The region name to use when calculating signatures in this signer.
