Method Detail

getCredentials

public AWSCredentials getCredentials()

Description copied from interface: AWSCredentialsProvider

Returns AWSCredentials which the caller can use to authorize an AWS request. Each implementation of AWSCredentialsProvider can chose its own strategy for loading credentials. For example, an implementation might load credentials from an existing key management system, or load new credentials when credentials are rotated.

Specified by:

getCredentials in interface AWSCredentialsProvider

Returns:

AWSCredentials which the caller can use to authorize an AWS request.

refresh

public void refresh()

Description copied from interface: AWSCredentialsProvider

Forces this credentials provider to refresh its credentials. For many implementations of credentials provider, this method may simply be a no-op, such as any credentials provider implementation that vends static/non-changing credentials. For other implementations that vend different credentials through out their lifetime, this method should force the credentials provider to refresh its credentials.
