public class AWSCredentialsProviderChain
extends java.lang.Object
implements AWSCredentialsProvider

AWSCredentialsProvider implementation that chains together multiple credentials providers. When a caller requests credentials from this provider, it calls all the providers in the chain, in the original order specified, until one can provide credentials, and then returns those credentials. If all of the credential providers in the chain have been called, and none of them can provide credentials, then this class will throw an exception indicated that no credentials are available.

メソッドの詳細

getCredentials

public AWSCredentials getCredentials()

インタフェースからコピーされた説明: 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.

戻り値:

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

refresh

public void refresh()

インタフェースからコピーされた説明: 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.
