Signer	getSignerByURI(URI uri) Returns the signer for the given uri.
void	markRetryCapacityConsumed() Marks that a retry during this request lifecycle has consumed retry capacity.
boolean	retryCapacityConsumed() Returns whether retry capacity was consumed during this request lifecycle.
void	setAuthErrorRetryStrategy(com.amazonaws.retry.internal.AuthErrorRetryStrategy authErrorRetryStrategy) Sets the optional auth error retry strategy for this request execution.

Constructor Detail

ExecutionContext

public ExecutionContext(boolean isMetricEnabled)

For testing purposes.

ExecutionContext

public ExecutionContext()

For testing purposes.

ExecutionContext

public ExecutionContext(List<RequestHandler2> requestHandler2s,
                        boolean isMetricEnabled,
                        AmazonWebServiceClient awsClient)

Method Detail

getContextUserAgent

public String getContextUserAgent()

setContextUserAgent

public void setContextUserAgent(String contextUserAgent)

getRequestHandler2s

public List<RequestHandler2> getRequestHandler2s()

getAwsRequestMetrics

public AWSRequestMetrics getAwsRequestMetrics()

getAwsClient

protected AmazonWebServiceClient getAwsClient()

setSigner

public void setSigner(Signer signer)

There is in general no need to set the signer in the execution context, since the signer for each request may differ depending on the URI of the request. The exception is S3 where the signer is currently determined only when the S3 client is constructed. Hence the need for this method. We may consider supporting a per request level signer determination for S3 later on.

retryCapacityConsumed

public boolean retryCapacityConsumed()

Returns whether retry capacity was consumed during this request lifecycle. This can be inspected to determine whether capacity should be released if a retry succeeds.

Returns:

true if retry capacity was consumed

markRetryCapacityConsumed

public void markRetryCapacityConsumed()

Marks that a retry during this request lifecycle has consumed retry capacity. This is inspected when determining if capacity should be released if a retry succeeds.

getSignerByURI

public Signer getSignerByURI(URI uri)

Returns the signer for the given uri. Note S3 in particular overrides this method.

getCredentials

@Deprecated
public AWSCredentials getCredentials()

Deprecated. in favor of getCredentialsProvider()

Returns the credentials used to sign the associated request.

This method is deprecated as the provider needs to be used every time we fetch the credentials.

Returns:

The credentials used to sign the associated request.

setCredentials

@Deprecated
public void setCredentials(AWSCredentials credentials)

Deprecated. in favor of setCredentialsProvider(AWSCredentialsProvider)

Sets the credentials used to sign the associated request. If no credentials are specified as part of a request's ExecutionContext, then the runtime layer will not attempt to sign (or resign on retries) requests.

This method is deprecated as the provider needs to be used every time we fetch the credentials.

Parameters:

credentials - The optional credentials used to sign the associated request.

setCredentialsProvider

public void setCredentialsProvider(AWSCredentialsProvider credentialsProvider)

Sets the credentials provider used for fetching the credentials. The credentials fetched is used for signing the request. If there is no credential provider, then the runtime will not attempt to sign (or resign on retries) requests.

Parameters:

credentialsProvider - the credentials provider to fetch AWSCredentials

getCredentialsProvider

public AWSCredentialsProvider getCredentialsProvider()

Returns the credentials provider used for fetching the credentials. The credentials fetched is used for signing the request. If there is no credential provider, then the runtime will not attempt to sign (or resign on retries) requests.

Returns:

the credentials provider to fetch AWSCredentials

getAuthErrorRetryStrategy

public com.amazonaws.retry.internal.AuthErrorRetryStrategy getAuthErrorRetryStrategy()

Returns the retry strategy for auth errors. This is currently only used by the S3 client for auto-resolving sigv4-required regions.

Note that this will be checked BEFORE the HTTP client consults the user-specified RetryPolicy. i.e. if the configured AuthErrorRetryStrategy says the request should be retried, the retry will be performed internally and the effect is transparent to the user's RetryPolicy.

setAuthErrorRetryStrategy

public void setAuthErrorRetryStrategy(com.amazonaws.retry.internal.AuthErrorRetryStrategy authErrorRetryStrategy)

Sets the optional auth error retry strategy for this request execution.

getClientExecutionTrackerTask

public ClientExecutionAbortTrackerTask getClientExecutionTrackerTask()

setClientExecutionTrackerTask

public void setClientExecutionTrackerTask(ClientExecutionAbortTrackerTask clientExecutionTrackerTask)
