All Superinterfaces:

SignableRequest<T>

All Known Implementing Classes:

DefaultRequest

public interface Request<T>
extends SignableRequest<T>

Represents a request being sent to an Amazon Web Service, including the parameters being sent as part of the request, the endpoint to which the request should be sent, etc.

This class is only intended for use inside the AWS client libraries and request handlers. Users of the AWS SDK for Java should not implement this interface.

Method Detail

setHeaders

void setHeaders(Map<String,String> headers)

Sets all headers, clearing any existing ones.

setResourcePath

void setResourcePath(String path)

Sets the path to the resource being requested.

Parameters:

path - The path to the resource being requested.

withParameter

Request<T> withParameter(String name,
                       String value)

Adds the specified request parameter to this request, and returns the updated request object.

Parameters:

name - The name of the request parameter.

value - The value of the request parameter.

Returns:

The updated request object.

setParameters

void setParameters(Map<String,List<String>> parameters)

Sets all parameters, clearing any existing values. Note that List values within the parameters Map must use an implementation that supports null values.

setEndpoint

void setEndpoint(URI endpoint)

Sets the service endpoint (ex: "https://ec2.amazonaws.com") to which this request should be sent.

Parameters:

endpoint - The service endpoint to which this request should be sent.

setHttpMethod

void setHttpMethod(HttpMethodName httpMethod)

Sets the HTTP method (GET, POST, etc) to use when sending this request.

Parameters:

httpMethod - The HTTP method to use when sending this request.

getServiceName

String getServiceName()

Returns:

The name of the Amazon service this request is for. This is used as the service name set in request metrics and service exceptions. This is NOT the same as the service name returned by AmazonWebServiceClient.getServiceName() which is used for signing purpose.

See Also:

AmazonServiceException#getServiceName()}, AWSRequestMetrics.Field#ServiceName}

getOriginalRequest

AmazonWebServiceRequest getOriginalRequest()

Returns the original, user facing request object which this internal request object is representing.

setTimeOffset

void setTimeOffset(int timeOffset)

Sets the optional value for time offset for this request. This will be used by the signer to adjust for potential clock skew. Value is in seconds, positive values imply the current clock is "fast", negative values imply clock is slow.

Parameters:

timeOffset - The optional value for time offset (in seconds) for this request.

withTimeOffset

Request<T> withTimeOffset(int timeOffset)

Sets the optional value for time offset for this request. This will be used by the signer to adjust for potential clock skew. Value is in seconds, positive values imply the current clock is "fast", negative values imply clock is slow.

Returns:

The updated request object.

getAWSRequestMetrics

AWSRequestMetrics getAWSRequestMetrics()

Returns the request metrics.

setAWSRequestMetrics

void setAWSRequestMetrics(AWSRequestMetrics metrics)

Bind the request metrics to the request. Note metrics can be captured before the request is created.

Throws:

IllegalStateException - if the binding has already occurred

addHandlerContext

<X> void addHandlerContext(HandlerContextKey<X> key,
                         X value)

Adds a context to the request object that is visible to all RequestHandler2 . Note that, context added here will available only for the scope of the request execution and will not be marshalled over the wire.

Parameters:

key - the key for the property being set in the request.

value - the value for the property being set in the request.

getHandlerContext

<X> X getHandlerContext(HandlerContextKey<X> key)

Return the context for the given key if present; else return null.

Parameters:

key - the key for the context

Returns:

the context if present else null.
