Method Detail

setEndpoint

void setEndpoint(java.lang.String endpoint)
          throws java.lang.IllegalArgumentException

Overrides the default endpoint for this client ("https://https://kinesisvideo.us-west-2.amazonaws.com"). Callers can use this method to control which AWS region they want to work with.

Callers can pass in just the endpoint (ex: "https://kinesisvideo.us-west-2.amazonaws.com") or a full URL, including the protocol (ex: "https://https://kinesisvideo.us-west-2.amazonaws.com"). If the protocol is not specified here, the default protocol from this client's ClientConfiguration will be used, which by default is HTTPS.

For more information on using AWS regions with the AWS SDK for Java, and a complete list of all available endpoints for all AWS services, see: http://developer.amazonwebservices.com/connect/entry.jspa?externalID= 3912

This method is not threadsafe. An endpoint should be configured when the client is created and before any service requests are made. Changing it afterwards creates inevitable race conditions for any service requests in transit or retrying.

Parameters:

endpoint - The endpoint (ex: "https://kinesisvideo.us-west-2.amazonaws.com") or a full URL, including the protocol (ex: "https://https://kinesisvideo.us-west-2.amazonaws.com") of the region specific AWS endpoint this client will communicate with.

Throws:

java.lang.IllegalArgumentException - If any problems are detected with the specified endpoint.

setRegion

void setRegion(Region region)
        throws java.lang.IllegalArgumentException

An alternative to setEndpoint(String), sets the regional endpoint for this client's service calls. Callers can use this method to control which AWS region they want to work with.

By default, all service endpoints in all regions use the https protocol. To use http instead, specify it in the ClientConfiguration supplied at construction.

This method is not threadsafe. A region should be configured when the client is created and before any service requests are made. Changing it afterwards creates inevitable race conditions for any service requests in transit or retrying.

Parameters:

region - The region this client will communicate with. See Region.getRegion(com.amazonaws.regions.Regions) for accessing a given region.

Throws:

java.lang.IllegalArgumentException - If the given region is null, or if this service isn't available in the given region. See Region.isServiceSupported(String)

                                AmazonServiceException

Creates a new Kinesis video stream.

When you create a new stream, Kinesis Video Streams assigns it a version number. When you change the stream's metadata, Kinesis Video Streams updates the version.

                                AmazonServiceException

Deletes a Kinesis video stream and the data contained in the stream.

This method marks the stream for deletion, and makes the data in the stream inaccessible immediately.

To ensure that you have the latest version of the stream before deleting it, you can specify the stream version. Kinesis Video Streams assigns a version to each stream. When you update a stream, Kinesis Video Streams assigns a new version number. To get the latest stream version, use the DescribeStream API.

Gets an endpoint for a specified stream for either reading or writing. Use this endpoint in your application to read from the specified stream (using the GetMedia or GetMediaForFragmentList operations) or write to it (using the PutMedia operation).

The returned endpoint does not have the API name appended. The client needs to add the API name to the returned endpoint.

In the request, specify the stream either by StreamName or StreamARN.

Provides an endpoint for the specified signaling channel to send and receive messages. This API uses the SingleMasterChannelEndpointConfiguration input parameter, which consists of the Protocols and Role properties.

Protocols is used to determine the communication mechanism. For example, specifying WSS as the protocol, results in this API producing a secure websocket endpoint, and specifying HTTPS as the protocol, results in this API generating an HTTPS endpoint.

Role determines the messaging permissions. A MASTER role results in this API generating an endpoint that a client can use to communicate with any of the viewers on the channel. A VIEWER role results in this API generating an endpoint that a client can use to communicate only with a MASTER.

AmazonServiceException - If an error response is returned by AWSKinesisVideoFrontend indicating either a problem with the data in the request, or a server side issue.

shutdown

void shutdown()

Shuts down this client object, releasing any resources that might be held open. This is an optional method, and callers are not expected to call it, but can if they want to explicitly release any open resources. Once a client has been shutdown, it should not be used to make any more requests.

getCachedResponseMetadata

ResponseMetadata getCachedResponseMetadata(AmazonWebServiceRequest request)

Returns additional metadata for a previously executed successful request, typically used for debugging issues where a service isn't acting as expected. This data isn't considered part of the result data returned by an operation, so it's available through this separate, diagnostic interface.

Response metadata is only cached for a limited period of time, so if you need to access this extra diagnostic information for an executed request, you should use this method to retrieve it as soon as possible after executing a request.

Parameters:

request - The originally executed request.

Returns:

The response metadata for the specified request, or null if none is available.
