Class OperationResourcePollingStrategy<T,U>

java.lang.Object

com.azure.core.util.polling.OperationResourcePollingStrategy<T,U>

Type Parameters:

T - the type of the response type from a polling call, or BinaryData if raw response body should be kept

U - the type of the final result object to deserialize into, or BinaryData if raw response body should be kept

All Implemented Interfaces:

PollingStrategy<T,U>

public class OperationResourcePollingStrategy<T,U>
extends Object
implements PollingStrategy<T,U>

Implements a operation resource polling strategy, typically from Operation-Location.

Constructor Summary

Constructors

Constructor	Description
OperationResourcePollingStrategy(HttpPipeline httpPipeline)	Creates an instance of the operation resource polling strategy using a JSON serializer and "Operation-Location" as the header for polling.
OperationResourcePollingStrategy(HttpPipeline httpPipeline, ObjectSerializer serializer, String operationLocationHeaderName)	Creates an instance of the operation resource polling strategy.

Method Summary

Modifier and Type	Method	Description
Mono<Boolean>	canPoll(Response<?> initialResponse)	Checks if this strategy is able to handle polling for this long running operation based on the information in the initial response.
Mono<U>	getResult(PollingContext<T> pollingContext, TypeReference<U> resultType)	Parses the response from the final GET call into the result type of the long running operation.
Mono<PollResponse<T>>	onInitialResponse(Response<?> response, PollingContext<T> pollingContext, TypeReference<T> pollResponseType)	Parses the initial response into a LongRunningOperationStatus, and stores information useful for polling in the PollingContext.
Mono<PollResponse<T>>	poll(PollingContext<T> pollingContext, TypeReference<T> pollResponseType)	Parses the response from the polling URL into a PollResponse, and stores information useful for further polling and final response in the PollingContext.

Constructor Detail

OperationResourcePollingStrategy

public OperationResourcePollingStrategy(HttpPipeline httpPipeline)

Creates an instance of the operation resource polling strategy using a JSON serializer and "Operation-Location" as the header for polling.

Parameters:

httpPipeline - an instance of HttpPipeline to send requests with

OperationResourcePollingStrategy

public OperationResourcePollingStrategy(HttpPipeline httpPipeline,
                                        ObjectSerializer serializer,
                                        String operationLocationHeaderName)

Creates an instance of the operation resource polling strategy.

Parameters:

httpPipeline - an instance of HttpPipeline to send requests with

serializer - a custom serializer for serializing and deserializing polling responses

operationLocationHeaderName - a custom header for polling the long running operation

Method Detail

canPoll

public Mono<Boolean> canPoll(Response<?> initialResponse)

Description copied from interface: PollingStrategy

Checks if this strategy is able to handle polling for this long running operation based on the information in the initial response.

Specified by:

canPoll in interface PollingStrategy<T,U>

Parameters:

initialResponse - the response from the initial method call to activate the long running operation

Returns:

true if this polling strategy can handle the initial response, false if not

onInitialResponse

public Mono<PollResponse<T>> onInitialResponse(Response<?> response,
                                               PollingContext<T> pollingContext,
                                               TypeReference<T> pollResponseType)

Description copied from interface: PollingStrategy

Parses the initial response into a LongRunningOperationStatus, and stores information useful for polling in the PollingContext. If the result is anything other than LongRunningOperationStatus.IN_PROGRESS, the long running operation will be terminated and none of the other methods will be invoked.

Specified by:

onInitialResponse in interface PollingStrategy<T,U>

Parameters:

response - the response from the initial method call to activate the long running operation

pollingContext - the PollingContext for the current polling operation

pollResponseType - the TypeReference of the response type from a polling call, or BinaryData if raw response body should be kept. This should match the generic parameter PollingStrategy.

Returns:

a publisher emitting the poll response containing the status and the response content

poll

public Mono<PollResponse<T>> poll(PollingContext<T> pollingContext,
                                  TypeReference<T> pollResponseType)

Description copied from interface: PollingStrategy

Parses the response from the polling URL into a PollResponse, and stores information useful for further polling and final response in the PollingContext. The result must have the LongRunningOperationStatus specified, and the entire polling response content as a BinaryData.

Specified by:

poll in interface PollingStrategy<T,U>

Parameters:

pollingContext - the PollingContext for the current polling operation

pollResponseType - the TypeReference of the response type from a polling call, or BinaryData if raw response body should be kept. This should match the generic parameter PollingStrategy.

Returns:

a publisher emitting the poll response containing the status and the response content

getResult

public Mono<U> getResult(PollingContext<T> pollingContext,
                         TypeReference<U> resultType)

Description copied from interface: PollingStrategy

Parses the response from the final GET call into the result type of the long running operation.

Specified by:

getResult in interface PollingStrategy<T,U>

Parameters:

pollingContext - the PollingContext for the current polling operation

resultType - the TypeReference of the final result object to deserialize into, or BinaryData if raw response body should be kept.

Returns:

a publisher emitting the final result
