Method Details

newDecorator

public static Function<? super RpcClient,RetryingRpcClient> newDecorator(RetryRuleWithContent<RpcResponse> retryRuleWithContent)

Creates a new RpcClient decorator that handles failures of an invocation and retries RPC requests.

Parameters:

retryRuleWithContent - the retry rule

newDecorator

@Deprecated
public static Function<? super RpcClient,RetryingRpcClient> newDecorator(RetryRuleWithContent<RpcResponse> retryRuleWithContent,
int maxTotalAttempts)

Deprecated.

Use newDecorator(RetryConfig) instead.

Creates a new RpcClient decorator that handles failures of an invocation and retries RPC requests.

Parameters:

retryRuleWithContent - the retry rule

maxTotalAttempts - the maximum number of total attempts

newDecorator

@Deprecated
public static Function<? super RpcClient,RetryingRpcClient> newDecorator(RetryRuleWithContent<RpcResponse> retryRuleWithContent,
int maxTotalAttempts,
long responseTimeoutMillisForEachAttempt)

Deprecated.

Use newDecorator(RetryConfig) instead.

Creates a new RpcClient decorator that handles failures of an invocation and retries RPC requests.

Parameters:

retryRuleWithContent - the retry rule

maxTotalAttempts - the maximum number of total attempts

responseTimeoutMillisForEachAttempt - response timeout for each attempt. 0 disables the timeout

newDecorator

public static Function<? super RpcClient,RetryingRpcClient> newDecorator(RetryConfig<RpcResponse> retryConfig)

Creates a new RpcClient decorator that handles failures of an invocation and retries RPC requests. The RetryConfig object encapsulates RetryRuleWithContent, maxContentLength, maxTotalAttempts and responseTimeoutMillisForEachAttempt.

newDecorator

public static Function<? super RpcClient,RetryingRpcClient> newDecorator(RetryConfigMapping<RpcResponse> mapping)

Creates a new RpcClient decorator that handles failures of an invocation and retries RPC requests.

Parameters:

mapping - the mapping that returns a RetryConfig for a given ClientRequestContext and Request.

builder

public static RetryingRpcClientBuilder builder(RetryRuleWithContent<RpcResponse> retryRuleWithContent)

Returns a new RetryingRpcClientBuilder with the specified RetryRuleWithContent.

builder

public static RetryingRpcClientBuilder builder(RetryConfig<RpcResponse> retryConfig)

Returns a new RetryingRpcClientBuilder with the specified RetryConfig. The RetryConfig encapsulates RetryRuleWithContent, maxContentLength, maxTotalAttempts and responseTimeoutMillisForEachAttempt.

builder

public static RetryingRpcClientBuilder builder(RetryConfigMapping<RpcResponse> mapping)

Returns a new RetryingRpcClientBuilder with the specified RetryConfigMapping.

doExecute

protected RpcResponse doExecute(ClientRequestContext ctx,
RpcRequest req)
                         throws Exception

Description copied from class: AbstractRetryingClient

Invoked by AbstractRetryingClient.execute(ClientRequestContext, Request) after the deadline for response timeout is set.

Specified by:

doExecute in class AbstractRetryingClient<RpcRequest,RpcResponse>

Throws:

Exception
