Constructors

ExecutionStrategy(DbContext, Int32, TimeSpan)

Creates a new instance of ExecutionStrategy.

ExecutionStrategy(ExecutionStrategyContext, Int32, TimeSpan)

Creates a new instance of ExecutionStrategy.

ExecutionStrategy(ExecutionStrategyDependencies, Int32, TimeSpan)

Creates a new instance of ExecutionStrategy.

Fields

DefaultMaxDelay

The default maximum time delay between retries, must be nonnegative.

DefaultMaxRetryCount

The default number of retry attempts.

Properties

Context

The context on which the operations will be invoked.

Dependencies

Parameter object containing service dependencies.

ExceptionsEncountered

The list of exceptions that caused the operation to be retried so far.

Logger

The logger for this ExecutionStrategy.

MaxRetryCount

The maximum number of retry attempts.

MaxRetryDelay

The maximum delay between retries.

Random

A pseudo-random number generator that can be used to vary the delay between retries.

RetriesOnFailure

Indicates whether this IExecutionStrategy might retry the execution after a failure.

Suspended

Indicates whether the strategy is suspended. The strategy is typically suspending while executing to avoid recursive execution from nested operations.

Methods

CallOnWrappedException<TResult>(Exception, Func<Exception,TResult>)

Recursively gets InnerException from exception as long as it is an exception created by Entity Framework and calls exceptionHandler on the innermost one.

Execute<TState,TResult>(Func<TState,TResult>, Func<TState,ExecutionResult<TResult>>, TState)

Executes the specified operation and returns the result.

Execute<TState,TResult>(TState, Func<DbContext,TState,TResult>, Func<DbContext,TState,ExecutionResult<TResult>>)

Executes the specified operation and returns the result.

ExecuteAsync<TState,TResult>(Func<TState,CancellationToken,Task<TResult>>, Func<TState,CancellationToken,Task<ExecutionResult<TResult>>>, TState, CancellationToken)

Executes the specified asynchronous operation and returns the result.

ExecuteAsync<TState,TResult>(TState, Func<DbContext,TState,CancellationToken,Task<TResult>>, Func<DbContext,TState,CancellationToken,Task<ExecutionResult<TResult>>>, CancellationToken)

Executes the specified asynchronous operation and returns the result.

ExecuteInTransaction<TState,TResult>(Func<TState,TResult>, Func<TState,Boolean>, TState)

Executes the specified operation in a transaction and returns the result after commiting it.

ExecuteInTransactionAsync<TState,TResult>(Func<TState,CancellationToken,Task<TResult>>, Func<TState,CancellationToken,Task<Boolean>>, TState, CancellationToken)

Executes the specified asynchronous operation and returns the result.

GetNextDelay(Exception)

Determines whether the operation should be retried and the delay before the next attempt.

OnFirstExecution()

Method called before the first operation execution

OnRetry()

Method called before retrying the operation execution

ShouldRetryOn(Exception)

Determines whether the specified exception represents a transient failure that can be compensated by a retry.

ShouldVerifySuccessOn(Exception)

Determines whether the specified exception could be thrown after a successful execution.
