Syntax

public static class Backoff

Methods

OnFailure(Props, string, TimeSpan, TimeSpan, double)

Back-off options for creating a back-off supervisor actor that expects a child actor to restart on failure.

Declaration

[Obsolete("Use the overloaded one which accepts maxNrOfRetries instead.")]
public static BackoffOptions OnFailure(Props childProps, string childName, TimeSpan minBackoff, TimeSpan maxBackoff, double randomFactor)

Parameters

Type	Name	Description
Props	childProps	The Props of the child actor that will be started and supervised
string	childName	Name of the child actor
TimeSpan	minBackoff	Minimum (initial) duration until the child actor will started again, if it is terminated
TimeSpan	maxBackoff	The exponential back-off is capped to this duration
double	randomFactor	After calculation of the exponential back-off an additional random delay based on this factor is added, e.g. 0.2 adds up to 20% delay. In order to skip this additional delay pass in 0.

Returns

Type	Description
BackoffOptions

OnFailure(Props, string, TimeSpan, TimeSpan, double, int)

Back-off options for creating a back-off supervisor actor that expects a child actor to restart on failure.

Declaration

public static BackoffOptions OnFailure(Props childProps, string childName, TimeSpan minBackoff, TimeSpan maxBackoff, double randomFactor, int maxNrOfRetries)

Parameters

Type	Name	Description
Props	childProps	The Props of the child actor that will be started and supervised
string	childName	Name of the child actor
TimeSpan	minBackoff	Minimum (initial) duration until the child actor will started again, if it is terminated
TimeSpan	maxBackoff	The exponential back-off is capped to this duration
double	randomFactor	After calculation of the exponential back-off an additional random delay based on this factor is added, e.g. 0.2 adds up to 20% delay. In order to skip this additional delay pass in 0.
int	maxNrOfRetries	Maximum number of attempts to restart the child actor. The supervisor will terminate itself after the maxNoOfRetries is reached. In order to restart infinitely pass in -1

Returns

Type	Description
BackoffOptions

OnStop(Props, string, TimeSpan, TimeSpan, double)
