Constructor Details

RetryConfigImpl

protected RetryConfigImpl(RetryConfig.BuilderBase<?,?> builder)

Create an instance providing a builder.

Parameters:

builder - extending builder base of this prototype

Method Details

build

public Retry build()

Description copied from interface: Prototype.Factory

Create a new instance of the runtime type from this config object.

Specified by:

build in interface Prototype.Factory<Retry>

Returns:

new configured runtime instance

get

public Retry get()

Specified by:

get in interface Supplier<Retry>

name

public Optional<String> name()

Description copied from interface: RetryConfig

Name for debugging, error reporting, monitoring.

Specified by:

name in interface RetryConfig

Returns:

name of this retry

calls

public int calls()

Description copied from interface: RetryConfig

Number of calls (first try + retries).

Specified by:

calls in interface RetryConfig

Returns:

number of desired calls, must be 1 (means no retries) or higher.

delay

public Duration delay()

Description copied from interface: RetryConfig

Base delay between try and retry. Defaults to 200 ms.

Specified by:

delay in interface RetryConfig

Returns:

delay between retries (combines with retry policy)

delayFactor

public double delayFactor()

Description copied from interface: RetryConfig

Delay retry policy factor. If unspecified (value of -1), Jitter retry policy would be used, unless jitter is also unspecified.

Default when Retry.DelayingRetryPolicy is used is 2.

Specified by:

delayFactor in interface RetryConfig

Returns:

delay factor for delaying retry policy

jitter

public Duration jitter()

Description copied from interface: RetryConfig

Jitter for Retry.JitterRetryPolicy. If unspecified (value of -1), delaying retry policy is used. If both this value, and RetryConfig.delayFactor() are specified, delaying retry policy would be used.

Specified by:

jitter in interface RetryConfig

Returns:

jitter

overallTimeout

public Duration overallTimeout()

Description copied from interface: RetryConfig

Overall timeout of all retries combined.

Specified by:

overallTimeout in interface RetryConfig

Returns:

overall timeout

skipOn

public Set<Class<? extends Throwable>> skipOn()

Description copied from interface: RetryConfig

These throwables will not be considered retriable, all other will.

Specified by:

skipOn in interface RetryConfig

Returns:

throwable classes to skip retries

See Also:

• RetryConfig.applyOn()

applyOn

public Set<Class<? extends Throwable>> applyOn()

Description copied from interface: RetryConfig

These throwables will be considered retriable.

Specified by:

applyOn in interface RetryConfig

Returns:

throwable classes to trigger retries

See Also:

• RetryConfig.skipOn()

retryPolicy

public Optional<Retry.RetryPolicy> retryPolicy()

Description copied from interface: RetryConfig

Explicitly configured retry policy.

Specified by:

retryPolicy in interface RetryConfig

Returns:

retry policy

enableMetrics

public boolean enableMetrics()

Description copied from interface: RetryConfig

Flag to enable metrics for this instance. The value of this flag is combined with the global config entry FaultTolerance.FT_METRICS_DEFAULT_ENABLED. If either of these flags is true, then metrics will be enabled for the instance.

Specified by:

enableMetrics in interface RetryConfig

Returns:

metrics enabled flag

toString

public String toString()

Overrides:

toString in class Object

equals

public boolean equals(Object o)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object
