Method Detail

build

public ExponentialBackOff build()

Builds a new instance of ExponentialBackOff.

getInitialIntervalMillis

public final int getInitialIntervalMillis()

Returns the initial retry interval in milliseconds. The default value is ExponentialBackOff.DEFAULT_INITIAL_INTERVAL_MILLIS.

setInitialIntervalMillis

public ExponentialBackOff.Builder setInitialIntervalMillis(int initialIntervalMillis)

Sets the initial retry interval in milliseconds. The default value is ExponentialBackOff.DEFAULT_INITIAL_INTERVAL_MILLIS. Must be > 0.

Overriding is only supported for the purpose of calling the super implementation and changing the return type, but nothing else.

getRandomizationFactor

public final double getRandomizationFactor()

Returns the randomization factor to use for creating a range around the retry interval. The default value is ExponentialBackOff.DEFAULT_RANDOMIZATION_FACTOR.

A randomization factor of 0.5 results in a random period ranging between 50% below and 50% above the retry interval.

Overriding is only supported for the purpose of calling the super implementation and changing the return type, but nothing else.

setRandomizationFactor

public ExponentialBackOff.Builder setRandomizationFactor(double randomizationFactor)

Sets the randomization factor to use for creating a range around the retry interval. The default value is ExponentialBackOff.DEFAULT_RANDOMIZATION_FACTOR. Must fall in the range 0 <= randomizationFactor < 1.

A randomization factor of 0.5 results in a random period ranging between 50% below and 50% above the retry interval.

Overriding is only supported for the purpose of calling the super implementation and changing the return type, but nothing else.

getMultiplier

public final double getMultiplier()

Returns the value to multiply the current interval with for each retry attempt. The default value is ExponentialBackOff.DEFAULT_MULTIPLIER.

setMultiplier

public ExponentialBackOff.Builder setMultiplier(double multiplier)

Sets the value to multiply the current interval with for each retry attempt. The default value is ExponentialBackOff.DEFAULT_MULTIPLIER. Must be >= 1.

Overriding is only supported for the purpose of calling the super implementation and changing the return type, but nothing else.

getMaxIntervalMillis

public final int getMaxIntervalMillis()

Returns the maximum value of the back off period in milliseconds. Once the current interval reaches this value it stops increasing. The default value is ExponentialBackOff.DEFAULT_MAX_INTERVAL_MILLIS. Must be >= initialInterval.

setMaxIntervalMillis

public ExponentialBackOff.Builder setMaxIntervalMillis(int maxIntervalMillis)

Sets the maximum value of the back off period in milliseconds. Once the current interval reaches this value it stops increasing. The default value is ExponentialBackOff.DEFAULT_MAX_INTERVAL_MILLIS.

Overriding is only supported for the purpose of calling the super implementation and changing the return type, but nothing else.

getMaxElapsedTimeMillis

public final int getMaxElapsedTimeMillis()

Returns the maximum elapsed time in milliseconds. The default value is ExponentialBackOff.DEFAULT_MAX_ELAPSED_TIME_MILLIS.

If the time elapsed since an ExponentialBackOff instance is created goes past the max_elapsed_time then the method ExponentialBackOff.nextBackOffMillis() starts returning this value. The elapsed time can be reset by calling ExponentialBackOff.reset().

setMaxElapsedTimeMillis

public ExponentialBackOff.Builder setMaxElapsedTimeMillis(int maxElapsedTimeMillis)

Sets the maximum elapsed time in milliseconds. The default value is ExponentialBackOff.DEFAULT_MAX_ELAPSED_TIME_MILLIS. Must be > 0.

If the time elapsed since an ExponentialBackOff instance is created goes past the max_elapsed_time then the method ExponentialBackOff.nextBackOffMillis() starts returning this value. The elapsed time can be reset by calling ExponentialBackOff.reset().
