Constructor Details

FibonacciPollInterval

public FibonacciPollInterval()

Create an instance of the FibonacciPollInterval with the time unit of TimeUnit.MILLISECONDS.

FibonacciPollInterval

public FibonacciPollInterval(TimeUnit unit)

Create an instance of the FibonacciPollInterval with the supplied time unit starting with offset equal to 0.

Parameters:

unit - The time unit

See Also:

• FibonacciPollInterval(int, TimeUnit)

FibonacciPollInterval

public FibonacciPollInterval(int offset,
 TimeUnit unit)

Create an instance of the FibonacciPollInterval with a supplied time unit.

Parameters:

offset - The fibonacci offset. For example if offset is 5 and poll count is 1 then the returned duration will be 8 (since fib(6) is equal to 8). Default offset is 0. You can set the offset to -1 if you want the first value to be fib(0) (i.e. pollCount - offset). By default the first value will be fib(1).

unit - The time unit

Method Details

next

public Duration next(int pollCount,
 Duration previousDuration)

Generate the next duration

Specified by:

next in interface PollInterval

Parameters:

pollCount - The number of times the condition has been polled (evaluated)

previousDuration - The duration of the previously returned poll interval

Returns:

The next duration in the fibonacci sequence.

fibonacci

public static FibonacciPollInterval fibonacci()

Syntactic sugar for new FibonacciPollInterval()

Returns:

A new instance of FibonacciPollInterval.

fibonacci

public static FibonacciPollInterval fibonacci(TimeUnit unit)

Syntactic sugar for new FibonacciPollInterval(unit)

Parameters:

unit - The time unit

Returns:

A new instance of FibonacciPollInterval.

fibonacci

public static FibonacciPollInterval fibonacci(int offset,
 TimeUnit unit)

Syntactic sugar for new FibonacciPollInterval(offset, unit)

Parameters:

offset - The fibonacci offset. For example if offset is 5 and poll count is 1 then the returned duration will be 8 (since fib(6) is equal to 8). Default offset is 0.

unit - The time unit

Returns:

A new instance of FibonacciPollInterval.
