Interface IMovingAverage<TYPE>

Type Parameters:

TYPE -

All Known Implementing Classes:

MovingAverage

public interface IMovingAverage<TYPE>

Represents interface to the moving average value.

Method Summary

void	add(TYPE item) Add another item into the moving average.
TYPE	getAverage() Returns an average of all items stored.
int	getCurrentLength() Return current number of items that are used to compute the average returned via getAverage().
int	getMaxLength() Return max number of consecutive items (added via add(Object) that are used to compute the average returned via getAverage().
boolean	isEnoughValues() Whether the object has enough values to compute the avarage according to the max numbers it may store (returns getCurrentLength() == getMaxLength().
void	reset() Resets the object -> it removes all items stored.
void	setMaxLength(int length) Sets number of items that the object requires for the computing of the average.

Method Detail

add

void add(TYPE item)

Add another item into the moving average.

Parameters:

item -

getAverage

TYPE getAverage()

Returns an average of all items stored.

Returns null if no values are stored.

Returns:

getCurrentLength

int getCurrentLength()

Return current number of items that are used to compute the average returned via getAverage().

Returns:

getMaxLength

int getMaxLength()

Return max number of consecutive items (added via add(Object) that are used to compute the average returned via getAverage().

Returns:

setMaxLength

void setMaxLength(int length)

Sets number of items that the object requires for the computing of the average. (Note that computation is done all the time, but when there is enough items == set number, the isEnoughValues() reports true.)

Parameters:

length -

isEnoughValues

boolean isEnoughValues()

Whether the object has enough values to compute the avarage according to the max numbers it may store (returns getCurrentLength() == getMaxLength().

reset

void reset()

Resets the object -> it removes all items stored. The getAverage() will return null after the call.
