Method Details

iterateFromLeft

public Iterator<Date> iterateFromLeft()

Returns:

An iterator that visits the elements in this interval in order, from left to right. Returns null if this interval does not support iteration.

• IIterableInterval.iterator()
• IIterableInterval.iterateFromRight()

iterateFromRight

public Iterator<Date> iterateFromRight()

Returns:

An iterator that visits the elements in this interval in reverse order, from right to left. Returns null if this interval does not support iteration.

See Also:

• IIterableInterval.iterator()
• IIterableInterval.iterateFromLeft()

add

private Date add(Date date)

add

private Date add(Date date,
 int iMultiple)

subtract

private Date subtract(Date date)

subtract

private Date subtract(Date date,
 int iMultiple)

getFromLeft

public Date getFromLeft(int iStepIndex)

Parameters:

iStepIndex - The index of the step from the left endpoint

Returns:

The nth step from the left endpoint. Returns null if iStepIndex is out of bounds.

getFromRight

public Date getFromRight(int iStepIndex)

Parameters:

iStepIndex - The index of the step from the right endpoint

Returns:

The nth step from the right endpoint. Returns null if iStepIndex is out of bounds.
