Method Details

iterator

public Iterator<E> iterator()

Specified by:

iterator in interface IIterableInterval<E extends Comparable<E>,S,U,ME extends IterableInterval<E,S,U,ME>>

Specified by:

iterator in interface Iterable<E extends Comparable<E>>

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.

See Also:

• IIterableInterval.iterateFromLeft()
• IIterableInterval.iterateFromRight()

getStep

public S getStep()

Specified by:

getStep in interface IIterableInterval<E extends Comparable<E>,S,U,ME extends IterableInterval<E,S,U,ME>>

Returns:

The step (or increment) by which this interval visits elements in its set. Returns null if this interval cannot iterate its elements.

For instance, if the interval is a set of decimal values, say [1..10], the step might be a decimal increment, say 0.25. Similarly, if the interval is simply a set of integers the step might also be an integer value, typically 1. Considering a date interval, say [4/5/10..5/20/10], the step could be expressed in terms of a unit of time e.g., 10 seconds, 1 minute, 2 weeks, etc.

Note if non-null, the step is a positive (or absolute) increment. To iterate the interval in reverse order use iterateFromRight().

step

public ME step(S s)

Specified by:

step in interface IIterableInterval<E extends Comparable<E>,S,U,ME extends IterableInterval<E,S,U,ME>>

getUnit

public U getUnit()

Specified by:

getUnit in interface IIterableInterval<E extends Comparable<E>,S,U,ME extends IterableInterval<E,S,U,ME>>

unit

public ME unit(U u)

Specified by:

unit in interface IIterableInterval<E extends Comparable<E>,S,U,ME extends IterableInterval<E,S,U,ME>>

equals

public boolean equals(Object o)

Overrides:

equals in class AbstractInterval<E extends Comparable<E>,ME extends IterableInterval<E,S,U,ME>>

hashCode

public int hashCode()

Overrides:

hashCode in class AbstractInterval<E extends Comparable<E>,ME extends IterableInterval<E,S,U,ME>>

public String toString()

Overrides:

toString in class AbstractInterval<E extends Comparable<E>,ME extends IterableInterval<E,S,U,ME>>
