Constructor Detail

IntervalSet

public IntervalSet()

Default constructor.

The set is empty with zero capacity.

IntervalSet

public IntervalSet(int capacity)

Constructor with capacity.

Using this constructor can improve performances if the number of intervals is known in advance as it minimizes array resizes.

Parameters:

capacity - interval capacity

IntervalSet

public IntervalSet(double[] arr)

Constructor with an initial interval set.

The given array must be sorted and containing an even number of elements.

Parameters:

arr - initial set content

Method Detail

add

public boolean add(Interval interval)

Description copied from interface: TimeSet

Adds key to this set.

Specified by:

add in interface TimeSet<Interval>

Parameters:

interval - key

Returns:

true if added, false otherwise

remove

public boolean remove(Interval interval)

Description copied from interface: TimeSet

Removes key from this set.

Specified by:

remove in interface TimeSet<Interval>

Parameters:

interval - key

Returns:

true if removed, false otherwise

size

public int size()

Description copied from interface: TimeSet

Returns the size of this set.

Specified by:

size in interface TimeSet<Interval>

Returns:

the number of elements in this set

isEmpty

public boolean isEmpty()

Description copied from interface: TimeSet

Returns true if this set is empty.

Specified by:

isEmpty in interface TimeSet<Interval>

Returns:

true if empty, false otherwise

contains

public boolean contains(double timestamp)

Returns true if this set contains an interval that starts or ends at timestamp.

Parameters:

timestamp - timestamp

Returns:

true if contains, false otherwise

contains

public boolean contains(Interval interval)

Description copied from interface: TimeSet

Returns true if this set contains key.

Specified by:

contains in interface TimeSet<Interval>

Parameters:

interval - key

Returns:

true if contains, false otherwise

getIntervals

public double[] getIntervals()

Returns an array of all intervals in this set in a flat format.

The intervals are represented in a flat and sorted array (e.g. {[1.0,2.0], [5.0,6.0]}) returns [1.0,2.0,5.0,6.0]).

This method may return a reference to the underlying array so clients should make a copy if the array is written to.

Returns:

array of all intervals

toArray

public Interval[] toArray()

Description copied from interface: TimeSet

Returns an array of all keys in this set.

This method may return a reference to the underlying array so clients should make a copy if the array is written to.

Specified by:

toArray in interface TimeSet<Interval>

Returns:

array of all keys

toPrimitiveArray

public Object toPrimitiveArray()

Description copied from interface: TimeSet

Returns the same result as TimeSet.toArray() but in a primitive array if the underlying storage is in a primtive form.

Specified by:

toPrimitiveArray in interface TimeSet<Interval>

Returns:

array of all keys

clear

public void clear()

Description copied from interface: TimeSet

Empties this set.

Specified by:

clear in interface TimeSet<Interval>

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object obj)

Overrides:

equals in class Object

toString

public String toString(TimeFormat timeFormat,
                       org.joda.time.DateTimeZone timeZone)

toString

public String toString(TimeFormat timeFormat)

toString

public String toString()

Overrides:

toString in class Object
