Constructor Detail

TimestampSet

public TimestampSet()

Default constructor.

The set is empty with zero capacity.

TimestampSet

public TimestampSet(int capacity)

Constructor with capacity.

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

Parameters:

capacity - timestamp capacity

TimestampSet

public TimestampSet(double[] arr)

Constructor with an initial timestamp set.

The given array must be sorted and contain no duplicates.

Parameters:

arr - initial set content

Method Detail

add

public boolean add(Double timestamp)

Description copied from interface: TimeSet

Adds key to this set.

Specified by:

add in interface TimeSet<Double>

Parameters:

timestamp - key

Returns:

true if added, false otherwise

remove

public boolean remove(Double timestamp)

Description copied from interface: TimeSet

Removes key from this set.

Specified by:

remove in interface TimeSet<Double>

Parameters:

timestamp - 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<Double>

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<Double>

Returns:

true if empty, false otherwise

getMax

public Double getMax()

Description copied from interface: TimeSet

Returns the maximum key in the set

Specified by:

getMax in interface TimeSet<Double>

Returns:

maximum key, or null if the set is empty.

getMin

public Double getMin()

Description copied from interface: TimeSet

Returns the minimum key in the set

Specified by:

getMin in interface TimeSet<Double>

Returns:

minimum key, or null if the set is empty.

getMaxDouble

public Double getMaxDouble()

Description copied from interface: TimeSet

Returns the maximum timestamp in the set

Specified by:

getMaxDouble in interface TimeSet<Double>

Returns:

maximum timestamp, or null if the set is empty.

getMinDouble

public Double getMinDouble()

Description copied from interface: TimeSet

Returns the minimum timestamp in the set

Specified by:

getMinDouble in interface TimeSet<Double>

Returns:

minimum timestamp, or null if the set is empty.

contains

public boolean contains(Double timestamp)

Description copied from interface: TimeSet

Returns true if this set contains key.

Specified by:

contains in interface TimeSet<Double>

Parameters:

timestamp - key

Returns:

true if contains, false otherwise

toArray

public Double[] 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<Double>

Returns:

array of all keys

toPrimitiveArray

public double[] 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 primitive form.

Specified by:

toPrimitiveArray in interface TimeSet<Double>

Returns:

array of all keys

clear

public void clear()

Description copied from interface: TimeSet

Empties this set.

Specified by:

clear in interface TimeSet<Double>

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)

Description copied from interface: TimeSet

Returns this set as a string.

Specified by:

toString in interface TimeSet<Double>

Parameters:

timeFormat - time format

timeZone - time zone

Returns:

set as string

toString

public String toString(TimeFormat timeFormat)

Description copied from interface: TimeSet

Returns this set as a string.

Specified by:

toString in interface TimeSet<Double>

Parameters:

timeFormat - time format

Returns:

set as string

toString

public String toString()

Overrides:

toString in class Object
