java.lang.Object

de.tsl2.nano.util.operation.Range<T>

de.tsl2.nano.util.operation.CRange<T>

All Implemented Interfaces:

IRange<T>, Serializable, Comparable<CRange<T>>

public class CRange<T extends Comparable<T>>
extends Range<T>
implements Comparable<CRange<T>>, Serializable, IRange<T>

Constructor Detail

CRange

public CRange(T from,
              T to,
              C converter)

constructor

Parameters:

from - minimum value. if null, the converters minimum will be used

to - maximum value. if null, the converters maximum will be used

converter - (optional) object to long converter to represent an object as number value.

Method Detail

compareTo

public int compareTo(CRange<T> o)

Specified by:

compareTo in interface Comparable<CRange<T extends Comparable<T>>>

getDelta

public Number getDelta()

Calculates the span between from and to

Returns:

the span between from and to.

contains

public boolean contains(T another)

checks, if given value is inside range

Parameters:

another - value

Returns:

true, if another value is inside range

contains

public boolean contains(IRange<T> another)

Check if this period includes another one.

Parameters:

period - the period that is checked as included

Returns:

true if included

intersects

public boolean intersects(IRange<T> range)

Determines if a given period intersects the range.

Parameters:

range - range

Returns:

true if the given range intersects the current range

intersects

public boolean intersects(T from,
                          T to)

Another variant of intersection check (save range construction).

Parameters:

from - from value of other range

to - to value of other range

Returns:

true if there is an intersection
