Method Detail

between

public static Interval between(long startMs,
                               long endMs)

Parameters:

startMs - the start of the interval, in ms

endMs - the end of the interval, in ms

Returns:

the Interval instance, representing the interval between the start and end

before

public static Interval before(long endMs)

Parameters:

endMs - the end of the interval, in ms

Returns:

the Interval instance, representing the interval before the end

after

public static Interval after(long startMs)

Parameters:

startMs - the start of the interval, in ms

Returns:

the Interval instance, representing the interval after the start

getStartMs

public long getStartMs()

Returns:

the start of the interval, in ms

getEndMs

public long getEndMs()

Returns:

the end of the interval, in ms

isValid

public boolean isValid()

Returns:

if the interval is valid/possible

intersect

public Interval intersect(Interval other)

Parameters:

other - the other Interval

Returns:

a new interval which represents the intersection with the other interval

negate

public IntervalSet negate()

Returns:

an IntervalSet which represent the negation of this interval

add

public Interval add(long value)

Add an offset to the interval. Endpoints with MIN_VALUE and MAX_VALUE will not change.

Parameters:

value - the value to add

Returns:

the new interval with the offset

Throws:

ArithmeticException - if the result overflows

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object o)

Overrides:

equals in class Object

compareTo

public int compareTo(Interval o)

Specified by:

compareTo in interface Comparable<Interval>

toString

public String toString()

Overrides:

toString in class Object
