Method Detail

empty

Ranges<T> empty()

A range of size 0L starting at this instance start time

Returns:

empty range

plus

Ranges<T> plus(Ranges<T> right)

Add 2 ranges

Parameters:

right - right operand

Returns:

sum of ranges

intersect

Ranges<T> intersect(Ranges<T> right)

Get the common range between 2 ranges. No restrictions.

Parameters:

right - right operand

Returns:

the common range or the empty range if the ranges do not intersect.

size

T size()

Returns:

range size

shift

Ranges<T> shift(T offset)

Parameters:

offset - offset to shift

Returns:

shift start and end by the same positive or negative value

end

T end()

Returns:

end

start

T start()

Returns:

start

minus

Ranges<T> minus(Ranges<T> right)

filter range: exclude a range from current range Note: does not support excluding a range that would result in more than one range.

Parameters:

right - excluded range

Returns:

part of this range that does not include right

getRanges

java.util.Collection<? extends Ranges<T>> getRanges()

Returns:

a collection of range objects [ only subclasses of Ranges ]

isEmpty

boolean isEmpty()

Returns:

whether this object is an empty range

contains

boolean contains(T value)

Whether an instant is within the range boundaries (lower bound is inclusive, upper bound is exclusive)

Parameters:

value - instant

Returns:

true if instant time is within range, false otherwise

equals

boolean equals(java.lang.Object o)

Overrides:

equals in class java.lang.Object

hashCode

int hashCode()

Overrides:

hashCode in class java.lang.Object

toRangesString

java.lang.String toRangesString()

Returns:

string representation of the ranges
