Struct Interval

An interval between two instants in time (start and end).
Since 1.0.x
Availability net35-Client, PCL

IEquatable<Interval>

Syntax
[Serializable]
public struct Interval : IEquatable<Interval>, IXmlSerializable, ISerializable
Remarks

The interval includes the start instant and excludes the end instant, unless the end instant is MaxValue in which case it's deemed to be inclusive. (An interval stretching to infinity includes the end of time.)

The end may equal the start (resulting in an empty interval), but will not be before the start.

Constructors

Interval(Instant, Instant)

Initializes a new instance of the Interval struct. The interval includes the start instant and excludes the end instant. The end may equal the start (resulting in an empty interval), but must not be before the start.
Since 1.0.x
Availability net35-Client, PCL
Declaration
public Interval(Instant start, Instant end)
Parameters
Type Name Description
Instant start The start Instant.
Instant end The end Instant.
Exceptions
Type Condition
ArgumentOutOfRangeException end is earlier than start.

Properties

Duration

Returns the duration of the interval.
Since 1.0.x
Availability net35-Client, PCL
Declaration
public Duration Duration { get; }
Property Value
Type Description
Duration The duration of the interval.
Remarks
This will always be a non-negative duration, though it may be zero.

End

Gets the end instant - the exclusive upper bound of the interval.
Since 1.0.x
Availability net35-Client, PCL
Declaration
public Instant End { get; }
Property Value
Type Description
Instant The end Instant.
Remarks
This will never be earlier than Start, though it may be equal to it. If this value is MaxValue, it is treated as an inclusive upper bound: an interval stretching to infinity includes the end of time.

Start

Gets the start instant - the inclusive lower bound of the interval.
Since 1.0.x
Availability net35-Client, PCL
Declaration
public Instant Start { get; }
Property Value
Type Description
Instant The start Instant.
Remarks
This will never be later than End, though it may be equal to it.

Methods

Contains(Instant)

Returns whether or not this interval contains the given instant.
Since 1.2.x
Availability net35-Client, PCL
Declaration
public bool Contains(Instant instant)
Parameters
Type Name Description
Instant instant Instant to test.
Returns
Type Description
Boolean True if this interval contains the given instant; false otherwise.
Remarks
The interval is considered to include the Start instant but not the End instant - unless the end is MaxValue, in which case it's considered to be infinite from the start point onwards.

Equals(Interval)

Indicates whether the value of this interval is equal to the value of the specified interval.
Since 1.0.x
Availability net35-Client, PCL
Declaration
public bool Equals(Interval other)
Parameters
Type Name Description
Interval other The value to compare with this instance.
Returns
Type Description
Boolean true if the value of this instant is equal to the value of the other parameter; otherwise, false.

Equals(Object)

Determines whether the specified System.Object is equal to this instance.
Since 1.0.x
Availability net35-Client, PCL
Declaration
public override bool Equals(object obj)
Parameters
Type Name Description
Object obj The System.Object to compare with this instance.
Returns
Type Description
Boolean true if the specified System.Object is equal to this instance; otherwise, false.
Overrides
System.ValueType.Equals(System.Object)

GetHashCode()

Returns the hash code for this instance.
Since 1.0.x
Availability net35-Client, PCL
Declaration
public override int GetHashCode()
Returns
Type Description
Int32 A 32-bit signed integer that is the hash code for this instance.
Overrides
System.ValueType.GetHashCode()

ToString()

Returns a string representation of this interval, in extended ISO-8601 format: the format is "start/end" where each instant uses a format of "yyyy'-'MM'-'dd'T'HH':'mm':'ss;FFFFFFF'Z'".
Since 1.0.x
Availability net35-Client, PCL
Declaration
public override string ToString()
Returns
Type Description
String A string representation of this interval.
Overrides
System.ValueType.ToString()

Operators

Equality(Interval, Interval)

Implements the operator ==.
Since 1.0.x
Availability net35-Client, PCL
Declaration
public static bool operator ==(Interval left, Interval right)
Parameters
Type Name Description
Interval left The left.
Interval right The right.
Returns
Type Description
Boolean The result of the operator.

Inequality(Interval, Interval)

Implements the operator !=.
Since 1.0.x
Availability net35-Client, PCL
Declaration
public static bool operator !=(Interval left, Interval right)
Parameters
Type Name Description
Interval left The left.
Interval right The right.
Returns
Type Description
Boolean The result of the operator.
