Syntax

public static class Resolvers

Remarks

This class contains predefined implementations of ZoneLocalMappingResolver, AmbiguousTimeResolver, and SkippedTimeResolver, along with CreateMappingResolver(AmbiguousTimeResolver, SkippedTimeResolver), which produces a ZoneLocalMappingResolver from instances of the other two.

Fields

LenientResolver

A ZoneLocalMappingResolver which never throws an exception due to ambiguity or skipped time.

Since 1.0.x

Availability net35-Client, PCL

Declaration

public static readonly ZoneLocalMappingResolver LenientResolver

Field Value

Type	Description
ZoneLocalMappingResolver

Remarks

Ambiguity is handled by returning the later occurrence, and skipped times are mapped to the start of the zone interval after the gap. This resolver combines ReturnLater and ReturnStartOfIntervalAfter.

ReturnEarlier

An AmbiguousTimeResolver which returns the earlier of the two matching times.

Since 1.0.x

Availability net35-Client, PCL

Declaration

public static readonly AmbiguousTimeResolver ReturnEarlier

Field Value

Type	Description
AmbiguousTimeResolver

ReturnEndOfIntervalBefore

A SkippedTimeResolver which returns the final tick of the time zone interval before the "gap".

Since 1.0.x

Availability net35-Client, PCL

Declaration

public static readonly SkippedTimeResolver ReturnEndOfIntervalBefore

Field Value

Type	Description
SkippedTimeResolver

ReturnLater

An AmbiguousTimeResolver which returns the later of the two matching times.

Since 1.0.x

Availability net35-Client, PCL

Declaration

public static readonly AmbiguousTimeResolver ReturnLater

Field Value

Type	Description
AmbiguousTimeResolver

ReturnStartOfIntervalAfter

A SkippedTimeResolver which returns the first tick of the time zone interval after the "gap".

Since 1.0.x

Availability net35-Client, PCL

Declaration

public static readonly SkippedTimeResolver ReturnStartOfIntervalAfter

Field Value

Type	Description
SkippedTimeResolver

StrictResolver

A ZoneLocalMappingResolver which only ever succeeds in the (usual) case where the result of the mapping is unambiguous.

Since 1.0.x

Availability net35-Client, PCL

Declaration

public static readonly ZoneLocalMappingResolver StrictResolver

Field Value

Type	Description
ZoneLocalMappingResolver

Remarks

If the mapping is ambiguous or skipped, this throws SkippedTimeException or AmbiguousTimeException, as appropriate. This resolver combines ThrowWhenAmbiguous and ThrowWhenSkipped.

AtStrictly(LocalDateTime)

ThrowWhenAmbiguous

An AmbiguousTimeResolver which simply throws an AmbiguousTimeException.

Since 1.0.x

Availability net35-Client, PCL

Declaration

public static readonly AmbiguousTimeResolver ThrowWhenAmbiguous

Field Value

Type	Description
AmbiguousTimeResolver

ThrowWhenSkipped

A SkippedTimeResolver which simply throws a SkippedTimeException.

Since 1.0.x

Availability net35-Client, PCL

Declaration

public static readonly SkippedTimeResolver ThrowWhenSkipped

Field Value

Type	Description
SkippedTimeResolver

Methods

CreateMappingResolver(AmbiguousTimeResolver, SkippedTimeResolver)

Combines an AmbiguousTimeResolver and a SkippedTimeResolver to create a ZoneLocalMappingResolver.

Since 1.0.x

Availability net35-Client, PCL

Declaration

public static ZoneLocalMappingResolver CreateMappingResolver(AmbiguousTimeResolver ambiguousTimeResolver, SkippedTimeResolver skippedTimeResolver)

Parameters

Type	Name	Description
AmbiguousTimeResolver	ambiguousTimeResolver	Resolver to use for ambiguous mappings.
SkippedTimeResolver	skippedTimeResolver	Resolver to use for "skipped" mappings.

Returns

Type	Description
ZoneLocalMappingResolver	The logical combination of the two resolvers.

Remarks

The ZoneLocalMappingResolver created by this method operates in the obvious way: unambiguous mappings are returned directly, ambiguous mappings are delegated to the given AmbiguousTimeResolver, and "skipped" mappings are delegated to the given SkippedTimeResolver.

Exceptions

Type	Condition
ArgumentNullException	ambiguousTimeResolver or skippedTimeResolver is null
