Syntax

public static class TimeSpanExtensions

Methods

GetSeconds(TimeSpan)

Retrieves the number of seconds expressed in a TimeSpan as an uint.

Declaration

public static uint GetSeconds(this TimeSpan timeSpan)

Parameters

Type	Name	Description
TimeSpan	timeSpan	The timespan.

Returns

Type	Description
uint	An uint that is the total number of seconds in the TimeSpan.

RemainingTtl(DateTimeOffset)

Converts an absolute expiry DateTimeOffset back to the remaining TimeSpan relative to now. Returns a minimum of 1 second to avoid passing 0 to the server, which would mean "never expire".

Declaration

public static TimeSpan RemainingTtl(this DateTimeOffset absoluteExpiry)

Parameters

Type	Name	Description
DateTimeOffset	absoluteExpiry	The absolute expiry time.

Returns

Type	Description
TimeSpan	The remaining TTL as a TimeSpan, minimum 1 second.

ToEpochTtl(TimeSpan)

Converts a relative TimeSpan duration to an absolute DateTimeOffset representing when the TTL should expire. Used by transactions to capture the expiry time at staging, so the TTL clock starts from staging rather than unstaging.

Declaration

public static DateTimeOffset ToEpochTtl(this TimeSpan duration)

Parameters

Type	Name	Description
TimeSpan	duration	The relative TTL duration.

Returns

Type	Description
DateTimeOffset	An absolute DateTimeOffset representing the expiry time.

ToTtl(TimeSpan)

Converts a TimeSpan into an uint correctly representing a Time-To-Live, that is expressed in seconds. Durations strictly bigger than 30 days are converted to a unix-syle timestamp (seconds since the Epoch), as described in the couchbase TTL documentation.

Declaration

public static uint ToTtl(this TimeSpan duration)

Parameters

Type	Name	Description
TimeSpan	duration

Returns

Type	Description
uint	The TTL, expressed as a suitable uint.

ToTtl(uint)

Converts a duration expressed as milliseconds to a unix-based TTL.

Declaration

public static uint ToTtl(this uint duration)

Parameters

Type	Name	Description
uint	duration	Milliseconds to use as TTL.

Returns

Type	Description
uint	The TTL, expressed as a unix-based TTL in milliseconds.
