Parameters

[in] seconds/ms/us/ns Time interval representation in seconds (with ubiquitous SI prefixes).

Returns: The resulting MonoDelta object initialized in accordance with the specified parameter.

Detailed Description

A representation of a time interval.

The MonoDelta class represents an elapsed duration of time – i.e. the delta between two MonoTime instances.

Constructor & Destructor Documentation

kudu::MonoDelta::MonoDelta ( )

Build a MonoDelta object.

Note: A MonoDelta instance built with the this default constructor is "uninitialized" and may not be used for any operation.

Member Function Documentation

bool kudu::MonoDelta::Equals ( const MonoDelta & rhs ) const

Check whether this time interval has the same duration as the specified one.

Parameters

[in] rhs A time interval for comparison.

Returns: true iff this time interval has the same duration as the the specified one.

bool kudu::MonoDelta::Initialized ( ) const

Returns: true iff this object is initialized.

bool kudu::MonoDelta::LessThan ( const MonoDelta & rhs ) const

Check whether this time interval is shorter than the specified one.

Parameters

[in] rhs A time interval for comparison.

Returns: true iff this time interval is strictly shorter than the specified one.

bool kudu::MonoDelta::MoreThan ( const MonoDelta & rhs ) const

Check whether this time interval is longer than the specified one.

Parameters

[in] rhs A time interval for comparison.

Returns: true iff this time interval is strictly longer than the specified one.

static void kudu::MonoDelta::NanosToTimeSpec	(	int64_t	nanos,
		struct timespec *	ts
	)

static

Convert a nanosecond value to a timespec.

Parameters

[in]	nanos	Representation of a relative point in time in nanoseconds.
[out]	ts	Placeholder for the resulting timespec representation.

std::string kudu::MonoDelta::ToString ( ) const

Returns: String representation of this interval's duration (in seconds).

void kudu::MonoDelta::ToTimeSpec ( struct timespec * ts ) const

Represent this time interval as a timespec structure, with nanosecond accuracy.

Parameters

[out] ts Placeholder for the result value.

void kudu::MonoDelta::ToTimeVal ( struct timeval * tv ) const

Represent this time interval as a timeval structure, with microsecond accuracy.

Parameters

[out] tv Placeholder for the result value.
