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

MonoDelta()

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

Equals()

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.

FromMicroseconds()

static MonoDelta kudu::MonoDelta::FromMicroseconds ( int64_t  us )

static

Parameters

[in]

us

Time interval representation in seconds (with ubiquitous SI prefixes).

Returns

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

FromMilliseconds()

static MonoDelta kudu::MonoDelta::FromMilliseconds ( int64_t  ms )

static

Parameters

[in]

ms

Time interval representation in seconds (with ubiquitous SI prefixes).

Returns

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

FromNanoseconds()

static MonoDelta kudu::MonoDelta::FromNanoseconds ( int64_t  ns )

static

Parameters

[in]

ns

Time interval representation in seconds (with ubiquitous SI prefixes).

Returns

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

FromSeconds()

static MonoDelta kudu::MonoDelta::FromSeconds ( double  seconds )

static

Parameters

[in]

seconds

Time interval representation in seconds (with ubiquitous SI prefixes).

Returns

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

Initialized()

bool kudu::MonoDelta::Initialized

(

)

const

Returns

true iff this object is initialized.

LessThan()

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.

MoreThan()

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.

NanosToTimeSpec()

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.

operator+=()

MonoDelta & kudu::MonoDelta::operator+=

(

const MonoDelta &

delta

)

Add a delta to current time interval.

Parameters

[in]

delta

The delta to add.

Returns

Reference to the modified object.

operator-=()

MonoDelta & kudu::MonoDelta::operator-=

(

const MonoDelta &

delta

)

Substract a delta from current time interval.

Parameters

[in]

delta
