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. |
