Detailed Description

Function Documentation

GetStringFromType()

std::string_view nt::GetStringFromType

(

NT_Type

type

)

Turns a type enum value into a type string.

Parameters

type

type enum

Returns

Type string

GetTypeFromString()

NT_Type nt::GetTypeFromString

(

std::string_view

typeString

)

Turns a type string into a type enum value.

Parameters

typeString

type string

Returns

Type value

Now()

int64_t nt::Now

(

)

Returns monotonic current time in 1 us increments.

This is the same time base used for value and connection timestamps. This function by default simply wraps wpi::Now(), but if SetNow() is called, this function instead returns the value passed to SetNow(); this can be used to reduce overhead.

Returns

Timestamp

SetNow()

void nt::SetNow

(

int64_t

timestamp

)

Sets the current timestamp used for timestamping values that do not provide a timestamp (e.g.

a value of 0 is passed). For consistency, it also results in Now() returning the set value. This should generally be used only if the overhead of calling wpi::Now() is a concern. If used, it should be called periodically with the value of wpi::Now().

Parameters

timestamp

timestamp (1 us increments)
