Member Function Documentation

GetLastValue()

template<typename T >

std::optional< T > wpi::log::DataLogValueEntryImpl< T >::GetLastValue ( ) const

inline

Gets the last value.

Note

The last value is local to this class instance and updated only with Update(), not Append().

Returns

Last value (empty if no last value)

HasLastValue()

template<typename T >

bool wpi::log::DataLogValueEntryImpl< T >::HasLastValue ( ) const

inline

Gets whether there is a last value.

Note

The last value is local to this class instance and updated only with Update(), not Append().

Returns

True if last value exists, false otherwise.
