Detailed Description

Records the various variables associated with a reader.

This is basically a container class with a constructor that copies the current state of a given Reader.

Constructor & Destructor Documentation

§ ReaderState()

creativity::state::ReaderState::ReaderState ( const uint32_t dimensions )

explicit

Constructs a new blank ReaderState for a reader with a position of the given number of dimensions.

All values will be default initialized. (The number of dimensions is needed for Position initialization).

Member Function Documentation

§ profitExtrap()

const belief::Profit& creativity::state::ReaderState::profitExtrap ( ) const

Returns profit_extrap if it exists (i.e.

if there is extrapolated data), otherwise returns profit (i.e. if there was no extrapolated data and so profit_extrap_ is exactly the same as profit_).

§ updateLibraryCounts()

void creativity::state::ReaderState::updateLibraryCounts ( eris::eris_time_t t )

Utility method to recalculate purchased, purchased_new, pirated, and pirated_new from the current library.

Parameters

t	the time period of the state. Needed to identify newly-acquired books (books with `copy.acquired == t`
