Detailed Description

template<class T, class Container = std::map<Date, T>>
class QuantLib::TimeSeries< T, Container >

Container for historical data.

This class acts as a generic repository for a set of historical data. Any single datum can be accessed through its date, while sets of consecutive data can be accessed through iterators.

Precondition

The Container type must satisfy the requirements set by the C++ standard for associative containers.

TimeSeries ( )

default

Default constructor

TimeSeries() [2/3]

TimeSeries	(	DateIterator	dBegin,
		DateIterator	dEnd,
		ValueIterator	vBegin
	)

This constructor initializes the history with a set of values passed as two sequences, the first containing dates and the second containing corresponding values.

Definition at line 65 of file timeseries.hpp.

TimeSeries() [3/3]

TimeSeries	(	const Date &	firstDate,
		ValueIterator	begin,
		ValueIterator	end
	)

This constructor initializes the history with a set of values. Such values are assigned to a corresponding number of consecutive dates starting from firstDate included.
