Detailed Description

This class implements an enhanced piecewise linear function with periodicity.

and possibility to add another arbitrary time function.

The function is defined by 'numberOfPoints' points. 'dates' and 'values' store respectively the abscissas (t) and the values (f(t)) of the points The values are repeated after 'period'. 'AddTF' parameter specifies number of function to add.

IRResultType oofem::PeriodicPiecewiseLinFunction::initializeFrom ( InputRecord * ir )

virtual

Initializes receiver according to object description stored in input record.

This function is called immediately after creating object using constructor. Input record can be imagined as data record in component database belonging to receiver. Receiver may use value-name extracting functions to extract particular field from record.
