virtual MappingIterator* TimeMapping< Interpolator >::createIterator

(

const Argument &

pos

)

[inline, virtual]

Returns a pointer of a new Iterator which is able to iterate over the function and can change the value the iterator points to.

Note: The caller of this method has to delete the returned Iterator pointer if it isn't used anymore.

Implements Mapping.

const [inline, virtual]

Returns the value of this Function at the position specified by the passed Argument.

This method has logarithmic complexity.

template<template< class Key, class Value, class Pair, class Iterator > class Interpolator>

bool TimeMapping< Interpolator >::isStepMapping [protected]

Stores if this mapping represents a step function.

Assures that the steps are considered when iterating the mapping by adding a second key-entry as short as possible before every key entry set by the user. The additional key-entry defines the value the mapping has just before the key entry the user added.
