Detailed Description

A class to traverse the observations of a trajectory.

This class provides a mechanism to traverse the trajectory observations sequentially, ordered by time.

An example of use:

TrajectoryIterator it = tj.begin(); while(it!=tj.end()) { Geometry* g = it.getGeometry(); DateTime* t = it.getTime(); ++it; }

Constructor & Destructor Documentation

te::st::TrajectoryIterator::TrajectoryIterator

(

)

Empty constructor.

te::st::TrajectoryIterator::TrajectoryIterator

(

TrajectoryObservationSet::const_iterator &

it

)

Constructor.

Parameters

it	A iterator that points to the trajectory observations

virtual te::st::TrajectoryIterator::~TrajectoryIterator ( )

virtual

Virtual destructor.

Member Function Documentation

te::gm::Geometry* te::st::TrajectoryIterator::getGeometry

(

)

const

It returns the geometry pointed by the internal cursor.

Returns

A pointer to the geometry pointed by the internal cursor.

Note

The caller will NOT take the ownership of the returned pointer.

te::dt::DateTime* te::st::TrajectoryIterator::getTime

(

)

const

It returns the datetime pointed by the internal cursor.

Returns

A pointer to the datetime pointed by the internal cursor.

Note

The caller will NOT take the ownership of the returned pointer.

bool te::st::TrajectoryIterator::operator!=

(

const TrajectoryIterator &

rhs

)

Operator !=.

TrajectoryObservation te::st::TrajectoryIterator::operator*

(

)

const

Prefix operator *.

It returns the item (a pair of shared pointers to the geometry and time) pointed by the internal cursor.

TrajectoryIterator& te::st::TrajectoryIterator::operator++

(

)

Prefix operator ++.

After using this operator, the internal cursor points to the next trajectory observation.

The semantics of prefix is this: Increment the value and then fetch it.

TrajectoryIterator te::st::TrajectoryIterator::operator++

(

int

aux

)

Postfix operator ++.

After using this operator, the internal cursor points to the next trajectory observation.

The semantics of postfix is: Fetch the value and then increment the original.

TrajectoryIterator& te::st::TrajectoryIterator::operator--

(

)

Prefix operator –.

After using this operator, the internal cursor points to the preceding trajectory observation.

The semantics of prefix is this: Increment the value and then fetch it.

TrajectoryIterator te::st::TrajectoryIterator::operator--

(

int

aux

)

Postfix operator –.

After using this operator, the internal cursor points to the preceding trajectory observation.

The semantics of postfix is: Fetch the value and then increment the original.

const TrajectoryIterator& te::st::TrajectoryIterator::operator=

(

const TrajectoryIterator &

rhs

)

Assignment operator.

bool te::st::TrajectoryIterator::operator==

(

const TrajectoryIterator &

rhs

)

Operator ==.
