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; }

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.

Definition at line 89 of file TrajectoryIterator.cpp.

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.

Definition at line 94 of file TrajectoryIterator.cpp.

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

(

const TrajectoryIterator &

rhs

)

Operator !=.

te::st::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.

Definition at line 84 of file TrajectoryIterator.cpp.

te::st::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.

Definition at line 58 of file TrajectoryIterator.cpp.

te::st::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.

Definition at line 64 of file TrajectoryIterator.cpp.

te::st::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.

Definition at line 71 of file TrajectoryIterator.cpp.

te::st::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.

Definition at line 77 of file TrajectoryIterator.cpp.

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

(

const TrajectoryIterator &

rhs

)

Assignment operator.

Definition at line 39 of file TrajectoryIterator.cpp.

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

(

const TrajectoryIterator &

rhs

)

Operator ==.
