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

◆ TrajectoryIterator() [1/2]

te::st::TrajectoryIterator::TrajectoryIterator ( )

Empty constructor.

◆ TrajectoryIterator() [2/2]

te::st::TrajectoryIterator::TrajectoryIterator ( TrajectoryObservationSet::const_iterator & it )

Constructor.

Parameters

it	A iterator that points to the trajectory observations

◆ ~TrajectoryIterator()

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

virtual

Virtual destructor.

Member Function Documentation

◆ getGeometry()

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.

◆ getTime()

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.

◆ operator!=()

bool te::st::TrajectoryIterator::operator!= ( const TrajectoryIterator & rhs )

Operator !=.

◆ 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.

◆ operator++() [1/2]

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.

◆ operator++() [2/2]

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.

◆ operator--() [1/2]

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.

◆ operator--() [2/2]

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.

◆ operator=()

const TrajectoryIterator& te::st::TrajectoryIterator::operator= ( const TrajectoryIterator & rhs )

Assignment operator.

◆ operator==()

bool te::st::TrajectoryIterator::operator== ( const TrajectoryIterator & rhs )

Operator ==.
