Detailed Description

A class to traverse the observations of a PointCoverage.

This class provides a mechanism to traverse the point coverage observations sequentially.

An example of use:

PointCoverageIterator it = cv.begin(); while(it!=cv.end()) { Point& l = it.getLocation(); double v = it.getDouble(i); //or getValue() or getInt or... ++it; }

Member Function Documentation

double te::st::PointCoverageIterator::getDouble

(

int

i

)

const

It returns the i-th attribute value as a double pointed by the internal cursor.

Parameters

i	The index of the property to be returned.

Returns

The attribute value as a double pointed by the internal cursor.

double te::st::PointCoverageIterator::getDouble

(

)

const

It returns the first attribute value as a double pointed by the internal cursor.

Returns

The attribute value as a double pointed by the internal cursor.

int te::st::PointCoverageIterator::getInt

(

int

i

)

const

It returns the i-th attribute value as an integer pointed by the internal cursor.

Parameters

i	The index of the property to be returned.

Returns

The attribute value as an integer pointed by the internal cursor.

int te::st::PointCoverageIterator::getInt

(

)

const

It returns the first attribute value as an integer pointed by the internal cursor.

Returns

The first attribute value as an integer pointed by the internal cursor.

te::gm::Point& te::st::PointCoverageIterator::getLocation

(

)

const

It returns the location pointed by the internal cursor.

Returns

A reference to the location pointed by the internal cursor.

te::dt::AbstractData* te::st::PointCoverageIterator::getValue

(

int

i

)

const

It returns the i-th attribute value pointed by the internal cursor.

Parameters

i	The index of the property to be returned.

Returns

A pointer to the attribute value pointed by the internal cursor.

Note

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

te::dt::AbstractData* te::st::PointCoverageIterator::getValue

(

)

const

It returns the first attribute value pointed by the internal cursor.

Returns

A pointer to the first attribute value pointed by the internal cursor.

Note

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

bool te::st::PointCoverageIterator::operator!=

(

const PointCoverageIterator &

rhs

)

Operator !=.

PointCoverageObservation te::st::PointCoverageIterator::operator*

(

)

const

Prefix operator *.

It returns the item (a shared pointer to a pair of a point and a vector of values) pointed by the internal cursor.

PointCoverageIterator& te::st::PointCoverageIterator::operator++

(

)

Prefix operator ++.

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

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

PointCoverageIterator te::st::PointCoverageIterator::operator++

(

int

aux

)

Postfix operator ++.

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

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

PointCoverageIterator& te::st::PointCoverageIterator::operator--

(

)

Prefix operator –.

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

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

PointCoverageIterator te::st::PointCoverageIterator::operator--

(

int

aux

)

Postfix operator –.

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

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

const PointCoverageIterator& te::st::PointCoverageIterator::operator=

(

const PointCoverageIterator &

rhs

)

Assignment operator.

bool te::st::PointCoverageIterator::operator==

(

const PointCoverageIterator &

rhs

)

Operator ==.
