Constructor & Destructor Documentation

PolylineChange()

luciad::PolylineChange::PolylineChange

(

)

Constructs an empty polyline change.

Member Function Documentation

addInsertedPoint()

void luciad::PolylineChange::addInsertedPoint

(

size_t

insertedPointIndex

)

Adds the index of the point that is inserted.

Parameters

insertedPointIndex

the index of the point in the new polyline that was inserted in this change.

See also

getInsertedPoints

addMovedPoint()

void luciad::PolylineChange::addMovedPoint

(

size_t

movedPointIndex

)

Adds the index of the point that is moved.

Parameters

movedPointIndex

the index of the point in the new polyline that was moved in this change.

See also

getMovedPoints

addRemovedPoint()

void luciad::PolylineChange::addRemovedPoint

(

size_t

removedPointIndex

)

Adds the index of the point that is removed.

Parameters

removedPointIndex

the index of the point in the old polyline that was removed in this change.

See also

getRemovedPoints

getInsertedPoints()

const std::vector< size_t > & luciad::PolylineChange::getInsertedPoints

(

)

const

Returns the indices of the points in the new polyline that were inserted in this change.

Returns

the indices of the points in the new polyline that were inserted in this change.

getMovedPoints()

const std::vector< size_t > & luciad::PolylineChange::getMovedPoints

(

)

const

Returns the indices of the points in the new polyline that were moved in this change.

This only considers individual point moves, so if the whole polyline was translated, this method can still return false for individual points. For checking whether a translation took place, see getTranslation.

Returns

the indices of the points in the new polyline that were moved in this change.

getRemovedPoints()

const std::vector< size_t > & luciad::PolylineChange::getRemovedPoints

(

)

const

Returns the indices of the points in the old polyline that were removed in this change.

Returns

the indices of the points in the old polyline that were removed in this change.

getTranslation()

std::optional< Coordinate > luciad::PolylineChange::getTranslation

(

)

const

Returns the translation that was applied on the polyline.

This is the result of use the method translate on the polyline. The value may be std::nullopt if no translation happened.

Returns

the translation that was applied on the polyline.

hasPointInserted()

bool luciad::PolylineChange::hasPointInserted

(

size_t

index

)

const

Returns true if the inserted points of this change contain the given index.

Parameters

index

the point index in the new polyline.

Returns

true if the inserted points of this change contain the given index.

hasPointMoved()

bool luciad::PolylineChange::hasPointMoved

(

size_t

index

)

const

Returns true if the moved points of this change contain the given index.

Parameters

index

the point index in the new polyline.

Returns

true if the moved points of this change contain the given index.

hasPointRemoved()

bool luciad::PolylineChange::hasPointRemoved

(

size_t

index

)

const

Returns true if the removed points of this change contain the given index.

Parameters

index

the point index in the old polyline.

Returns

true if the removed points of this change contain the given index.

setTranslation()

void luciad::PolylineChange::setTranslation

(

Coordinate

translation

)

Sets the translation that was applied on the polyline.

Parameters

translation

the translation that was applied on the polyline in this change.
