Detailed Description

One part of a geometry: a polygon (exterior + holes), a line run, or a single point.

For non-polygon types holes is always empty and exterior carries the vertices (one for a point).

Member Function Documentation

boundingRect()

QRectF openswmmvis::feature::Part::boundingRect

(

)

const

Here is the call graph for this function:

containsPoint()

bool openswmmvis::feature::Part::containsPoint

(

const QPointF &

p

)

const

True when p is inside the exterior and outside every hole — the same predicate mesh::pointInRegion applies to quad regions.

Here is the call graph for this function:

isEmpty()

bool openswmmvis::feature::Part::isEmpty ( ) const

inline

Here is the call graph for this function:

netArea()

double openswmmvis::feature::Part::netArea

(

)

const

Ring area minus the area of every hole; absolute value, so orientation does not matter to the caller. Zero for non-polygon parts.

Here is the call graph for this function:

normalizeOrientation()

void openswmmvis::feature::Part::normalizeOrientation

(

)

Apply Ring::normalizeCCW to the exterior and reverse every hole so holes run clockwise — the OGR/GeoPackage convention.

Here is the call graph for this function:

operator!=()

bool openswmmvis::feature::Part::operator!= ( const Part &  o ) const

inline

operator==()

bool openswmmvis::feature::Part::operator==

(

const Part &

o

)

const
