Detailed Description

A complete feature geometry: a type plus zero or more parts.

Single-part types (Point, LineString, Polygon) hold exactly one entry in parts; the accessors tolerate more and use the first. Multi* types hold any number.

Member Function Documentation

addPart()

void openswmmvis::feature::FeatureGeometry::addPart ( const Part &  p )

inline

Here is the caller graph for this function:

area()

double openswmmvis::feature::FeatureGeometry::area

(

)

const

Sum of Part::netArea over every part.

boundingRect()

QRectF openswmmvis::feature::FeatureGeometry::boundingRect

(

)

const

clear()

void openswmmvis::feature::FeatureGeometry::clear ( )

inline

densify()

int openswmmvis::feature::FeatureGeometry::densify

(

double

spacing

)

Ring::densify on every ring of every part; returns the number of vertices inserted in total.

Here is the caller graph for this function:

fromOGR()

FeatureGeometry openswmmvis::feature::FeatureGeometry::fromOGR ( const OGRGeometry *  g )

static

Build a FeatureGeometry from g.

Reads 2.5D coordinates when the source geometry carries them. Unsupported geometry classes (curves, geometry collections) yield a GeometryType::None result rather than throwing.

hasZ()

bool openswmmvis::feature::FeatureGeometry::hasZ

(

)

const

True when EVERY non-empty ring carries a well-formed Z array.

Here is the caller graph for this function:

isEmpty()

bool openswmmvis::feature::FeatureGeometry::isEmpty

(

)

const

Here is the caller graph for this function:

isValid()

bool openswmmvis::feature::FeatureGeometry::isValid ( ) const

inline

Here is the call graph for this function:

Here is the caller graph for this function:

length()

double openswmmvis::feature::FeatureGeometry::length

(

)

const

Sum of exterior-ring 2D lengths — meaningful for line types.

normalizeOrientation()

void openswmmvis::feature::FeatureGeometry::normalizeOrientation

(

)

Here is the caller graph for this function:

ogrTypeFor()

int openswmmvis::feature::FeatureGeometry::ogrTypeFor ( GeometryType  t, bool  withZ  )

static

The OGR well-known-binary type constant for t, with the 25D flag set when withZ. Used when creating the GeoPackage table.

operator!=()

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

inline

operator==()

bool openswmmvis::feature::FeatureGeometry::operator==

(

const FeatureGeometry &

o

)

const

partCount()

int openswmmvis::feature::FeatureGeometry::partCount ( ) const

inline

parts() [1/2]

QVector< Part > & openswmmvis::feature::FeatureGeometry::parts ( )

inline

parts() [2/2]

const QVector< Part > & openswmmvis::feature::FeatureGeometry::parts ( ) const

inline

Here is the caller graph for this function:

setHasZ()

void openswmmvis::feature::FeatureGeometry::setHasZ

(

bool

on

)

Give (or drop) Z arrays on every ring to match on.

Here is the caller graph for this function:

setType()

void openswmmvis::feature::FeatureGeometry::setType ( GeometryType  t )

inline

Here is the caller graph for this function:

toOGR()

OGRGeometry * openswmmvis::feature::FeatureGeometry::toOGR

(

OGRSpatialReference *

srs = nullptr

)

const

Build a new OGR geometry. The CALLER OWNS the result and must release it with OGRGeometryFactory::destroyGeometry.

Parameters

srs	Optional; assigned to the geometry when non-null.

Returns

nullptr when this geometry is empty or of type None.

Here is the call graph for this function:

Here is the caller graph for this function:

type()

GeometryType openswmmvis::feature::FeatureGeometry::type ( ) const

inline

unsampledZCount()

int openswmmvis::feature::FeatureGeometry::unsampledZCount

(

)

const

Count of vertices whose Z is NaN, across all 3D rings. Reported in the Features dock so an un-sampled breakline is visible rather than silent.

validate()

bool openswmmvis::feature::FeatureGeometry::validate	(	GeometryType	expected,
		QString *	reason = nullptr
	)		const

Structural check against expected.

Parameters

expected	The layer's declared type.
reason	Set to a user-facing message when the result is false.

Rejects: wrong part count for a single-part type, empty rings, polygons with fewer than three vertices, self-intersecting rings, holes not contained by their exterior, and holes that overlap one another. These are the same rules QUAD_MESHING_REDESIGN_PLAN §5 states for a drawn quad region, so a polygon that passes here is admissible as a region ring.

Here is the call graph for this function:

Here is the caller graph for this function:

vertexCount()

int openswmmvis::feature::FeatureGeometry::vertexCount

(

)

const

Total vertex count across every ring of every part.

zRange()

bool openswmmvis::feature::FeatureGeometry::zRange	(	double &	minZ,
		double &	maxZ
	)		const

Min / max of the finite Z values. Returns false when there are none.
