Detailed Description

Base configuration for geometry checks.

Note: This class is a technology preview and unstable API.

Since: QGIS 3.4

Definition at line 31 of file qgsgeometrycheckcontext.h.

Constructor & Destructor Documentation

◆ QgsGeometryCheckContext()

QgsGeometryCheckContext::QgsGeometryCheckContext	(	int	precision,
		const QgsCoordinateReferenceSystem &	mapCrs,
		const QgsCoordinateTransformContext &	transformContext,
		const QgsProject *	mProject
	)

Creates a new QgsGeometryCheckContext.

Definition at line 19 of file qgsgeometrycheckcontext.cpp.

Member Function Documentation

◆ project()

const QgsProject * QgsGeometryCheckContext::project ( ) const

The project can be used to resolve additional layers.

This must only be accessed from the main thread (i.e. do not access from the collectError method)

Since: QGIS 3.10

Definition at line 28 of file qgsgeometrycheckcontext.cpp.

Member Data Documentation

◆ mapCrs

const QgsCoordinateReferenceSystem QgsGeometryCheckContext::mapCrs

The coordinate system in which calculations should be done.

Definition at line 61 of file qgsgeometrycheckcontext.h.

◆ reducedTolerance

const double QgsGeometryCheckContext::reducedTolerance

The tolerance to allow for in geometry checks.

Will be calculated as pow(10, -precision/2) in the constructor. I.e. if the precision is 4 (decimal digits), this will be 0.01. Should be used for areas, where the precision is squared.

Definition at line 56 of file qgsgeometrycheckcontext.h.

◆ tolerance

const double QgsGeometryCheckContext::tolerance

The tolerance to allow for in geometry checks.

Will be calculated as pow(10, -precision) in the constructor. I.e. if the precision is 4 (decimal digits), this will be 0.0001.

Definition at line 48 of file qgsgeometrycheckcontext.h.

◆ transformContext

const QgsCoordinateTransformContext QgsGeometryCheckContext::transformContext

The coordinate transform context with which transformations will be done.

Definition at line 66 of file qgsgeometrycheckcontext.h.
