History:

2008-08-18 Christopher Austin - Upgraded to geos3.0.0, removed Chip.h include, fixed ifndef

2009-08-05 Travis Addair - Encapsulated group creation for seed definition group

2009-04-15 Eric Hyer - Now stores invalid input. Added Copy constructor, destructor, and assignment operator

2010-04-20 Christopher Austin - adapted for generic/unitless seeding

2012-04-17 Jeannie Backer - Added forward declaration for PvlObject and ordered includes in the implementation file. Added documentation. Moved Algorithm method from header file to implementation file.

Constructor & Destructor Documentation

◆ PolygonSeeder() [1/2]

Isis::PolygonSeeder::PolygonSeeder ( Pvl & pvl )

Create PolygonSeeder object.

Because this is a pure virtual class you can not create an PolygonSeeder class directly. Instead, see the PolygonSeederFactory class.

Parameters

pvl	A pvl object containing a valid PolygonSeeder specification

Definition at line 24 of file PolygonSeeder.cpp.

References invalidInput, p_algorithmName, and Parse().

◆ PolygonSeeder() [2/2]

Isis::PolygonSeeder::PolygonSeeder ( const PolygonSeeder & other )

Copy constructor.

Create PolygonSeeder object by copying the algorithm name, the minimum thickness, and the minimum area of an existing PolygonSeeder object.

Parameters

other The other PolygonSeeder object that will be copied.

Definition at line 43 of file PolygonSeeder.cpp.

References p_algorithmName, p_minimumArea, and p_minimumThickness.

◆ ~PolygonSeeder()

Isis::PolygonSeeder::~PolygonSeeder ( )

virtual

Destroys the PolygonSeeder object.

Definition at line 53 of file PolygonSeeder.cpp.

References invalidInput.

Member Function Documentation

◆ Algorithm()

QString Isis::PolygonSeeder::Algorithm ( ) const

The name of the algorithm, read from the Name Keyword in the PolygonSeeder Pvl passed into the constructor.

Returns: QString The value of the Name Keyword in the Pvl.

Definition at line 166 of file PolygonSeeder.cpp.

References p_algorithmName.

Referenced by Isis::LimitPolygonSeeder::PluginParameters(), Isis::StripPolygonSeeder::PluginParameters(), and Isis::GridPolygonSeeder::PluginParameters().

◆ InvalidInput()

Pvl Isis::PolygonSeeder::InvalidInput ( )

This method returns a copy of the Pvl passed in by the constructor (from a def file probably) minus what was used.

Returns: Pvl A copy of this pvl minus what was used.

Definition at line 225 of file PolygonSeeder.cpp.

References invalidInput.

◆ MinimumArea()

double Isis::PolygonSeeder::MinimumArea ( )

Return the minimum allowed area of the polygon.

This value is set from the "MinimumArea" keyword in the PVL. The seeding algorithm will not seed polygons that have an area less than this.

Returns: double The value for the minimum area allowed.

Definition at line 189 of file PolygonSeeder.cpp.

References p_minimumArea.

Referenced by Isis::LimitPolygonSeeder::PluginParameters(), Isis::StripPolygonSeeder::PluginParameters(), Isis::GridPolygonSeeder::PluginParameters(), and StandardTests().

◆ MinimumThickness()

double Isis::PolygonSeeder::MinimumThickness ( )

Return the minimum allowed thickness of the polygon.

This value is set from the "MinimumThickness" keyword in the PVL. The seeding algorithm will not seed polygons that have a thickness ratio less than this

Returns: double The value for the minimum thickness allowed.

Definition at line 177 of file PolygonSeeder.cpp.

References p_minimumThickness.

Referenced by Isis::LimitPolygonSeeder::PluginParameters(), Isis::StripPolygonSeeder::PluginParameters(), Isis::GridPolygonSeeder::PluginParameters(), Isis::GridPolygonSeeder::SeedSubGrid(), and StandardTests().

◆ operator=()

const PolygonSeeder & Isis::PolygonSeeder::operator= ( const PolygonSeeder & other )

Assignment operator.

Sets this PolygonSeeder object equal to another by copying the algorithm name, the minimum thickness, and the minimum area of the other PolygonSeeder object.

Parameters

other The other PolygonSeeder object whose values will be copied.

Returns: PolygonSeeder This PolygonSeeder object, once the other object's values have been copied.

Definition at line 240 of file PolygonSeeder.cpp.

References p_algorithmName, p_minimumArea, and p_minimumThickness.

◆ Parse()

void Isis::PolygonSeeder::Parse ( Pvl & pvl )

protectedvirtual

Initialize parameters in the PolygonSeeder class using a PVL specification.

An example of the PVL required for this is:

Object = AutoSeed
  Group = Algorithm
    Name      = Grid
    Tolerance = 0.7
  EndGroup
EndObject

There are many other options that can be set via the pvl and are described in other documentation (see below).

Parameters

pvl	The pvl object containing the specification

Reimplemented in Isis::GridPolygonSeeder, Isis::StripPolygonSeeder, and Isis::LimitPolygonSeeder.

◆ PluginParameters()

PvlGroup Isis::PolygonSeeder::PluginParameters ( QString grpName )

virtual

Plugin parameters.

This method will add the PvlKeyword values for algorithm name, minimum thickness, and minimum area of this object to a PvlGroup with the name that is passed in.

Parameters

grpName A string containing the PvlGroup name.

Returns: PvlGroup The PvlGroup with the appropriate parameters added.

Reimplemented in Isis::GridPolygonSeeder, Isis::StripPolygonSeeder, and Isis::LimitPolygonSeeder.

◆ Seed()

virtual std::vector<geos::geom::Point *> Isis::PolygonSeeder::Seed ( const geos::geom::MultiPolygon * mp )

pure virtual

Pure virtual seed method.

Parameters

mp	The MultiPolygon object from the geos::geom library.

Returns: std::vector<geos::geom::Point*> A vector of Point objects from the geos::geom library.

Implemented in Isis::StripPolygonSeeder, Isis::GridPolygonSeeder, and Isis::LimitPolygonSeeder.

◆ StandardTests()

QString Isis::PolygonSeeder::StandardTests	(	const geos::geom::MultiPolygon *	xymp,
		const geos::geom::Envelope *	xyBoundBox
	)

protected

Check the polygon to see if it meets standard criteria.

Parameters

xymp	The multipoly containing the coordinates in x/y units instead of lon/lat
xyBoundBox	The bounding box of the multipoly

Returns: QString A string with an appropriate message to throw if a test was unsuccessful or an empty string if all tests passed.
