GMModelInterfaces CATCGMTessPolyIter

Usage: you must use this class as is. You should never derive it.

public class CATCGMTessPolyIter

Class defining the iterator on the polygons resulting from a Tessellation operator.

Such iterator is directly created by the or methods. Its deletion is managed at the CATICGMBodyTessellator and CATICGMCellTessellator deletion.
Use it according to the following scheme:

If the polygon is closed, the first and last point of the polygon are different.

This class also allows you to directly retrieve the results in an array that you have to allocate and deallocate after use.

Method Index


o GetNbPoly(CATLONG32&)
Returns the number of polygons.
o GetPolyAllNuPts(int[],int[])
Globally retrieves the points ranks for all the polygons.
o GetPolyNbPts()
Returns the number of points of the current polygon.
o GetPolyNuPts(int[])

Constructor and Destructor


o ~CATCGMTessPolyIter
public virtual ~CATCGMTessPolyIter()
Destructor.

Methods


o GetNbPoly
public virtual GetNbPoly( ioNbPtsAll)
Returns the number of polygons.
Parameters:
ioNbPtsAll
The sum of the number of points for the definition of all the polygons.
Returns:
The number of polygons.
o GetPolyAllNuPts
public virtual GetPolyAllNuPts( oNbPts,
oNuPts)
Globally retrieves the points ranks for all the polygons.
Parameters:
ioNbPts[]
The array of the number of points for each polygon. The allocation has to be managed by the caller: use GetNbPoly for its dimension.
oNuPts[]
The array of the points ranks. The allocation has to be managed by the caller: use oNbPtsAll for its dimension.
o GetPolyNbPts
public virtual GetPolyNbPts()
Returns the number of points of the current polygon.
Returns:
The number of points.
o GetPolyNuPts
public virtual GetPolyNuPts( oNuPts)
Retrieves the points ranks (as int) defining the current polygon.
Parameters:
iNuPts[]
The array of the points ranks. The allocation has to be managed by the caller: use GetPolyNbPts for its dimension.
o GetPolyNuPts
public virtual GetPolyNuPts( iNuPts)
Retrieves the points ranks (as CATLONG32) defining the current polygon.
Parameters:
iNuPts[]
The array of the points ranks. The allocation has to be managed by the caller: use GetPolyNbPts for its dimension.
o GoToNext
public virtual GoToNext()
Skips to the next polygon.
o IsExhausted
public virtual IsExhausted()
Tests whether the list is completed.
Returns:
The result of the test.
Legal values: 1 if the list is completed, 0 otherwise.
o Reset
public virtual Reset()
Resets the iterator to the beginning.
