Member Function Documentation

Geometry * MultiGeometry::cloneAs

(

const Geometry::Type &

newType

)

const [virtual]

Converts this geometry to another type. This function will return "this" if the type is the same, and will return NULL if the conversion is impossible.

Reimplemented from osgEarth::Symbology::Geometry.

Definition at line 635 of file Geometry.cpp.

{
    MultiGeometry* multi = new MultiGeometry();
    for( GeometryCollection::const_iterator i = _parts.begin(); i != _parts.end(); ++i )
    {
        Geometry* part = i->get()->cloneAs( i->get()->getType() );
        if ( part ) multi->getComponents().push_back( part );
    }
    return multi;
}

Here is the call graph for this function:

Bounds MultiGeometry::getBounds

(

)

const [virtual]

Gets the bounds of this geometry

Reimplemented from osgEarth::Symbology::Geometry.

Definition at line 624 of file Geometry.cpp.

{
    Bounds bounds;
    for( GeometryCollection::const_iterator i = _parts.begin(); i != _parts.end(); ++i )
    {
        bounds.expandBy( i->get()->getBounds() );
    }
    return bounds;
}

Here is the call graph for this function:

GeometryCollection& osgEarth::Symbology::MultiGeometry::getComponents

(

)

[inline]

Definition at line 312 of file Geometry.

{ return _parts; }

Here is the caller graph for this function:

const GeometryCollection& osgEarth::Symbology::MultiGeometry::getComponents

(

)

const [inline]

Definition at line 313 of file Geometry.

{ return _parts; }

Geometry::Type MultiGeometry::getComponentType

(

)

const [virtual]

Reimplemented from osgEarth::Symbology::Geometry.

Definition at line 599 of file Geometry.cpp.

{
    // dicey.
    return _parts.size() > 0 ? _parts.front()->getType() : TYPE_UNKNOWN;
}

virtual unsigned osgEarth::Symbology::MultiGeometry::getNumComponents

(

)

const [inline, virtual]

Gets the total number of geometry components

Reimplemented from osgEarth::Symbology::Geometry.

Definition at line 302 of file Geometry.

{ return _parts.size(); }

unsigned MultiGeometry::getNumGeometries

(

)

const [virtual]

Gets the total number of geometries; it is the total of all parts of all components. Also can be seen as the number of Geometry objects that would be returned by a full GeometryIterator.

Reimplemented from osgEarth::Symbology::Geometry.

Definition at line 615 of file Geometry.cpp.

{
    unsigned total = 0;
    for( GeometryCollection::const_iterator i = _parts.begin(); i != _parts.end(); ++i )
        total += i->get()->getNumGeometries();
    return total;
}

int MultiGeometry::getTotalPointCount

(

)

const [virtual]

Gets the total number of points in this geometry.

Reimplemented from osgEarth::Symbology::Geometry.

Definition at line 606 of file Geometry.cpp.

{
    int total = 0;
    for( GeometryCollection::const_iterator i = _parts.begin(); i != _parts.end(); ++i )
        total += i->get()->getTotalPointCount();
    return total;
}

virtual Type osgEarth::Symbology::MultiGeometry::getType

(

)

const [inline, virtual]

Implements osgEarth::Symbology::Geometry.

Definition at line 299 of file Geometry.

{ return Geometry::TYPE_MULTI; }        

bool MultiGeometry::isValid

(

)

const [virtual]

Reimplemented from osgEarth::Symbology::Geometry.

Definition at line 647 of file Geometry.cpp.

{
    if ( _parts.size() == 0 )
        return false;

    bool valid = true;
    for( GeometryCollection::const_iterator i = _parts.begin(); i != _parts.end() && valid; ++i )
    {
        if ( !i->get()->isValid() )
            valid = false;
    }
    return valid;
