Detailed Description

The CombineGeometryDecorator class implements a decorator that combines two arbitrary geometries (with a relative weight factor) into an object that behaves as a single geometry.

Constructor & Destructor Documentation

CombineGeometryDecorator()

CombineGeometryDecorator::CombineGeometryDecorator ( )

inlineprotected

Default constructor for concrete Item subclass CombineGeometryDecorator : "a decorator that combines two different geometries" .

Member Function Documentation

density()

double CombineGeometryDecorator::density ( Position  bfr ) const

overridevirtual

This function returns the density $\rho (\mathbf{r})$ at the position $\mathbf{r}$. It adds the contribution of the two components, weighted by their weights.

Implements Geometry.

dimension()

int CombineGeometryDecorator::dimension ( ) const

overridevirtual

This function returns the dimension of the combined geometry, which depends on the (lack of) symmetry in the geometries of its stellar components. A value of 1 means spherical symmetry, 2 means axial symmetry and 3 means none of these symmetries. The geometry with the least symmetry (i.e. the highest dimension) determines the result for the whole system.

Implements Geometry.

firstGeometry()

Geometry * CombineGeometryDecorator::firstGeometry ( ) const

inline

This function returns the value of the discoverable item property firstGeometry : "the first geometry" .

firstWeight()

CombineGeometryDecorator::firstWeight ( ) const

inline

This function returns the value of the discoverable double property firstWeight : "the weight of the first geometry" .

The minimum value for this property is "]0" .

The default value for this property is given by the conditional value expression "1" .

generatePosition()

Position CombineGeometryDecorator::generatePosition ( ) const

overridevirtual

This function generates a random position from the geometry, by drawing a random point from the three-dimensional probability density $p(\mathbf{r})\text{d}\mathbf{r}=\rho (\mathbf{r})\text{d}\mathbf{r}$. It first generates a random component, and subsequently generates a random position from this component by calling the corresponding generatePosition() function.

Implements Geometry.

secondGeometry()

Geometry * CombineGeometryDecorator::secondGeometry ( ) const

inline

This function returns the value of the discoverable item property secondGeometry : "the second geometry" .

secondWeight()

CombineGeometryDecorator::secondWeight ( ) const

inline

This function returns the value of the discoverable double property secondWeight : "the weight of the second geometry" .

The minimum value for this property is "]0" .

The default value for this property is given by the conditional value expression "1" .

setupSelfBefore()

void CombineGeometryDecorator::setupSelfBefore ( )

overrideprotectedvirtual

This function normalizes the relative weights of the two geometries.

Reimplemented from SimulationItem.

SigmaX()

double CombineGeometryDecorator::SigmaX ( ) const

overridevirtual

This function returns the X-axis surface density, i.e. the integration of the density along the entire X-axis,

$${\mathrm{\Sigma }}_X={\int }_{-\mathrm{\infty }}^{\mathrm{\infty }}\rho (x,0,0)\text{d}x.$$

It adds the contribution of the two components, weighted by their weights.

Implements Geometry.

SigmaY()

double CombineGeometryDecorator::SigmaY ( ) const

overridevirtual

This function returns the Y-axis surface density, i.e. the integration of the density along the entire Y-axis,

$${\mathrm{\Sigma }}_Y={\int }_{-\mathrm{\infty }}^{\mathrm{\infty }}\rho (0,y,0)\text{d}y.$$

It adds the contribution of the two components, weighted by their weights.

Implements Geometry.

SigmaZ()

double CombineGeometryDecorator::SigmaZ ( ) const

overridevirtual

This function returns the Z-axis surface density, i.e. the integration of the density along the entire Z-axis,

$${\mathrm{\Sigma }}_Z={\int }_{-\mathrm{\infty }}^{\mathrm{\infty }}\rho (0,0,z)\text{d}z.$$

It adds the contribution of the two components, weighted by their weights.

Implements Geometry.
