Constructor Detail

ChandrasekharsQuadrature

public ChandrasekharsQuadrature()

Constructs a ChandrasekharsQuadrature object with a default number of nodes, a LaguerreSolver with default precision and integration bounds set to [0,1].

Method Detail

integrate

public double integrate()

Description copied from class: AbstractIntegrator

Calculates the definite integral within the specified integration bounds.

Specified by:

integrate in class AbstractIntegrator

Returns:

the value of the integral

getQuadraturePoints

public NumericProperty getQuadraturePoints()

setQuadraturePoints

public void setQuadraturePoints(NumericProperty m)

set

public void set(NumericPropertyKeyword type,
                NumericProperty property)

Description copied from class: Accessible

An abstract method, which must be overriden to gain access over setting the values of all relevant (selected by the programmer) NumericProperties in subclasses of Accessible. Typically this involves a switch statement that goes through the different options for the type and invokes different set(...) methods to update the matching NumericProperty with property.

Specified by:

set in class Accessible

Parameters:

type - the type, which must be equal by definition to property.getType().

property - the property, which contains new information.

listedKeywords

public Set<NumericPropertyKeyword> listedKeywords()

Description copied from class: PropertyHolder

By default, this will search the children of this PropertyHolder to collect the types of their listed numeric parameters recursively.

Overrides:

listedKeywords in class PropertyHolder

Returns:

a set of NumericPropertyKeyword instances, which have been explicitly marked as a listed parameter for this PropertyHolder.

toString

public String toString()

Overrides:

toString in class Object
