Constructor Detail

FieldMap3D

public FieldMap3D(org.jdom.Element node)
           throws org.jdom.JDOMException

Throws:

org.jdom.JDOMException

Method Detail

setup

private void setup(String filename)
            throws IOException

Throws:

IOException

getField

public void getField(double[] position,
            double[] b)

Description copied from interface: FieldMap

Get the field magnitude and direction at a particular point.

Specified by:

getField in interface FieldMap

Overrides:

getField in class AbstractFieldMap

Parameters:

position - The position at which the field is requested

b - The field (the object is passed by reference and set to the correct field)

getField

public Hep3Vector getField(Hep3Vector position)

Description copied from interface: FieldMap

Get the field magnitude and direction at a particular point. Equivalent to getField(position,null).

Specified by:

getField in interface FieldMap

Overrides:

getField in class AbstractFieldMap

getField

public double[] getField(double[] position)

Description copied from interface: FieldMap

Get the field magnitude and direction at a particular point. This method requires allocation of a new object on each call, and should therefore not be used if it may be called many times.

Specified by:

getField in interface FieldMap

Overrides:

getField in class AbstractFieldMap

Parameters:

position - The position at which the field is requested

Returns:

The field.

getField

void getField(double x,
            double y,
            double z,
            BasicHep3Vector field)

Specified by:

getField in class AbstractFieldMap

globalOffset

public double[] globalOffset()

getField

private void getField(double x,
            double y,
            double z)

modf

private double[] modf(double fullDouble)
