Method Details

isZeroField

public final boolean isZeroField()

Checks whether the field has been set to always return zero.

Specified by:

isZeroField in interface IMagField

Overrides:

isZeroField in class MagneticField

Returns:

true if the field is set to return zero.

isActive

public boolean isActive()

Checks this field active.

Specified by:

isActive in class MagneticField

Returns:

true if this field is active;

isSolenoidAdded

public boolean isSolenoidAdded()

Has part of the solenoid been added in to remove the overlap?

Returns:

true if the solenoid was added in.

fromBinaryFile

public static Torus fromBinaryFile(File file)
                            throws FileNotFoundException

Obtain a torus object from a binary file, probably "clas12-fieldmap-torus.dat"

Parameters:

file - the file to read

Returns:

the torus object

Throws:

FileNotFoundException - the file not found exception

getPhiMax

public double getPhiMax()

Get the maximum phi coordinate of the field boundary (deg)

Returns:

the maximum phi coordinate of the field boundary

getPhiMin

public double getPhiMin()

Get the minimum phi coordinate of the field boundary (deg)

Returns:

the minimum phi coordinate of the field boundary

getName

public String getName()

Get the name of the field

Returns:

the name

isFullMap

public boolean isFullMap()

Check whether there is an assume 12-fold symmetry

Returns:

true if this is a full map

toString

public final String toString()

Get some data as a string.

Overrides:

toString in class MagneticField

Returns:

a string representation.

addToField

public void addToField(int compositeIndex,

Used to add the solenoid into the torus. Experimental!!

Parameters:

compositeIndex - the composite index

result - the solenoid field added in

printConfiguration

public void printConfiguration(PrintStream ps)

Print the current configuration

Parameters:

ps - the print stream
