Enum Constant Details

X

public static final PhaseMatrix.IND X

Index of the x coordinate

XP

public static final PhaseMatrix.IND XP

Index of the X' coordinate

Y

public static final PhaseMatrix.IND Y

Index of the Y coordinate

YP

public static final PhaseMatrix.IND YP

Index of the Y' coordinate

Z

public static final PhaseMatrix.IND Z

Index of the Z (longitudinal) coordinate

ZP

public static final PhaseMatrix.IND ZP

Index of the Z' (change in momentum) coordinate

HOM

Method Details

values

public static PhaseMatrix.IND[] values()

Returns an array containing the constants of this enum class, in the order they are declared.

Returns:

an array containing the constants of this enum class, in the order they are declared

valueOf

public static PhaseMatrix.IND valueOf(String name)

Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum class has no constant with the specified name

NullPointerException - if the argument is null

valuesPhase

public static Set<PhaseMatrix.IND> valuesPhase()

Returns the set of index constants that correspond to phase coordinates only. The homogeneous coordinate index is not included (i.e., the IND.HOM constant).

Returns:

the set of phase indices IND less the HOM constant
