  +--ru.sscc.spline.BaseSpline

Direct Known Subclasses:

Spline, Splines

public class BaseSpline

extends java.lang.Object

implements java.io.Serializable, java.lang.Cloneable

The parent class for all splines. It consists of 3 parts: a spline body is a constant part of spline shared by another splines and never modified on spline's life cycle; a spline data is a spline coefficients vector (nonmodified and nonshared); a spline workspace is a spline working area (contains only nonshared temporary information needed for spline value calculation).

A spline body.

Constructor Detail

BaseSpline

protected BaseSpline(SplineBody body,
                     RealContainer data)

Constructor.

Parameters:

body - a spline body

data - a spline coefficients container

Method Detail

dimension

public final int dimension()

Return a spline dimension (a number of independent variables).

flush

public final void flush()

Deletes workspace.

getBody

public final SplineBody getBody()

Returns the spline body.

getContainer

public final RealContainer getContainer()

Returns the spline coefficients container.

clone

public java.lang.Object clone()

Clones the spline.

Overrides:

clone in class java.lang.Object

Returns:

clone of this spline

prepareWorkspace

protected void prepareWorkspace(double point,
                                int index,
                                int count)

Prepares the workspace for an 1D spline derivative calculation at a point required. May be used for 1D splines only. A point is a point on the real axis and an index is a derivative index to be calculated. index=0 means a spline value calculation. A count parameter is an information on how many spline values will be later calculated for these parameters.

Parameters:

point - a point on the real axis

index - a derivative index

count - a number of splines will be calculated later

prepareWorkspace

protected void prepareWorkspace(RealPointer point,
                                int count)

Prepares the workspace for a spline calculation at a point required. May be used for any (1D or multi-D) splines. A point vector means a point in the space of independent variables where a calculation should be processed. A count parameter is an information on how many spline values will be later calculated for these parameters.

Parameters:

point - a point in the space of independent variables

count - a number of splines will be calculated later
