Method Detail

attachSplineBody

protected void attachSplineBody(SplineBody body)

Attaches a spline body to the creator and sets the prepared tag to false.

Parameters:

body - a spline body to attach

clone

public java.lang.Object clone()

Should return nonprepared clone of the creator.

Overrides:

clone in class java.lang.Object

getSplineBody

public final SplineBody getSplineBody()

Returns the spline body.

sourceSize

public abstract int sourceSize()

Returns a size of an interpolating data vector.

targetSize

public final int targetSize()

Returns a size of a spline coefficients vector.

setPrepared

protected final void setPrepared(boolean prepared)

Sets the value of prepared tag.

isPrepared

public final boolean isPrepared()

Returns true if the creator is prepared.

ensurePrepared

public final void ensurePrepared()

Ensures the creator prepared. If not, the IllegalStateException is thrown.

calculate

public abstract void calculate(RealVector source,
                               RealVector target)

public final Splines constructSplinesByRows(RealVectors source)

Constructs a spline vector via its interpolating data coefficients represented by rows of a RealVectors array.

Parameters:

source - an array of interpolated vectors

Returns:

the spline vector
