  org.deegree.model.csct.ct.AbstractMathTransform
      org.deegree.model.csct.ct.ConcatenedTransform
          org.deegree.model.csct.ct.ConcatenedTransformDirect

All Implemented Interfaces:

Serializable, MathTransform

Direct Known Subclasses:

ConcatenedTransformDirect2D

 class ConcatenedTransformDirect
extends ConcatenedTransform

Concatened transform where the transfert dimension is the same than source and target dimension. This fact allows some optimizations, the most important one being the possibility to avoid the use of an intermediate buffer.

Constructor Detail

ConcatenedTransformDirect

public ConcatenedTransformDirect(MathTransformFactory provider,
                                 MathTransform transform1,
                                 MathTransform transform2)

Construct a concatenated transform.

Method Detail

isValid

protected boolean isValid()

Check if transforms are compatibles with this implementation.

Overrides:

isValid in class ConcatenedTransform

transform

public CoordinatePoint transform(CoordinatePoint ptSrc,
                                 CoordinatePoint ptDst)
                          throws TransformException

Transforms the specified ptSrc and stores the result in ptDst.

Specified by:

transform in interface MathTransform

Overrides:

transform in class ConcatenedTransform

Parameters:

ptSrc - the specified coordinate point to be transformed.

ptDst - the specified coordinate point that stores the result of transforming ptSrc, or null.

Returns:

the coordinate point after transforming ptSrc and storing the result in ptDst, or a newly created point if ptDst was null.

Throws:

TransformException - if the point can't be transformed.

transform

public void transform(double[] srcPts,
                      int srcOff,
                      double[] dstPts,
                      int dstOff,
                      int numPts)
               throws TransformException

Transforms a list of coordinate point ordinal values.

Specified by:

transform in interface MathTransform

Overrides:

transform in class ConcatenedTransform

Parameters:

srcPts - the array containing the source point coordinates.

srcOff - the offset to the first point to be transformed in the source array.

dstPts - the array into which the transformed point coordinates are returned. May be the same than srcPts.

dstOff - the offset to the location of the first transformed point that is stored in the destination array.

numPts - the number of point objects to be transformed.

Throws:

TransformException - if a point can't be transformed.

transform

public void transform(float[] srcPts,
                      int srcOff,
                      float[] dstPts,
                      int dstOff,
                      int numPts)
               throws TransformException

Transforms a list of coordinate point ordinal values.

Specified by:

transform in interface MathTransform

Overrides:

transform in class ConcatenedTransform

Parameters:

srcPts - the array containing the source point coordinates.

srcOff - the offset to the first point to be transformed in the source array.

dstPts - the array into which the transformed point coordinates are returned. May be the same than srcPts.

dstOff - the offset to the location of the first transformed point that is stored in the destination array.

numPts - the number of point objects to be transformed.

Throws:

TransformException - if a point can't be transformed.
