org.apache.sis.io.wkt.FormattableObject

org.apache.sis.referencing.operation.transform.AbstractMathTransform

org.apache.sis.referencing.operation.transform.ConcatenatedTransform

org.apache.sis.referencing.operation.transform.ConcatenatedTransformDirect

All Implemented Interfaces:

Serializable, Parameterized, LenientComparable, org.opengis.referencing.operation.MathTransform

Direct Known Subclasses:

ConcatenatedTransformDirect1D, ConcatenatedTransformDirect2D

class ConcatenatedTransformDirect
extends ConcatenatedTransform

Concatenated transform where the transfer 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 in some case.

ConcatenatedTransformDirect

ConcatenatedTransformDirect(org.opengis.referencing.operation.MathTransform transform1,
 org.opengis.referencing.operation.MathTransform transform2)

Constructs a concatenated transform.

Method Details

isValid

boolean isValid()

Checks if transforms are compatibles with this implementation.

Overrides:

isValid in class ConcatenatedTransform

transform

public org.opengis.geometry.DirectPosition transform(org.opengis.geometry.DirectPosition ptSrc,
 org.opengis.geometry.DirectPosition ptDst)
                                              throws org.opengis.referencing.operation.TransformException

Transforms the specified ptSrc and stores the result in ptDst.

Specified by:

transform in interface org.opengis.referencing.operation.MathTransform

Overrides:

transform in class ConcatenatedTransform

Parameters:

ptSrc - the coordinate tuple to be transformed.

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

Returns:

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

Throws:

org.opengis.referencing.operation.TransformException - if ConcatenatedTransform.transform1 or ConcatenatedTransform.transform2 failed.

transform

public void transform(double[] srcPts,
 int srcOff,
 double[] dstPts,
 int dstOff,
 int numPts)
               throws org.opengis.referencing.operation.TransformException

Transforms many positions in a list of coordinate values.

Specified by:

transform in interface org.opengis.referencing.operation.MathTransform

Overrides:

transform in class ConcatenatedTransform

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:

org.opengis.referencing.operation.TransformException - if ConcatenatedTransform.transform1 or ConcatenatedTransform.transform2 failed.

public void transform(float[] srcPts,
 int srcOff,
 double[] dstPts,
 int dstOff,
 int numPts)
               throws org.opengis.referencing.operation.TransformException

Transforms many positions in a list of coordinate values.

Specified by:

transform in interface org.opengis.referencing.operation.MathTransform

Overrides:

transform in class ConcatenatedTransform

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.

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:

org.opengis.referencing.operation.TransformException - if ConcatenatedTransform.transform1 or ConcatenatedTransform.transform2 failed.
