DataBufferwhose data type, number of banks and size are consistent with thisComponentSampleModel. - Throws:

getDataElements
Returns data for a single pixel in a primitive array of type TransferType. For a BandedSampleModel, this will be the same as the data type, and samples will be returned one per array element. Generally, obj should be passed in as null, so that the Object will be created automatically and will be of the right primitive data type.The following code illustrates transferring data for one pixel from DataBuffer
db1, whose storage layout is described by BandedSampleModelbsm1, to DataBufferdb2, whose storage layout is described by BandedSampleModelbsm2. The transfer will generally be more efficient than using getPixel/setPixel.BandedSampleModel bsm1, bsm2; DataBufferInt db1, db2; bsm2.setDataElements(x, y, bsm1.getDataElements(x, y, null, db1), db2);Using getDataElements/setDataElements to transfer between two DataBuffer/SampleModel pairs is legitimate if the SampleModels have the same number of bands, corresponding bands have the same number of bits per sample, and the TransferTypes are the same.If obj is non-null, it should be a primitive array of type TransferType. Otherwise, a ClassCastException is thrown. An ArrayIndexOutOfBoundsException may be thrown if the coordinates are not in bounds, or if obj is non-null and is not large enough to hold the pixel data.
