Due to the current gap in continued funding from the U.S. National Science Foundation (NSF), the NSF Unidata Program Center has temporarily paused most operations. See NSF Unidata Pause in Most Operations for details.
Guys - oops... the method I sent in the original report was not quite right. This is what Ghansham and I believe the toFloatArray() method should look like. The further change is near the beginning, setting fromClass. Previously, the method was basing the originating class type on the destination class type, which we know is float! Previous two lines: Object dst = arr.get1DJavaArray(float.class); Class fromClass = dst.getClass().getComponentType(); /** * Get the 1D values for an array as floats. * * @param arr Array of values * @return float representation */ public static float[] toFloatArray(Array arr) { Class fromClass = arr.getElementType(); if (fromClass.equals(float.class)) { //It should always be a float return (float[]) dst; } else { float[] values = new float[(int) arr.getSize()]; boolean isUnsigned = arr.isUnsigned(); if (fromClass.equals(byte.class)) { byte[] fromArray = (byte[]) dst; for (int i = 0; i < fromArray.length; ++i) { if (isUnsigned) { values[i] = (int) fromArray[i] & 0xFF; } else { values[i] = fromArray[i]; } } } else if (fromClass.equals(short.class)) { short[] fromArray = (short[]) dst; for (int i = 0; i < fromArray.length; ++i) { if (isUnsigned) { values[i] = (int) fromArray[i] & 0xFFFF; } else { values[i] = fromArray[i]; } } } else if (fromClass.equals(int.class)) { int[] fromArray = (int[]) dst; for (int i = 0; i < fromArray.length; ++i) { if (isUnsigned) { values[i] = (long) fromArray[i] & 0xFFFFFFFF; } else { values[i] = fromArray[i]; } } } else if (fromClass.equals(double.class)) { double[] fromArray = (double[]) dst; for (int i = 0; i < fromArray.length; ++i) { values[i] = (float) fromArray[i]; } } else { throw new IllegalArgumentException("Unknown array type:" + fromClass.getName()); } return values; } } -- Tommy Jasmin Space Science and Engineering Center University of Wisconsin, Madison 1225 West Dayton Street, Madison, WI 53706
