These routines are designed to be portable--they use the * C compiler to do the required native data manipulation. * 2. These routines copy the data at least once -- a serious * but unavoidable performance hit. */ #define TARGET jdouble #define TARGET_ARRAY jdoubleArray #define METHODNAMETB "copyDoubleToByte" #define FUNCTIONNAMETB Java_ch_systemsx_cisd_base_convert_NativeData_copyDoubleToByte___3DI_3BIII #define METHODNAMEBT "copyByteToDouble" #define FUNCTIONNAMEBT Java_ch_systemsx_cisd_base_convert_NativeData_copyByteToDouble___3BI_3DIII #define COPY_FUNC GetDoubleArrayRegion #define CHANGE_BYTE_ORDER CHANGE_BYTE_ORDER_8 #include "copyByteTarget.ctempl"
