Detailed Description

Handle conversion of data buffers described by an IOLink DataType.

Member Function Documentation

convert()

static void iolink::DataConverter::convert ( DataType  srcType, const void *  src, DataType  dstType, void *  dst, size_t  count  )

static

Convert each element of the source buffer into another data type and writes it into the destination buffer.

This method uses the simpliest way of converting data: static casting. So it is only compatible with numeric types, and can lead to stranges values in specific cases.

This method throws an exception when the arguments are invalid (null buffers for example), when types aren't numeric ones, or when the source type is not convertible into the destination one.

DataType::isConvertibleTo

Parameters

srcType	The type of data stored in the source buffer
src	The source buffer
dstType	The type of data stored in the destination buffer
dst	The destination buffer
count	The number of element to convert

Exceptions

Error

endianReverse()

static void iolink::DataConverter::endianReverse ( DataType  srcType, const void *  src, void *  dst, size_t  count  )

static

This converter is used to revert endianness of a set of samples.

This method throws an exception when the arguments are invalid (null buffers for example), when given source type is not handled.

Parameters

srcType	The type of data stored in the source buffer
src	The source buffer
dst	The destination buffer
count	The number of element to convert

Exceptions

Error

if given datatype is not handled
