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.

- 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 |

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 |
