Synopsis

This class consists of several static functions to convert data from local (=native) format to a canonical format. The canonical length of each data type is:
- Bool: 1 bit
- char: 1 byte
- short: 2 bytes
- int: 4 bytes
- Int64: 8 bytes
- float: 4 bytes
- double: 8 bytes
The canonical format is big-endian IEEE format, so on many machines the conversion is only a copy operation. On Alpha- or Intel-based machines, however, it involves a byte swap to convert from little endian to big endian.

The class also contains conversion functions making it possible to specify the number of bytes (in local format) instead of the number of values. These functions are included to make it possible to have the same signature as memcpy.

The current implementation of this class works on big- and little-endian machines using IEEE format. When using on other machines (e.g. VAX) the toLocal and fromLocal functions have to be changed.

Note that no functions are provided to handle Bools. Instead class Conversion provides functions to convert Bools to/from bits.

Example

    void someFunction (const uInt* data, uInt nrval)
    {
        char* buffer = new char[nrval*CanonicalConversion::canonicalSize(data)];
        CanonicalConversion::fromLocal (buffer, data, nrval);
        ...\.
        delete [] buffer;
    }

Motivation

AIPS++ data will be stored in a canonical format. To read these data conversion functions are needed. However, these functions do not use any other AIPS++ classes, so they can easily be used in any other software system.

To Do

• Support data type long double.

static void* casa::CanonicalConversion::byteFromLocalChar	(	void *	to,
		const void *	from,
		unsigned int	nrbytes
	)		[static]

Convert values from local format to canonical format.

The from and to buffer should not overlap. The number of values involved is determined from the argument nrbytes, which gives the number of bytes in local format. The signature of this function is the same as memcpy, so that memcpy can directly be used if no conversion is needed.
