arguments - Specifying custom type for an attribute of a UML class -

i have class attribute called interval , give attribute minimum , maximum value bound interval,

how can represent this? possible?

create value type - classifier «data type» stereotype - compound type, utilize type of attribute.

for example, says classa has public attribute called interval of type interval, , interval value type has public min , max attributes of type double:

+----------------+ +-----------------------+ | «data type» | | classa | | interval | +-----------------------+ +----------------+ | + interval : interval | | + min : double | +-----------------------+ | + max : double | +----------------+

as interval value type, identity not important, held value in classa , implemented struct (if target language supports values , structs; can't have value type in java illustration stereotype implemented convention, string in java have remember not utilize == on strings identities don't matter).

you can set «uses» dependency classa interval, implicit attribute's type mutual omit it.

Accessing MATLAB's unicode strings from C -

Accessing MATLAB's unicode strings from C - how can access underlying unicode info of matlab strings through matlab engine or mex c interfaces? here's example. let's set unicode characters in utf-8 encoded file test.txt, read as fid=fopen('test.txt','r','l','utf-8'); s=fscanf(fid, '%s') in matlab. now if first feature('defaultcharacterset', 'utf-8') , c engevalstring(ep, "s") , output text file utf-8. proves matlab stores unicode internally. if mxarraytostring(enggetvariable(ep, "s")) , unicode2native(s, 'latin-1') give me in matlab: non-latin-1 characters replaced character code 26. need getting access underlying unicode info c string in unicode format (utf-8, utf-16, etc.), , preserving non-latin-1 characters. is possible? my platform os x, matlab r2012b. addendum: documentation explicitly states "[mxarraytostring()] supports multibyte encoded characters...
