An object to facilitate dynamic arrays in types

Check the tests to see how it works. Feel free to ask any questions you may have.

SRC + Win32 Binaries: http://fileanchor.com/87839-d

I'll post the array in type test:

Code: Select all

#include "../array.bi"

type testing_type
    
    '' 3 dynamic arrays, with 0 - 9
	integer_array as dynamicArray(integer) = 10
	double_array as dynamicArray(double) = 10
	string_array as dynamicArray(string) = 10
	
end type

dim as testing_type this_is_only_a_test

'' put crap in them
for i as integer = 0 to 9
	this_is_only_a_test.string_array.data(i)  = str( 10 - i )
	this_is_only_a_test.integer_array.data(i) = 10 - i
	this_is_only_a_test.double_array.data(i)  = 10 - i
next

'' print em
print "Strings:"
print this_is_only_a_test.string_array
print 
print "Integers:"
print this_is_only_a_test.integer_array
print 
print "Doubles:"
print this_is_only_a_test.double_array
print 

'' resize them, 0 - 19
this_is_only_a_test.string_array.redim(20)
this_is_only_a_test.integer_array.redim(20)
this_is_only_a_test.double_array.redim(20)

'' put crap in them
for i as integer = 10 to 19
	this_is_only_a_test.string_array.data(i)  = str( 10 - i )
	this_is_only_a_test.integer_array.data(i) = 10 - i
	this_is_only_a_test.double_array.data(i)  = 10 - i
next

'' print em
print "Strings:"
print this_is_only_a_test.string_array
print 
print "Integers:"
print this_is_only_a_test.integer_array
print 
print "Doubles:"
print this_is_only_a_test.double_array
print

Yeah, there's a cast to string, so you can print arrays like a normal variable.

Changelog:

-Added copy ctors, to make 'var = dynamic_array' safe.
-Fixed CAST to return a pointer of type, instead of ANY.
-Iterated in dtor, if strings, to free string mem.
-Changed 'exit sub' to 'exit constructor' (You'll now need a pretty recent CVS to compile it...)
-The library now does not contain any information about itself's location anymore, due to preprocessor directives.

great work :)

For a moment i was like.. what the.. since when FB supports templates (the "type dynamicArray( __TYPE__ ) part"), great trick :).

Btw, with data being stored in objects, you should never use #libpath or #inclib with absolute paths, for example, libarray.a includes: "D:\prg\fb\cha0s\chi\dynarray".

you probably using an old version of fb. get latest fb cvs build (see under Linux/windows/dos -whatever platform you use) thread for daily builds.

im afraid to do that... everytime i do it feels like a new programming language... everythin i have gets 100+ errors...

I'm like that but my situation's the opposite. When I update I'm afraid to use older versions because I tend to code cleanly with the newest features available. Oh wait nvr mind,

-lang deprecated

You should think about using it. Or -lang qb at least

Yeah, you used to have to do 'exit sub' instead of 'exit construtor', after rebuilding my CVS and the library, I found that. Thanks.

Original post updated.

Could it be possible to have a default property for a class/type? Something like "declare property foo default (parameters)" ? That way, you could make the data property default, so you could do array(index) instead of array.data(index) .

That'd be awesome.
