Freebasic version of PB PowerCollection
« on: January 24, 2017, 02:59:52 AM »

Extract the includes to the FB folder where Jose's cWindow lives. You'll need the latest version (RC26).

This is a wrapper on Jose's excellent CWstrDic class modeled after the Powerbasic Powercollection object.

It allows key items to be any FB basic type. Over the coming month or so, I'm also planning on taking a crack at being able to store fixed arrays as well.

Maybe Paul can use this instead of SQLite for his editor project.

Test script I used is:

Code: [Select]
#Include Once "fbcoll/cPowerCollection.inc"

Dim oPowerCollection as cPowerCollection
Dim iByte            as Byte = -1
Dim iuByte           as UByte = 255
Dim iShort           as Short = -1234
Dim iuShort          as UShort = 2345
Dim iLong            as Long = 2000000000
Dim iuLong           as uLong = 345678
Dim iInteger         as Integer = 45678
Dim iuInteger        as UInteger = 56789
Dim iLLong           as LongInt  = 300000000003
Dim iLuLong          as uLongInt = 400000000004
Dim iSingle          as Single = 12.12
Dim iDouble          as Double = 1234567890.23
Dim sString          as String = "Jose"
Dim szString         as ZString * 5 = "Paul"
Dim swString         as WString * 10 = "Freebasic"
Dim uItem            as COLLECTION_DATA
Dim iIndex           as Long
Dim sItemContent     as String
Dim arItems()        as COLLECTION_DATA

' Build a collection of different data types   

    oPowerCollection.Add("Byte",iByte)

Maybe Paul can use this instead of SQLite for his editor project.

Thanks for creating and sharing this code. Cool stuff :)

I already have a super fast hash based solution that I have implemented into the editor that I am using instead of my plan to use SQLite. It is simple, flexible, and won't have all that overhead that SQLite would have brought into the mix.

I'll take a look at it in the future. Now that I have a FB PowerCollection, LinkList and Stack should be quick wrappers base on CWStrArray.
