ClearTable(certainvar) ?

04-25-2006, 10:51 AM

Since I started using tables instead of handle vars, I have a bit of a problem. I only have a ClearTable(string) which does this:

JASS:

function ClearTable takes string table returns nothing
     call FlushStoredMission(Cache(),table)
endfunction

Thing is, what if I want to clear a certain variable inside a table? which function I should make?
I remember I made this for the handle vars but it acts kind of differently for tables.

I want to be able to clear a certain var from a table. For example:

JASS:

local string s = GetAttachmentTable(s, unit)
call SetTableBoolean(s, "b", true)

Then I want only to clear the "b" value, and not the entire table.
Can anyone help me with this? Thanks.

I've never looked at this implementation of tables but what you want to accomplish translates to

JASS:

FlushStoredBoolean(Cache(), s, "b")

Vexorian might also have implemented an auto-flush on default value behavior,
in which case you'd simply use

JASS:

SetTableBoolean(s, "b", false)

to remove the value from the table.

But that's pure speculation, as already mentioned I've never checked the implementation.

hmm now that i'm looking at it;

JASS:

function SetTableObject takes string table, string field, handle val returns nothing
    local gamecache g=Cache()
    if (val==null) then
        call FlushStoredInteger(g,table,field)
    else
        call StoreInteger(g,table,field,H2I(val))
    endif
    set g=null
endfunction

It seems that if the value is null than it flushes the certain var

so if I use

JASS:

call SetTableObject(s, "u", null)

"u" will be flushed. Is this correct?

PitzerMike	Yes, correct. That's what I meant with "auto-flush on default value". For booleans it would be false, for strings either null or "" and for numeric types 0.

vile	Thanks mate.
