#Code Snippet

This code snippet determines the day of the week associated with a date. The class method "test" takes a date as a string in "mm/dd/yyyy" format, and returns an integer corresponding to a day of the week:

Class cartertiernan.getDayfromDate Extends %RegisteredObject
{
    classmethod test(date) as %Integer {
        //Set date = $ZDATE(date) //  Looks like: mm/dd/yyyy
     
        Set monthList = $LISTBUILD(0,3,3,6,1,4,6,2,5,0,3,5) // (Jan,Feb,Mar,Apr,...)
        Set centuryList = $LISTBUILD(6,4,2,0) // first two digits divisiable by 4, then subsequent centuries. EX (2000, 2100, 2200, 2300)
        Set dayList = $LISTBUILD("Sunday","Monday","Tuesday","Wednesday","Thursday","Friday","Saturday") // Index goes from 0-6
         
        Set day = $PIECE(date,"/",2) // get the day 
        Set monthVal = $LIST(monthList,($PIECE( date,"/",1 ))) // get the month value
        Set first2DigsYear = $PIECE( date,"/",3 ) \ 100 // get the last 2 digits of the year
        Set last2DigsYear = $PIECE( date,"/",3 ) # 100 // get the first 2 digits of the year
         
        // Used for DEBUG perpouses
        /*write !,"day: ",day
        write !,"Month: ",monthVal
        write !,"last2: ",last2DigsYear
        write !,"first2: ",first2DigsYear
        write !,"cen Val: ",$LIST(centuryList,(first2DigsYear # 4) + 1),!!*/
         
        // Look here for formula explination (its the "Basic method for mental calculation")
        // http://en.wikipedia.org/wiki/Determination_of_the_day_of_the_week
        Set dayOfWeekVal = ( day + monthVal + last2DigsYear + (last2DigsYear\4) + $LIST(centuryList,(first2DigsYear # 4) + 1 ) ) # 7
     
        Quit dayOfWeekVal
    }
}

The following class method "test" contains code that can create a new class, create new properties for classes, or create new methods for classes. "test" runs all three of these processes once, and the code that performs each action is labelled by comments in the method:

ClassMethod test() As %Status
{
    set sc = $$$OK
    
    // Create a class
    set class = ##class(%ClassDefinition).%New("MyClass")
    set class.Description = "This is my test class"_$c(13,10)_"testing %ClassDefinition"
    set class.Super = "%Persistent"

    // Create a property and add it
    set property = ##class(%PropertyDefinition).%New("MyClass.MyProperty")
    set property.Type = "%String"
    set property.Description="This is a property"
    set sc1 = class.Properties.Insert(property)
    do:$$$ISERR(sc1) $system.Status.DisplayError(sc1)
    set sc = $$$ADDSC(sc, sc1)
    
    // Create a method and add it
    set method = ##class(%MethodDefinition).%New("MyClass.MyMethod")
    set method.ReturnType = "%Integer"
    set method.FormalSpec = "x:%Integer,y:%Integer=10"
    set method.Description = "Return product of x and y"
    set method.CodeMode = "code"
    set method.Code = " new result"_$c(13,10)_" set result=x*y"_$c(13,10)_" quit result"
    set sc2 = class.Methods.Insert(method)
    do:$$$ISERR(sc2) $system.Status.DisplayError(sc2)
    set sc = $$$ADDSC(sc, sc2)
    
    // Save the class definition
    set sc3 = class.%Save()
    do:$$$ISERR(sc3) $system.Status.DisplayError(sc3)
    set sc = $$$ADDSC(sc, sc3)
    
    return sc
}

Today, you need to make a compiler for the language assembunny.
Luckily, this language has only 4 instructions :

Tip dvacátý šestý: objekty a concurrency 2 - swizzling

Když tento seriál před několika lety začínal, byl jeho první díl věnován zajištění izolace instance objektů pro exkluzivní přístup a popisu příslušných API funkcí. Nedávno se mi ale stalo, že mě tento díl dostihl. Jeden ze zákazníků začal mít problémy v aplikaci, přestože důsledně používal exkluzivní zámky pro editování instancí svých objektů.

This code snippet contains the class method "test" which sends an HTML email. Change the literal strings in the method to customize the email's from address, to address, subject, and body:

Class objectscript.sendEmail Extends %RegisteredObject
{
    classmethod test() {
        set m=##class(%Net.MailMessage).%New()
        set m.From="user@company.com"
         
        set m.IsHTML=1
         
        do m.To.Insert("user@company.com")
        set m.Subject="Sent by IRIS mail"
        set m.Charset="iso-8859-1"
        do m.TextData.Write("<HTML><HEAD><TITLE></TITLE>"_$char(13,10))
        do m.TextData.Write("<META http-equiv=Content-Type content=""text/html; charset=iso-8859-2""></HEAD>"_$char(13,10))
        do m.TextData.Write("<BODY><FONT face=Arial size=2>Test <B>Test</B></FONT></BODY></HTML>")
        set s=##class(%Net.SMTP).%New()
        set s.smtpserver="mail.company.com"
        set status=s.Send(m)
    }
}

The attached zip file contains a bunch of examples of Cache SQL Storage mappings that I have done over the years.

If you have existing globals and want to expose them via Objects or SQL you need to setup Cache SQL Storage mapping. If you do not see an example that helps with your case send me an example and I can help you out.

The following code walks a DOM using %XML.Node. It also prevents %XML.Writer to change whitespace. Run the code using the class method "test":

Class objectscript.walkDOM Extends %Persistent
{
    ClassMethod dfs(node As %XML.Node)
    {
        s entrynode=node.NodeId
        do {
        //element nodes with one whitespacetyped child are the ones we want to change
        if (node.NodeType=$$$xmlELEMENTNODE){
            s snode=node.NodeId     
            if (node.MoveToFirstChild())            
                {
                    i ('node.MoveToNextSibling()){

Hi,

it seems the community markdown engine doesn't support regular ``` as marking for code.
