Apex utility class for email send

Question

I have below method to send email. Now I need to do the same from a separate utility class where I will have to pass toAddress , ccaddress , parameter string which has a map with Email template , suppose (A -> 'Email Template 1' , B -> 'Email Template 2' etc.)

Can someone let me know how to create such an utility or if such available to feed directly?

Publish method:

public void Publish() {
    Set < String > tempSet = new Set < String > ();
    List < String > sendTo = new List < String > ();
    List < ID > CIdlist = new List < ID > (); //Send to future
    chkpublish = true;
    ispublish = true; //Connfirm button hide
    List < Compliance_Incident_abv__c > selIncs = (List < Compliance_Incident_abv__c > ) contr.getSelected();
    for (Compliance_Incident_abv__c inc: selIncs) {

        inc.status_abv__c = 'Open';
        inc.Publish_Date_abv__c = Date.today();
        if (inc.Rep_abv__c != null) inc.OwnerId = inc.Rep_abv__c;

        CIdlist.add(inc.id); //Add id
    }
    update selIncs;

Answer 1

You would create a class that looks something like this:

public with sharing class MyEmailHandler{

//declare public variables (possibly with {get;} but no setters)

    //constructor

    public void MyEmailHandler(list<string> toAddresses, list<string> ccaddresses, map<string,string>param2Emailtemplate){

        // You can use this.toAddresses = toAddresses type notation if you wish 
        // provided you declared the variables in 1st section above.

        // You can call a method to process the above variables, simply put all the code here
        // from your original class, or allow that code to follow below. 

        // It's unclear to me which portions you want to include, so I've omitted.


    { 

    //You could also use a no constructor class and just declare a method as below that 
    //you go directly to OR just do all the work in your constructor as above
    // except the DML which cannot be done in a constructor.

    public void MyEmailHandlerMethod(list<string> toAddresses, list<string> ccaddresses, map<string,string>param2Emailtemplate){

       // code for processing the above data that also does the email DML or calls other methods
       // to do various parts of the work, but returns nothing (thus the reason for keyword void). 

    }

}

Note: I don't think you need to use the static keyword, only void. I could be mistaken on not needing to use static.
