Get Ids of Org Wide Email Addresses Without SOQL

Question

Is there a method in which we can get all the org wide email addresses in an org with their Ids without using SOQL? I was hoping that there would be something similar to the getall method for Custom Settings or the getUserInfo class but I can't find anything.

Motivation: Just avoiding a SOQL query to the transaction.

Update:

This is what I am planning on implementing if we have to use SOQL

public static map<String,OrgWideEmailAddress> emailMap{
    get{
        if(emailMap== null){
            emailMap= new Map<String, OrgWideEmailAddress>();
            List<OrgWideEmailAddress> emailList= [SELECT Id, Address FROM OrgWideEmailAddress];
            For(OrgWideEmailAddress o : emailList){
                orgEmailMap.put(o.Address, o);               
            }
        }
        return emailMap;      
    }
    set;
}

Org Wide email address fetching is only really available through Apex, so, what I would do is create a new method in your Util class that returns the list of org Wide email addresses in some useful way. You will want to cache the results of the SOQL so if multiple aspects of your transaction need to fetch org wide email addresses (e.g. a set of linked triggers and/or services), the SOQL is only done once since it is unlikely that you will be adding new org wide email addresses in the middle of a transaction

Here's an example (I changed some variable names to match my conventions from your OP):

public static map<String,OrgWideEmailAddress> emailAddressToOrgWideEmailMap{
    get{
        if(emailAddressToOrgWideEmailMap== null){
            emailAddressToOrgWideEmailMap= new Map<String, OrgWideEmailAddress>();
            for (OrgWideEmailAddress owea= [SELECT Id, Address FROM OrgWideEmailAddress])
                emailAddressToOrgWideEmailMap.put(owea.Address, owea);               
        }
        return emailAddressToOrgWideEmailMap;      
    }
    set; // keep public if you want to inject a known value in testmethods
}

public static SelectOption[] getOrgWideEmailAddressPickList() {
  SelectOption[] res = new List<SelectOption>();
  for (String emailAddr : emailAddressToOrgWideEmailMap)
     res.add(new SelectOption(emailAddressToOrgWideEmailMap.get(emailAddr).id,emailAddr));   
  return res;
}
