[SalesForce] Get FieldType and Cast String As

I have a list of sObjectsToInsert which will be inserted at the end of a set of scripts. It will contain many different sObjectTypes, so it must be built dynamically (get/put).

One problem I'm running into is when a field type is a non-string, yet I'm passing a string value through via values.get(value)

public void addToInsert(sObject so, Map<String, String> values) {
    for (String value : values.keySet()) {
        so.put(value, values.get(value));
    }
    sObjectsToInsert.add(so);
}

How can I cast values.get(value) as the value field type dynamically?

Change Map<String, String> values to Map<String, Object> values and no casting should be needed.

It is also normally better to use SObjectField as the type of the key in this sort of map.

Be careful about the ordering of the different types in the list: Google "Updating Records for Different Object Types" to read about "chunks".

[SalesForce] SObject constructor signature

This is a named parameter language feature that is only supported for specific SObject types and nowhere else in Apex. It makes code where you want to assign several values cleaner - see this example. Agreed that the documentation isn't good on this.

If you want to initialise from a map, you have to write your own utility method such as:

public void someMethod() {
    ...
    Account a = (Account) init(new Account(), new Map<SObjectType, Object> {
            Account.Name => 'Acme',
            Account.BillingCity => 'San Francisco'
            });
    ...
}

private SObject init(SObject sob, Map<SObjectField, Object> values) {
    for (SObjectField field : values.keySet()) {
        sob.put(field, values.get(field));
    }
    return a;
}

that makes use of SObject.put(SobjectType, Object).

You can also use strings as the keys (though you lose the compile-time checking that the field names are valid) as there is also SObject.put(String, Object).
