Value an object with a map<String field, String value>

Question

I am developing an apex code to scan an email and use some values i can found. I have a custom object used to map the labels to existing fields.

Then i have a map with field names and values. I would like to create and value an object (Lead) with this map.

Of course i don't want to list every field of the object.

I could do something like :

private void add(String field, String value){
if(field==null || value==null) return;
try{
    test.put(field, value);
}
catch(Exception e){}

try{
    test.put(field, Date.parse(value));
}
catch(Exception e){}

try{
    test.put(field, DateTime.parse(value));
}
catch(Exception e){}

try{
    test.put(field, Integer.valueOf(value));
}
catch(Exception e){}

}

Is there a cleaner way to do it ?

Thanks !

Answer 1

create a utility method some thing like

public static String getFieldType(String sObjectName, String fieldName){

Schema.SObjectType t = Schema.getGlobalDescribe().get(sObjectName);

Schema.DescribeSObjectResult r = t.getDescribe();
Schema.DescribeFieldResult f = r.fields.getMap().get(fieldName).getDescribe();

if (f.getType() == Schema.DisplayType.String){
    return 'String';
} // .... else if

return null;
}

follow above condition for boolean, date, datetime, lookup,number and then use this method to get field type and then use thios in your code. You can also use this in multiple place also it is easy to handle.
