Some of Setup Objects in Salesforce.com

Hi,
The following are the Setup Objects in Salesforce.com.
I got this  from "http://www.salesforce.com/us/developer/docs/api_toolingpre/api_tooling.pdf".
You can get more information from the above link.

Object	Descripion
CompactLayout	Represents the values that define a compact page layout.
CustomField	Represents a custom field on a custom object that stores data unique to your organization.
CustomObject	Represents a custom object that stores data unique to your organization. Includes access to the associated CustomObject object and related fields in Salesforce Metadata API.
EmailTemplate	Represents an email template
EntityDefinition	Provides row based access to metadata about standard and custom objects.
FieldDefinition	Provides row based access to metadata about standard and custom fields of standard and coustom objects.
FlexiPage	Represents a Lightning Page. A Lightning Page is the home page for an app that appears as a menu item in the Salesforce1 navigation menu. Includes access to the associated FlexiPage object in the Salesforce Metadata API.
Layout	Represents a page layout. For more information, see “Managing Page Layouts” in the Salesforce online help.
MenuItem	Represents a menu item.
Profile	Represents a user profile. A profile defines a user's permission to perform different functions within Salesforce.
ProfileLayout	Represents a profile layout.
QuickActionDefinition	Represents the definition of a quick action.
QuickActionList	Represents a list of quick actions.
QuickActionListItem	Represents an item in a quick action list
RecordType	Represents a custom record type.
User	Represents a user.
ValidationRule	Represents a formula that is used for specifying when a criteria is met. This includes both validation rules and workflow rules. Includes access to the associated ValidationRule object in the Salesforce Metadata API.
WorkflowAlert	Represents a workflow alert. A workflow alert is an email generated by a workflow rule or approval process and sent to designated recipients
WorkflowFieldUpdate	Represents a workflow field update
WorkflowOutboundMessage	Represents an outbound message. An outbound message is a workflow, approval, or milestone action that sends the information you specify to an endpoint you designate, such as an external service. Outbound messaging is configured in the Salesforce setup menu. Then you must configure the external endpoint. You can create a listener for the messages using the SOAP API.
WorkflowRule	Represents a workflow rule that is used to fire off a specific workflow action when the specified criteria is met. Includes access to the associated WorkflowRule object in Salesforce Metadata API.
WorkflowTask	Represents a workflow task that is used to fire off a specific workflow action when the specified criteria is met. Includes access to the associated WorkflowRule object in Salesforce Metadata API.

Generation of JSON String , Deserialize and Serialize

Hi,
We have a small example ,how to generate json .The below code is used for  generating json string.
To generate JSON string we have to use "JSONGenerator " and "createGenerator(true)" method.



JSONGenerator gen=JSON.createGenerator(true);
gen.writeStartArray();
gen.writeStartObject();
gen.writenumberField('StudentNumber',1);
gen.writeStringField('StudentName','Balaji');
gen.writeEndObject();
gen.writeStartObject();
gen.writenumberField('StudentNumber',2);
gen.writeStringField('StudentName','Shilpa');
gen.writeEndObject();
gen.writeEndArray();
String jsonString= gen.getAsString();
System.debug('jsonString:'+jsonString);

Output:
=====
jsonString:[ {
"StudentNumber" : 1,
"StudentName" : "Balaji"
 }, {
  "StudentNumber" : 2,
   "StudentName" : "Shilpa"
  } ]

To deserialize the above json string ,we have to prepare a class as shown below.
Class:
======
public class Studentscls{
    public Class StudentDetail{
        public integer StudentNumber{get;set;}
        public String StudentName{get;set;}  
    }
}

Execution:
------------
To deserialize JSON string we have "deserialize" method as shown below by using above class.

List<Studentscls.StudentDetail>  studentList = (List<Studentscls.StudentDetail>)JSON.deserialize(jsonString,List<Studentscls.StudentDetail>.class);
System.debug('Deserialized Result:'+studentList);

OuptPut:
======
Deserialized Result:(StudentDetail:[StudentName=Balaji, StudentNumber=1], StudentDetail:[StudentName=Shilpa, StudentNumber=2])

To serialize above list we have to user "serialize()" method as shown below.
--------------------------------------------------------------------------------------------

String studentJSONString=Json.serialize(studentList);
System.debug('Student JSONString:'+studentJSONString);

Output:
=====

Student JSONString:
[{"StudentNumber":1,"StudentName":"Balaji"},{"StudentNumber":2,"StudentName":"Shilpa"}]

Wrapper List Sorting(Column Sorting) using Comparable Interface

Comparable Interface adds sorting support for Lists that contain non-primitive types, that is, Lists of user-defined types.

Whenever we want to achieve column sorting in wrapper list then we have to implement Comparable and we should define the "compareTo" method as shown below.

Here i am querying the account object records and passing them to wrapper list for giving example. Basically a wrapper class can contain combination of different types. For all such type of things also it will work.Comparable interface is very useful for sorting wrapper list.

Class:

======

public class AccountClass {

    public List<AccountWrappercls> wrapperList{get;set;}

    public string sortableField{get;set;}

    public string sortOrder{get;set;}

    public string previoussortfield{get;set;}

    public AccountClass(){

        wrapperList = new List<AccountWrappercls>();

        sortableField = 'name';

        sortOrder = 'asc';

        previoussortfield =sortableField;

        for(Account actobj:[select id,name,ActiveDate__c,ACnumber__c from Account where ActiveDate__c!=null and ACnumber__c!=null]){

                AccountWrappercls wrapObj = new AccountWrappercls(actobj.ActiveDate__c,actobj.Acnumber__c,actobj.name);

                wrapperList.add(wrapObj);

        }           

        wrapperList.sort();

    }

    public pagereference doSort(){      

        //sortorder='asc';      

        if(previoussortfield == sortableField){

            sortorder='desc';

            previoussortfield=null;

        }

        else{

            sortorder='asc';            

            previoussortfield=sortableField;

        }

        System.debug('sortableField:::'+sortableField);

        System.debug('sortOrder::'+sortOrder);

        AccountWrappercls.sortableField = sortableField;

        AccountWrappercls.sortorder = sortOrder;        

        wrapperList.sort();

        return null;

    }

}

Class Which Implements Comparable interface:

======================================

public  class AccountWrappercls implements comparable{
  public Date createdDate {get;set;}
  public decimal num1 {get;set;}
  public String  name {get;set;}
  public static String sortableField='name';
  public static String sortOrder='asc';  
  public AccountWrappercls(Date createdDate,decimal num1,String  name){
      this.createdDate = createdDate;
      this.num1 = num1;
      this.name =name;
      //this.sortableField = sortableField;
      //this.sortOrder = sortOrder;
  }
   public  Integer compareTo(Object compareTo) {
     AccountWrappercls compWrap = (AccountWrappercls)compareTo;
     if(sortOrder == 'asc'){
    if(sortableField == 'num1'){     
            if (num1 == compWrap.num1) return 0;
          if (num1 > compWrap.num1) return 1;
          return -1;        
    }
    if(sortableField == 'name'){     
            if (name == compWrap.name) return 0;
          if (name > compWrap.name) return 1;
          return -1;        
    }
    if(sortableField == 'createdDate'){     
            if (createdDate == compWrap.createdDate) return 0;
          if (createdDate > compWrap.createdDate) return 1;
          return -1;        
    }}else{
      if(sortableField == 'num1'){     
            if (num1 == compWrap.num1) return 0;
          if (num1 > compWrap.num1) return -1;
          return 1;        
    }
    if(sortableField == 'name'){     
            if (name == compWrap.name) return 0;
          if (name > compWrap.name) return -1;
          return 1;        
    }
    if(sortableField == 'createdDate'){     
            if (createdDate == compWrap.createdDate) return 0;
          if (createdDate > compWrap.createdDate) return -1;
          return 1;        
    }
    }
    
    return null;
    }    
    
}
