Map keys when declared String are case-sensitive for example, ABC and abc will be considered as different keys and treated as unique. Map values may be unordered and hence we should not rely on the order in which the values are stored and try to access the map always using keys. bug('Value of Set with Keys '+SetOfKeys) Set SetOfKeys = ProductCodeToProductName.keySet() Return a set that contains all of the keys in the map bug('Value at the Specified key using get function: '+value) String value = ProductCodeToProductName.get('1002')

Retrieves a value, given a particular key bug('If output is true then Map contains the key and output is:' Assert that the map contains a specified key and respective value ProductCodeToProductName.put('1003', 'Ketone') Insert a new key-value pair in the map where '1003' is key and 'Ketone' is value ProductCodeToProductName.put('1002', 'Acetone') Insert a new key-value pair in the map where '1002' is key and 'Acetone' is value Map ProductCodeToProductName = new Map() bug('value of ProductCodeToProductName'+ProductCodeToProductName) įollowing are a few examples which demonstrate the methods that can be used with Map − This statement would give as output as key value pair in Debug log The following example represents the map of the Product Name with the Product code. Both key and value can be of any data type. It is a key value pair which contains the unique key for each value. bug('Value of Set with all values '+ProductSet) Check whether set contains the particular element or not and returns true or false bug('Set with removed value '+ProductSet) Following is an example which shows the same.

However, we will declare the initial values here. salesforce/apex import getOpps from salesforce/apex/AccountController. bug('Value Of ListOfCities'+ListOfCities) ĭeclaring the initial values of list is optional. A list should be declared with the keyword 'List'.īelow is the list which contains the List of a primitive data type (string), that is the list of cities. This is one of the most important type of collection and also, it has some system methods which have been tailored specifically to use with List. List can contain any number of records of primitive, collections, sObjects, user defined and built in Apex type. Let us now have a detailed overview of all collection types. For example, List can store multiple number of Account object's records.

Be aware that in an insert trigger, you cannot reference Trigger.old or Trigger.oldMap, so be sure to only reference old records from the update context.Collections is a type of variable that can store multiple number of records.

Trigger.newMap, Trigger.oldMap: same records, but as a Map: Map.

oldMap contains the Opportunity record prior to the update, and newMap contains the record after the update. In an Opportunity trigger, both are of type Map.

In an update trigger, you can call Trigger.newMap and Trigger.oldMap to see changes between records.

Methods only called from the same class should be kept private.

Ensure class access is set up correctly.

Keep triggers logic-less and call logic in a handler.

We don’t want to run the calculations on update if neither Amount nor Tax_Percentage_c are changed in the update.

We don’t want to run the calculations if Amount or Tax_Percentage_c are not populated (to avoid errors).

Need to convert Tax_Percentrage_c to a decimal value to multiply by Amount.

Fields should be calculated as follows:.

Calculate tax any time an Opportunity is inserted or updated.

Also includes the Challenge 1 opportunity page layout.

The setup from Mike Wheeler’s content includes the following custom fields on Opportunity (included in this package):.

Long - lets you have a higher-precision Integer.Object - generic Apex datatype, all primitives and more complex types are of type Object.Blob - commonly used for Salesforce files.There are many interesting “helper methods” available by typing the datatype and.Apex does some datatype checking, so you cannot assign the string 'true' (instead of true) to a Boolean variable as it generates an “Illegal Assignment” error.Range from simple Strings to complex DateTimes.Primitive data types are the most basic type of variable you can have in Apex.For example, initialize Boolean variables to false. Initiatlize variabbles to appropriate values before using them.

All Apex variables (both class member variables and method variables) are initialized to null.

All primitive data types are passed by value.Apex uses the same primitive data types as SOAP API, except for higher-precision Decimal type in certain cases.These notes were taken while studying using Mike Wheeler's Salesforce Courses.
