Namespace
Formula Methods
The following are methods for Formula.
builder()
Creates an instance of FormulaBuilder for configuring
the formula with formula expression, context type, and output data type as inputs.
Signature
public static formulaeval.FormulaBuilder builder()
Return Value
recalculateFormulas(sobjects)
Signature
public static List<System.FormulaRecalcResult> recalculateFormulas(List<SObject> sobjects)
Parameters
- sobjects
- Type: List<SObject>
- List of sObjects whose formula fields are to be recalculated.
Return Value
Type: List<FormulaRecalcResult Class>
Usage
Recalculate formula fields on new or queried SObjects. If all data is present on the SObjects, SOQL limits are not affected. If the data required to evaluate a formula field is missing, that data is retrieved and limits are changed accordingly.
The new formula values are stored in the SObjects themselves and overwrite previous values of formula fields.
Example
Account a = new Account();
a.Name = 'Salesforce';
a.BillingCity = 'San Francisco';
List<Account> accounts = new List<Account>{a};
List<FormulaRecalcResult> results = Formula.recalculateFormulas(accounts);
System.assert(results[0].isSuccess());
// Option 1
System.debug('New value: ' + accounts[0].get('My_Formula_Field__c'));
// Option 2
System.debug('New value: ' + results[0].getSObject().get(‘My_Formula_Field__c’));
