UTIL_ValidationRule.INT_BulkValidationContext ​

Class

apex
global interface UTIL_ValidationRule.INT_BulkValidationContext

Optional interface for bulk-optimized validation contexts. Implement this in addition to INT_SObjectFormulaEvaluationContext when your context class needs to query related data. The preLoad() method is called once per batch of records BEFORE the record loop, allowing you to perform bulk queries and cache results for use in setContext().

Since: 1.0

Example:

apex
global class VAL_AccountWithContactsContext
    implements UTIL_FormulaFilter.INT_SObjectFormulaEvaluationContext,
               UTIL_ValidationRule.INT_BulkValidationContext
{
    private Map<Id, Integer> contactCountByAccountId = new Map<Id, Integer>();
    global Integer ContactCount { get; set; }
    global void preLoad(List<SObject> newRecords, List<SObject> oldRecords)
    {
        Set<Id> accountIds = UTIL_SObject.extractIds(newRecords);
        List<AggregateResult> results = QRY_Builder.selectFrom(Contact.SObjectType)
            .count('Id')
            .groupBy(Contact.AccountId)
            .condition(Contact.AccountId).isIn(new List<Id>(accountIds))
            .toList();
        for(AggregateResult result : results)
        {
            contactCountByAccountId.put((Id)result.get('AccountId'), (Integer)result.get('count_Id'));
        }
    }
    global void setContext(SObject oldRecord, SObject newRecord)
    {
        Account account = (Account)newRecord;
        this.ContactCount = contactCountByAccountId.get(account.Id) ?? 0;
    }
}
