Filtering

SObjectCollection

Find opportunities over 150,000

// List<Opportunity> opportunities = ...SObjectCollection.of(opportunities).filter(Fn.Match.field(Opportunity.Amount).greaterThan(150000));

Find opportunities over 150,000 that belong to a specific account

// List<Opportunity> opportunities = ...// Id accountId = ...SObjectCollection.of(opportunities).filter(Fn.Match.field(Opportunity.Amount).greaterThan(150000).also(Opportunity.AccountId).equals(accountId));

Grouping

SObjectCollection

Group accounts by parent accounts

Map<Id, List<Account>> accountsByParentId = SObjectCollection.of(accounts).groupByIds(Account.ParentId);

Mapping

SObjectCollection

Create tasks for opportunities of specific stage in a trigger

List<Task> prospectingTasks = SObjectCollection.of(Trigger.new)    .filter(Fn.Match.recordFields(new Opportunity(Stage = 'Prospecting')))    .mapAll(Fn.MapTo(Task.SObjectType).setField(Task.Subject, 'Follow up').mapField(Task.WhatId, Opportunity.Id));

Find average opportunity value

OptionalDecimal averageOpportunityValue = SObjectCollection.of(opportunities).mapToDecimal(Opportunity.Amount).average();

Pluck opportunity values

List<Decimal> opportunityValues = SObjectCollection.of(opportunities).pluckDecimal(Opportunity.Amount);
