# Apex FP

Apex FP provides functional constructs for `SObject` collections!

## Examples

Transform `SObjects` with a simple declarative API.

```apex

List largeOpportunities = SObjectCollection.of(opportunities)

	.filter(Fn.Match

		.field(Opportunity.Amount).greaterThan(150000)

		.also(Opportunity.AccountId).equals(accountId))

	.asList();

```

```apex

List 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))

	.asList();

```

```apex

Map> accountsByParentId = SObjectCollection.of(accounts).groupByIds(Account.ParentId);

```

```apex

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

```
