Fn

Fn is the main function factory providing access to function builders and predicates for working with SObjects.

NotNull​

A static instance of SObjectNotNull predicate that returns true when an SObject is not null.

Example

List<Account> accounts = new List<Account>{acc1, null, acc2};
SObjectCollection nonNull = SObjectCollection.of(accounts).filter(Fn.NotNull);

Match​

A static instance of MatchSObject providing methods to build field matching predicates.

Match.recordFields()​

Builds a MatchRecordFields predicate that returns true when applied to a record which matches all fields defined on the prototype record. Fields that are not defined on the prototype are not checked for equality.

Signature

MatchRecordFields recordFields(SObject prototype)

Example

MatchRecordFields isMatch = Fn.Match.recordFields(new Account{Name = 'Foo'});
isMatch.call(new Account{Name = 'Foo', Description = 'Some description'}); // true
isMatch.call(new Account{Name = 'Bar'}); // false

Match.field()​

Starts the construction of a field criteria matching function by defining a field. The field can be defined as a Schema.SObjectField or given as a String relation. Returns an IncompleteMatchFields which can be completed into a MatchFields by invoking comparison methods on it.

Signature

IncompleteMatchFields field(Schema.SObjectField field)
IncompleteMatchFields field(String fieldPath)

Example

MatchFields amountCheck = Fn.Match.field(Opportunity.Amount).lessThan(10000);
MatchFields parentCheck = Fn.Match.field('Parent.Id').equals(accountId);

Modify​

Returns a new ModifySObject function builder for modifying SObject fields.

Example

ModifySObject updateStatus = Fn.Modify.setField(Account.Status__c, 'Active');
updateStatus.call(myAccount);

MapTo​

Returns a new mapping function to transform SObjects.

MapTo(Schema.SObjectType)​

Returns a new MapToSObject function for mapping SObjects to a different SObject type.

Signature

MapToSObject MapTo(Schema.SObjectType type)

MapTo(Type)​

Returns a new MapToObject function for mapping SObjects to custom Apex objects.

Signature

MapToObject MapTo(Type type)
