SObjectStream

SObjectStream is a lazy collection of SObject instances which implements Iterator<SObject>.

of

Constructs an SObjectStream with the provided Iterable<SObject>.

Signature

static SObjectStream of(Iterable<SObject> records)

Example

// List<Accounts> accounts = [...]SObjectStream.of(accounts);SObjectStream.of(Trigger.old);

hasNext

Signature

virtual Boolean hasNext()

Example

SObjectStream accountStream = SObjectStream.of(Trigger.new); while (accountStream.hasNext()) { Account acc = (Account) accountStream.next(); }

next

Signature

virtual SObject next()

Example

SObjectStream largeOpportunities = SObjectStream.of(Trigger.new).filter(Fn.Match.field(Opportunity.Amount).gt(100000));while (largeOpportunities.hasNext()) {    Opportunity opp = (Opportunity) largeOpportunities.next();}

filter

Returns a stream consisting of the elements of this stream that match the given predicate.

Signature

SObjectStream filter(SObjectPredicate predicate)

find

Returns an OptionalSObject wrapping the first record predicate returns true for, or an empty OptionalSObject if no element is found. This consumes the stream.

Signature

OptionalSObject find(SObjectPredicate predicate)

forEach

Iterates through the stream and invokes a function for each record. This consumes the stream.

Signature

void forEach(SObjectFunction fn)

mapAll

Signature

SObjectStream mapAll(SObjectToSObjectFunction fn)

mapSome

Signature

SObjectStream mapSome(SObjectPredicate predicate, SObjectToSObjectFunction fn)

remove

Returns a stream consisting of the elements of this stream that do not match the given predicate.

Signature

SObjectStream remove(SObjectPredicate predicate)

Example

toList

Collects the stream into a List. This consumes the stream.

Signature

List<SObject> toList()
