Method Details

externalContractsImplemented

Set<String> externalContractsImplemented()

The managed services external contracts / interfaces. These should also be contained within ServiceInfoBasics.contractsImplemented(). External contracts are from other modules other than the module containing the implementation typically.

Returns:

the service external contracts implemented

activatorTypeName

Optional<String> activatorTypeName()

The management agent (i.e., the activator) that is responsible for creating and activating - typically build-time created.

Returns:

the activator type name

moduleName

Optional<String> moduleName()

The name of the ascribed module, if known.

Returns:

the module name

matches

default boolean matches(ServiceInfoCriteria criteria)

Determines whether this service info matches the criteria for injection. Matches is a looser form of equality check than equals(). If a service matches criteria it is generally assumed to be viable for assignability.

Parameters:

criteria - the criteria to compare against

Returns:

true if the criteria provided matches this instance

matchesQualifiers

static boolean matchesQualifiers(Collection<QualifierAndValue> src,
 Collection<QualifierAndValue> criteria)

Matches qualifier collections.

Parameters:

src - the target service info to evaluate

criteria - the criteria to compare against

Returns:

true if the criteria provided matches this instance

toBuilder

static io.helidon.pico.api.DefaultServiceInfo.Builder toBuilder(ServiceInfoBasics val)

Creates a builder from a ServiceInfoBasics instance.

Parameters:

val - the instance to copy

Returns:

the fluent builder
