Class VirtualDescriptor

java.lang.Object

io.helidon.service.registry.VirtualDescriptor

All Implemented Interfaces:

Weighted, ServiceDescriptor<Object>, ServiceInfo, Comparable<Weighted>

public class VirtualDescriptor
extends Object
implements ServiceDescriptor<Object>

A virtual descriptor is not backed by a generated descriptor.

Method Details

serviceType

public TypeName serviceType()

Description copied from interface: ServiceInfo

Type of the service this descriptor describes.

Specified by:

serviceType in interface ServiceInfo

Returns:

service type

descriptorType

public TypeName descriptorType()

Description copied from interface: ServiceInfo

Type of the service descriptor (usually generated).

Specified by:

descriptorType in interface ServiceInfo

Returns:

descriptor type

contracts

public Set<ResolvedType> contracts()

Description copied from interface: ServiceInfo

Set of contracts the described service implements or provides through a factory method.

Specified by:

contracts in interface ServiceInfo

Returns:

set of contracts

weight

public double weight()

Description copied from interface: Weighted

Weight of this class (maybe because it is defined dynamically, so it cannot be defined by an annotation). If not dynamic, you can use the Weight annotation rather than implementing this interface as long as it is supported by the library using this Weighted.

Specified by:

weight in interface Weighted

Returns:

the weight of this service, must be a non-negative number

qualifiers

public Set<Qualifier> qualifiers()

Description copied from interface: ServiceInfo

Service qualifiers.

Specified by:

qualifiers in interface ServiceInfo

Returns:

qualifiers

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object o)

Overrides:

equals in class Object

toString

public String toString()

Overrides:

toString in class Object
