Constructor Details

ServiceRegistryConfigImpl

protected ServiceRegistryConfigImpl(ServiceRegistryConfig.BuilderBase<?,?> builder)

Create an instance providing a builder.

Parameters:

builder - extending builder base of this prototype

Method Details

discoverServices

public boolean discoverServices()

Description copied from interface: ServiceRegistryConfig

Whether to discover services from the class path. When set to false, only services added through ServiceRegistryConfig.serviceDescriptors() and/or ServiceRegistryConfig.serviceInstances() would be available.

Specified by:

discoverServices in interface ServiceRegistryConfig

Returns:

whether to discover services from classpath, defaults to true

discoverServicesFromServiceLoader

public boolean discoverServicesFromServiceLoader()

Description copied from interface: ServiceRegistryConfig

Whether to discover services from Java service loader. See ServiceDiscovery.SERVICES_LOADER_RESOURCE.

Specified by:

discoverServicesFromServiceLoader in interface ServiceRegistryConfig

Returns:

whether to discover Java ServiceLoader services from classpath (a curated list only), defaults to true

allowLateBinding

public boolean allowLateBinding()

Description copied from interface: ServiceRegistryConfig

Whether to allow binding via methods, such as Services.set(Class, Object[]). When disabled, attempts at late binding will throw an exception.

Specified by:

allowLateBinding in interface ServiceRegistryConfig

Returns:

whether late binding is enabled, defaults to true

serviceDescriptors

public List<ServiceDescriptor<?>> serviceDescriptors()

Description copied from interface: ServiceRegistryConfig

Manually registered service descriptors to add to the registry. This is useful when ServiceRegistryConfig.discoverServices() is set to false, to register only hand-picked services into the registry.

Even when service discovery is used, this can be used to add service descriptors that are not part of a service discovery mechanism (such as testing services).

Specified by:

serviceDescriptors in interface ServiceRegistryConfig

Returns:

services to register

serviceInstances

public Map<ServiceDescriptor<?>,Object> serviceInstances()

Description copied from interface: ServiceRegistryConfig

Manually register initial bindings for some of the services in the registry.

Specified by:

serviceInstances in interface ServiceRegistryConfig

Returns:

service instances to register

lookupCacheEnabled

public boolean lookupCacheEnabled()

Description copied from interface: ServiceRegistryConfig

Flag indicating whether service lookups (i.e., via ServiceRegistry.first(io.helidon.service.registry.Lookup)) are cached.

Specified by:

lookupCacheEnabled in interface ServiceRegistryConfig

Returns:

the flag indicating whether service lookups are cached, defaults to false

lookupCacheSize

public int lookupCacheSize()

Description copied from interface: ServiceRegistryConfig

Size of the lookup cache when ServiceRegistryConfig.lookupCacheEnabled() is set to true.

Specified by:

lookupCacheSize in interface ServiceRegistryConfig

Returns:

cache size

interceptionEnabled

public boolean interceptionEnabled()

Description copied from interface: ServiceRegistryConfig

Flag indicating whether runtime interception is enabled. If set to false, methods will be invoked without any interceptors, even if interceptors are available.

Specified by:

interceptionEnabled in interface ServiceRegistryConfig

Returns:

whether to intercept calls at runtime, defaults to true

limitActivationPhase

public ActivationPhase limitActivationPhase()

Description copied from interface: ServiceRegistryConfig

In certain conditions Injection services should be initialized but not started (i.e., avoiding calls to PostConstruct etc.). This can be used in special cases where the normal Injection startup should limit lifecycle up to a given phase.

Specified by:

limitActivationPhase in interface ServiceRegistryConfig

Returns:

the phase to stop at during lifecycle

useBinding

public boolean useBinding()

Description copied from interface: ServiceRegistryConfig

Flag indicating whether compile-time generated Binding's should be used at initialization when starting the registry using ServiceRegistryManager.start(Binding).

This option is ignored when starting the service registry in any other way.

Specified by:

useBinding in interface ServiceRegistryConfig

Returns:

the flag indicating whether the provider is permitted to use binding generated code from compile-time, defaults to true

• Binding

maxRunLevel

public double maxRunLevel()

Description copied from interface: ServiceRegistryConfig

Maximal run level to handle when starting from ServiceRegistryManager.start(Binding). This setting is ignored when starting registry using other means, as run levels are not handled by default.

Specified by:

maxRunLevel in interface ServiceRegistryConfig

Returns:

maximal run level to lookup during application startup when using generated binding

runLevels

public List<Double> runLevels()

Description copied from interface: ServiceRegistryConfig

Run levels that should be initialized at startup. Generated Binding will configure all declared run levels of services in the application.

Note that the result WILL be ordered before use, so initialization will always be handled from the smallest run level to the highest.

Specified by:

runLevels in interface ServiceRegistryConfig

Returns:

run levels to initialize, up to ServiceRegistryConfig.maxRunLevel(), only used when starting the registry through ServiceRegistryManager.start(Binding) or ServiceRegistryManager.start(Binding, ServiceRegistryConfig)

toString

Overrides:

toString in class Object

equals

public boolean equals(Object o)

Overrides:

equals in class Object
