Method Details

adjustConfigurations

public void adjustConfigurations(List<PropertyFile> configs)

Description copied from interface: GuiceRole

Provides an opportunity, pre-compositing, to influence the configuration sources and order. Configuration sources earlier in this list will be overridden by configuration sources later in the list.

Called before GuiceRole.register(Stage, ClassScannerFactory, GuiceConfig, GuiceSetup, List, AtomicReference, MetricRegistry)

Specified by:

adjustConfigurations in interface GuiceRole

register

public void register(com.google.inject.Stage stage,
 ClassScannerFactory scannerFactory,
 GuiceConfig config,
 GuiceSetup setup,
 List<com.google.inject.Module> modules,
 AtomicReference<com.google.inject.Injector> injectorRef,
 com.codahale.metrics.MetricRegistry metrics)

Description copied from interface: GuiceRole

Provides an opportunity to influence modules (adding, removing, reordering) being loaded. Called before the GuiceSetup class has loaded its modules.

Called before GuiceRole.injectorCreated(Stage, ClassScannerFactory, GuiceConfig, GuiceSetup, List, AtomicReference, MetricRegistry)

Specified by:

register in interface GuiceRole

scannerFactory - a factory for a classpath scanner for the user application classes. Implementations should not hold on to this for long (to save memory usage)

injectorRef - a reference which will be updated to contain the Injector once the guice environment has been set up

metrics - the MetricsRegistry for environment-wide metrics

injectorCreated

public void injectorCreated(com.google.inject.Stage stage,
 ClassScannerFactory scanner,
 GuiceConfig config,
 GuiceSetup setup,
 List<com.google.inject.Module> modules,
 AtomicReference<com.google.inject.Injector> injectorRef,
 com.codahale.metrics.MetricRegistry metrics)

Description copied from interface: GuiceRole

Called once the Injector has been created

Specified by:

injectorCreated in interface GuiceRole

scanner - a factory for a classpath scanner for the user application classes. Implementations should not hold on to this for long (to save memory usage)

modules - the final list of modules in use

injectorRef - the reference to the injector, must contain a non-null value

metrics - the MetricsRegistry for environment-wide metrics
