Package ru.vyarus.dropwizard.guice.debug.hook

Class GuiceProvisionTimeHook

java.lang.Object

ru.vyarus.dropwizard.guice.debug.hook.GuiceProvisionTimeHook

All Implemented Interfaces:

GuiceyConfigurationHook

public class GuiceProvisionTimeHook
extends Object
implements GuiceyConfigurationHook

Hook enables guice provision time logs. It is assumed to be used to enable provision time logs for compiled application with system property: -Dguicey.hooks=provision-time.

Also, hook could be used in tests to track created guice beans:

   @EnableHook
    static GuiceProvisionTimeHook hook = new GuiceProvisionTimeHook();

   @Test
    public void test() {
        hook.clearData()
        // anything requiring provision
        injector.getInstance(SomeService.class);
        // the report would contain only one bean creation
        System.out.println(hook.renderReport())
    }

Method Details

configure

public void configure(GuiceBundle.Builder builder)

Description copied from interface: GuiceyConfigurationHook

Configuration is applied just after manual configuration (through bundle's builder in application class).

GuiceBundle.Builder contains special methods for test support:

• Generic disable: GuiceBundle.Builder.disable(java.util.function.Predicate[])
• Direct disable* method, for example GuiceBundle.Builder.disableExtensions(Class[])
• Guice bindings override: GuiceBundle.Builder.modulesOverride(com.google.inject.Module...)

All other configuration options are also available, so it is possible to register extra extensions, bundles etc. or modify guicey options (GuiceBundle.Builder.option(Enum, Object)).

All configuration items, registered with hook will be scoped as GuiceyConfigurationHook instead of Application and so will be clearly distinguishable in configuration logs (GuiceBundle.Builder.printDiagnosticInfo()).

Specified by:

configure in interface GuiceyConfigurationHook

Parameters:

builder - just created bundle's builder

clearData

public void clearData()

Clear collected data.

getRecordedData

public com.google.common.collect.ListMultimap<com.google.inject.Binding<?>,Duration> getRecordedData()

Map format: binding - provisions time.

Returns:

recorded provision data

renderReport

public String renderReport()

Returns:

render beans creation report from collected data
