Method Detail

getSettings

public Map getSettings()

Description copied from interface: ConfigurationService

Access to the complete map of config settings. The returned map is immutable

Specified by:

getSettings in interface ConfigurationService

Returns:

The immutable map of config settings.

injectServices

public void injectServices(ServiceRegistryImplementor serviceRegistry)

Description copied from interface: ServiceRegistryAwareService

Callback to inject the registry.

Specified by:

injectServices in interface ServiceRegistryAwareService

Parameters:

serviceRegistry - The registry

getSetting

public <T> T getSetting(String name,
                        ConfigurationService.Converter<T> converter)

Description copied from interface: ConfigurationService

Get the named setting, using the specified converter.

Specified by:

getSetting in interface ConfigurationService

Type Parameters:

T - The Java type of the conversion

Parameters:

name - The name of the setting to get.

converter - The converter to apply

Returns:

The converted (typed) setting. May return null (see ConfigurationService.getSetting(String, Class, Object))

getSetting

public <T> T getSetting(String name,
                        ConfigurationService.Converter<T> converter,
                        T defaultValue)

Description copied from interface: ConfigurationService

Get the named setting, using the specified converter and default value.

Specified by:

getSetting in interface ConfigurationService

Type Parameters:

T - The Java type of the conversion

Parameters:

name - The name of the setting to get.

converter - The converter to apply

defaultValue - If no setting with that name is found, return this default value as the result.

Returns:

The converted (typed) setting. Will be the defaultValue if no such setting was defined.

getSetting

public <T> T getSetting(String name,
                        Class<T> expected,
                        T defaultValue)

Description copied from interface: ConfigurationService

Get the named setting. Differs from the form taking a Converter in that here we expect to have a simple cast rather than any involved conversion.

Specified by:

getSetting in interface ConfigurationService

Type Parameters:

T - The Java type of the conversion

Parameters:

name - The name of the setting to get.

expected - The expected Java type.

defaultValue - If no setting with that name is found, return this default value as the result.

Returns:

The converted (typed) setting. Will be the defaultValue if no such setting was defined.

cast

public <T> T cast(Class<T> expected,
                  Object candidate)

Description copied from interface: ConfigurationService

Cast candidate to the instance of expected type.

Specified by:

cast in interface ConfigurationService

Type Parameters:

T - The java type of the expected return

Parameters:

expected - The type of instance expected to return.
