Interface ConfigurationService

All Superinterfaces:

Serializable, Service

public interface ConfigurationService
extends Service

Provides access to the initial user-provided configuration values. Generally speaking these values come from:

• Calls to StandardServiceRegistryBuilder.loadProperties(java.lang.String)
• Calls to StandardServiceRegistryBuilder.applySetting(java.lang.String, java.lang.Object)
• Calls to StandardServiceRegistryBuilder.applySettings(java.util.Map)
• Calls to StandardServiceRegistryBuilder.configure()

Method Detail

getSettings

Map getSettings()

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

Returns:

The immutable map of config settings.

getSetting

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

Get the named setting, using the specified converter.

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 getSetting(String, Class, Object))

getSetting

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

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

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

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

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.

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

@Deprecated
<T> T cast(Class<T> expected,
           Object candidate)

Deprecated.

No idea why this is exposed here...

Cast candidate to the instance of expected type.

Type Parameters:

T - The java type of the expected return

Parameters:

expected - The type of instance expected to return.

candidate - The candidate object to be casted.

Returns:

The instance of expected type or null if this cast fail.
