Constructors

Modifier	Constructor and Description
protected	ConfigFactory(SubjectFactory<S> subjectFactory, Class<C> configClass, String configKey) Creates a new configuration factory for the specified class of subjects capable of generating the configurations of the specified class.
protected	ConfigFactory(SubjectFactory<S> subjectFactory, Class<C> configClass, String configKey, boolean isList) Creates a new configuration factory for the specified class of subjects capable of generating the configurations of the specified class.

Method Summary

Modifier and Type	Method and Description
Class<C>	configClass() Returns the class of the configuration which this factory generates.
String	configKey() Returns the unique key (within subject class) of this configuration.
abstract C	createConfig() Creates a new but uninitialized configuration.
boolean	isList() Indicates whether the configuration is a list and should be backed by a JSON array rather than JSON object.

Constructor Detail

ConfigFactory

protected ConfigFactory(SubjectFactory<S> subjectFactory,
                        Class<C> configClass,
                        String configKey)

Creates a new configuration factory for the specified class of subjects capable of generating the configurations of the specified class. The subject and configuration class keys are used merely as keys for use in composite JSON trees.

Parameters:

subjectFactory - subject factory

configClass - configuration class

configKey - configuration class key

ConfigFactory

protected ConfigFactory(SubjectFactory<S> subjectFactory,
                        Class<C> configClass,
                        String configKey,
                        boolean isList)

Creates a new configuration factory for the specified class of subjects capable of generating the configurations of the specified class. The subject and configuration class keys are used merely as keys for use in composite JSON trees.

Note that configurations backed by JSON array are not easily extensible at the top-level as they are inherently limited to holding an ordered list of items.

Parameters:

subjectFactory - subject factory

configClass - configuration class

configKey - configuration class key

isList - true to indicate backing by JSON array

Method Detail

subjectFactory

public SubjectFactory<S> subjectFactory()

Returns the class of the subject to which this factory applies.

Returns:

subject type

configClass

public Class<C> configClass()

Returns the class of the configuration which this factory generates.

Returns:

configuration type

configKey

public String configKey()

Returns the unique key (within subject class) of this configuration. This is primarily aimed for use in composite JSON trees in external representations and has no bearing on the internal behaviours.

Returns:

configuration key

createConfig

public abstract C createConfig()

Creates a new but uninitialized configuration. Framework will initialize the configuration via Config.init(S, java.lang.String, com.fasterxml.jackson.databind.JsonNode, com.fasterxml.jackson.databind.ObjectMapper, org.onosproject.net.config.ConfigApplyDelegate) method.

Returns:

new uninitialized configuration

isList

public boolean isList()

Indicates whether the configuration is a list and should be backed by a JSON array rather than JSON object.

Returns:

true if backed by JSON array
