Class ServiceFactory

java.lang.Object

com.pingidentity.pa.sdk.services.ServiceFactory

public final class ServiceFactory
extends Object

This class is used to discover and cache interface instances. The cache is static and grows as it is used to discover new instances.

Method Detail

getImplClasses

public static <T> List<Class<?>> getImplClasses(Class<T> clazz)

Acquires the list of implementation classes when multiple classes may be provided.

Type Parameters:

T - The interface type.

Parameters:

clazz - The class representing the interface for which to look for registered implementations.

Returns:

The list of types provided. Ordering is based on classloader behavior and should not be depended upon. (never null)

getSingleImpl

public static <T> T getSingleImpl(Class<T> clazz)

Acquires the implementation when one and only one implementation is expected. Provides an instance if the first instance encountered is instantiable. Logs warnings if there are more than 1 impls available. Returned impl type is based upon classloader behavior and may be non-deterministic.

Type Parameters:

T - The interface type.

Parameters:

clazz - The class representing the Interface for which to look for registered implementations.

Returns:

A instance of the impl created using the no-argument constructor.

Throws:

RuntimeException - when errors are encountered.

getImplInstances

public static <T> List<T> getImplInstances(Class<T> clazz)

Acquires the list of the implementation instances when multiple instances may be provided.

Type Parameters:

T - The interface type.

Parameters:

clazz - The class representing the Interface for which to look for registered implementations.

Returns:

A list of discovered instances of the instantiated type specified. Ordering is based on classloader behavior and should not be depended upon. Values are

isValidImplName

public static <T> boolean isValidImplName(Class<T> spiClazz,
                                          String classname)

Checks whether the given classname is a valid implementation of the SPI class.

Type Parameters:

T - The interface type.

Parameters:

spiClazz - The SPI class to be checked against.

classname - The classname to be validated.

Returns:

true if the given classname is a valid implementation of the SPI class.

bodyFactory

public static BodyFactory bodyFactory()

Helper method to provide an implementation of BodyFactory.

Returns:

an implementation of HeadersFactory.

headersFactory

public static HeadersFactory headersFactory()

Helper method to provide an implementation of HeadersFactory.

Returns:

an implementation of HeadersFactory.

configurationModelAccessorFactory

public static ConfigurationModelAccessorFactory configurationModelAccessorFactory()

Helper method to provide an implementation of ConfigurationModelAccessorFactory

Returns:

an implementation of ConfigurationModelAccessorFactory
