Method Details

findProvider

public static Provider findProvider(Supplier<Provider[]> providerSupplier,
 String providerName,
 Class<?> serviceType,
 String algorithm)

Find the first provider from the supplier which provides the given service type and algorithm name. The simple name of the service type class is used to identify the service. If a providerName is specified the match will only be tested against providers with the name specified.

Parameters:

providerSupplier - the provider supplier (must not be null)

providerName - the name of the provider, can be null

serviceType - the service type as a class name (must not be null)

algorithm - the algorithm name (must not be null)

Returns:

the provider, or null if none is found

findProvider

public static Provider findProvider(Provider[] providers,
 String providerName,
 Class<?> serviceType,
 String algorithm)

Find the first provider from the supplier which provides the given service type and algorithm name. The simple name of the service type class is used to identify the service. If a providerName is specified the match will only be tested against providers with the name specified.

Parameters:

providers - the providers to searchr (must not be null)

providerName - the name of the provider, can be null

serviceType - the service type as a class name (must not be null)

algorithm - the algorithm name (must not be null)

Returns:

the provider, or null if none is found

findProvider
