de.iip_ecosphere.platform.connectors.DefaultConnectorFactoryDescriptor.ProtocolAdapterSupplier<O,I,CO,CI>

de.iip_ecosphere.platform.connectors.DefaultConnectorFactoryDescriptor.SingleProtocolAdapterSupplier<O,I,CO,CI>

Type Parameters:

O - the output type from the underlying machine/platform

I - the input type to the underlying machine/platform

CO - the output type of the connector

CI - the input type of the connector

Enclosing class:

DefaultConnectorFactoryDescriptor

protected static class DefaultConnectorFactoryDescriptor.SingleProtocolAdapterSupplier<O,I,CO,CI>
extends DefaultConnectorFactoryDescriptor.ProtocolAdapterSupplier<O,I,CO,CI>

Type-safe protocol adapter supplier for multiple adapters. Doesn't work without as Java does not allow casting from/to a supplier with inner wildcard type parameters.
