Examples of speculoos.spi.Source

speculoos.spi.Source
An interface that is implemented by data sources provider and used by mappers managers. A source is responsible for the management of resources associated with a mapper such that connections, credentials, sessions, caches, ... To allow proper life-cycle handling, methods {@link #start(java.util.Map)} and {@link #stop()}are provided:
- Method start is called by the manager of the Source object when it is itself started. This method is passed an environment which is a map from strings to objects. The Source may do what it wants with the map itself but must not modify the objects stored inside.
- Method stop is called by the manager of the Source object when is stopped.
- Method create is called when a client of the manager wants to retrieve a mapper object associated with this source, giving the opportunity to the source object to prepare resources for the mapper
- Method release is called when the client no longer needs the mapper.
