public class ThreadObjectManager

extends java.lang.Object

Provides static methods for managing key/value pairs that are bound to the current thread. Supports one thread value per key without overwriting, i.e. a value needs to be removed before a new one can be set for the same key.

Used by DataSourceTransactionManager to keep a JDBC transaction per DataSource and thread. Does not need to be used by application developers.
