Examples of org.datanucleus.store.rdbms.datasource.dbcp.pool.ObjectPool.borrowObject()

org.datanucleus.store.rdbms.datasource.dbcp.pool.ObjectPool.borrowObject()

Obtains an instance from this pool.

Instances returned from this method will have been either newly created with {@link PoolableObjectFactory#makeObject makeObject} or will be a previously idle object andhave been activated with {@link PoolableObjectFactory#activateObject activateObject} andthen validated with {@link PoolableObjectFactory#validateObject validateObject}.

By contract, clients must return the borrowed instance using {@link #returnObject returnObject}, {@link #invalidateObject invalidateObject}, or a related method as defined in an implementation or sub-interface.

The behaviour of this method when the pool has been exhausted is not strictly specified (although it may be specified by implementations). Older versions of this method would return null to indicate exhaustion, newer versions are encouraged to throw a {@link NoSuchElementException}.

@return an instance from this pool. @throws IllegalStateException after {@link #close close} has been called on this pool. @throws Exception when {@link PoolableObjectFactory#makeObject makeObject} throws an exception. @throws NoSuchElementException when the pool is exhausted and cannot or will not return another instance.
