the class Heap method open.

Example 7 with OpenConglomerate

use of org.apache.derby.impl.store.access.conglomerate.OpenConglomerate in project derby by apache.

the class Heap method openByContainerKey.

/**
 * Open a heap controller given ContainerKey.
 * <p>
 * Static routine to open a container given input of the ContainerKey.
 * Routine will lock the container first, and then get the Heap from
 * the conglomerate cache.  This insures that interaction with the
 * conglomerate cache is safe with respect to concurrent alter table's
 * which may or may not commit.
 *
 * Currently only package accessible and only used by HeapPostCommit.
 * Longer term would be better to change all of the open interfaces
 * to get lock before accessing conglomerate cache rather than have a
 * specific interface for HeapPostCommit.
 *
 * @see Conglomerate#open
 *
 * @exception  StandardException  Standard exception policy.
