Example 6 with Transaction

use of org.apache.activemq.artemis.core.transaction.Transaction in project activemq-artemis by apache.

the class PageCursorProviderImpl method onPageModeCleared.

/**
 * Delete everything associated with any queue on this address.
 * This is to be called when the address is about to be released from paging.
 * Hence the PagingStore will be holding a write lock, meaning no messages are going to be paged at this time.
 * So, we shouldn't lock anything after this method, to avoid dead locks between the writeLock and any synchronization with the CursorProvider.
