Examples with DataNode org.apache.cayenne.access.DataNode used on opensource projects

Example 1 with DataNode

use of org.apache.cayenne.access.DataNode in project cayenne by apache.

the class ServerRuntime method getDataSource.

/**
 * Provides access to the JDBC DataSource assigned to a given DataNode. A
 * null argument will work if there's only one DataNode configured.
 * <p>
 * Normally Cayenne applications don't need to access DataSource or any
 * other JDBC code directly, however in some unusual conditions it may be
 * needed, and this method provides a shortcut to raw JDBC.

Example 2 with DataNode
