Example 7 with DriverExecutionProfile

use of com.datastax.oss.driver.api.core.config.DriverExecutionProfile in project java-driver by datastax.

the class Reflection method buildFromConfigProfiles.

/**
 * Tries to create multiple instances of a class, given options defined in the driver
 * configuration and possibly overridden in profiles.
 *
 * <p>For example:
 *
 * <pre>
 * my-policy.class = package1.PolicyImpl1
 * profiles {
 *   my-profile { my-policy.class = package2.PolicyImpl2 }
 * }
 * </pre>
 *
 * The class will be instantiated via reflection, it must have a constructor that takes two
 * arguments: the {@link DriverContext}, and a string representing the profile name.
 *
 * <p>This method assumes the policy is mandatory, the class option must be present at least for
 * the default profile.
 *
 * @param context the driver context.
 * @param classNameOption the option that indicates the class (my-policy.class in the example
 *     above).
 * @param rootOption the root of the section containing the policy's configuration (my-policy in
 *     the example above). Profiles that have the same contents under that section will share the
 *     same policy instance.
 * @param expectedSuperType a super-type that the class is expected to implement/extend.
 * @param defaultPackages the default packages to prepend to the class name if it's not qualified.
 *     They will be tried in order, the first one that matches an existing class will be used.
 * @return the policy instances by profile name. If multiple profiles share the same
 *     configuration, a single instance will be shared by all their entries.
