Example 1 with CustomConfigResolver

use of com.emc.storageos.customconfigcontroller.CustomConfigResolver in project coprhd-controller by CoprHD.

the class CustomConfigHandler method getCustomConfigPreviewValue.

/**
 * Uses the samples provided in the configuration item to generate a resolved
 * name for a given mask, configuration and scope. This can be used to preview
 * and validate a name mask prior to setting it.
 *
 * @param name the configuration type name
 * @param value the name mask to be resolved.
 * @param scope the scope to be used to for deciding which constraints to apply.
 * @param variables a map of variable-name-to-variable-value. This map can contain
 *            a value for all or only some of the name mask variables, or it can be
 *            empty. Any missing variable will be replaced with the variable default.
 * @return the resolved name.
 * @throws CustomConfigControllerException for invalid input.
