Examples with Command com.google.refine.commands.Command used on opensource projects

Example 1 with Command

use of com.google.refine.commands.Command in project OpenRefine by OpenRefine.

the class PreviewWikibaseSchemaCommand method doPost.

/**
 * This command uses POST but is left CSRF-unprotected since it does not
 * incur a side effect or state change in the backend.
 * The reason why it uses POST is to make sure large schemas and engines
 * can be passed as parameters.
