Usage

From source file:io.springagora.store.rest.controllers.ProductRestController.java

/**
 * Internal helper method that correctly applies pagination rules for list
 * operations that support it. It won't throw any error in case of errors 
 * during the parse of the page and size directives. Instead it will always
 * assume default values.//from www . j a v a2s  . c o  m
 * <p>
 * Once processed, pagination variables are sent to {@code IPaginatedFinder}
 * implementation received by the method, that can effectivelly fetch the page.
 * 
 * @param page      {@code String}. Current page being requested.
 * @param size      {@code String}. Ammount of elements being fetched.
 * @param finder    {@code IPaginatedFinder}. Finder to be executed. 
 * 
 * @return
 *      A {@code Page} with all results for a given page, in a given range. 
 *      If problems ocurred during the conversion of page and size, it will
 *      attempt to fetch the first page, with 10 results.
 *      
 * @throws EntityNotFoundException
 *      To be compliant with the RESTful API, if no results are found for a 
 *      given operation and page, then it will throw this exception that is
 *      correctly converted to an API error by the framework.
