Then completely refactoring the class into a fluent API came into my mind. So we can write validations like this:\n\n``` java\nvalidator.param.inOrder().required().type(STRING).optional().type(INTEGER).validate(isValid);\n\nvalidator.param.anyOrder().required().extends(VIEW).optional().type(BOOLEAN).validate(isValid);\n```\n\nI think this covers any possibilities, and with this all pamater validation can be handled by calling one method chain (for example an additional `zeroOrOneParameter()` call is not needed).\n","author":{"url":"https://github.com/WonderCsabo","@type":"Person","name":"WonderCsabo"},"datePublished":"2014-12-23T10:33:55.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":3},"url":"https://github.com/1284/androidannotations/issues/1284"}
