You can define a <dfn title="A regular expression, regex or regexp is a sequence of characters that define a search pattern for strings.">regular expression</dfn> `pattern` that the parameter should match:

This specific regular expression pattern checks that the received parameter value:

### Atualizar um Hero com `HeroUpdate` { #update-a-hero-with-heroupdate }

Podemos **atualizar um hero**. Para isso, usamos uma operação HTTP `PATCH`.
