        Parameters:
        component - target component

    • Method Detail

      • setValue

         void setValue(String value)

        Set the given value for the component, as the user would type it.

        A value that only breaks a validation constraint — shorter than minLength, not matching pattern, or the empty value on a required field — is committed all the same, because the browser commits it too and simply leaves the field invalid. Assert that outcome with isInvalid instead of expecting this method to throw. A value the user physically cannot type is refused: the browser truncates what is over maxLength and filters out the keystrokes allowedCharPattern does not match, so a longer value or a disallowed character fails with an IllegalArgumentException. So does null, as a text area has no null state — emptying the field is clear.
        Parameters:
        value - value to set

      • clear

         void clear()

        Empties the field, as when the user deletes its contents (or clicks the clear button, where one is shown).

        Emptying is something the user can always do, so it needs no clear button: a field may legitimately end up invalid — a required field, for instance — once emptied.

      • clickClearButton

         void clickClearButton()

        Empties the field by clicking its clear button, as the user would.

        Unlike clear, which models selecting the contents and deleting them and is therefore always available, this requires the clear button to be visible — a hidden clear button is not something the user can click.
