public function Uuid::isValid

Checks that a string appears to be in the format of a UUID.

Plugins should not implement validation, since UUIDs should be in a consistent format across all plugins.

Parameters

string $uuid: The string to test.

Return value

bool TRUE if the string is well formed, FALSE otherwise.
