@@ -49,23 +49,21 @@ To represent attributes, we must map Java values to [XPath Data Model (XDM)](htt
values. In the following table we refer to the type conversion function as `conv`, a function from Java types
to XDM types.
| Java type `T` | XSD type `conv(T)` |
|---------------|---------------------------------------|
| `int` | `xs:integer` |
| `long` | `xs:integer` |
| `double` | `xs:decimal` |
| `float` | `xs:decimal` |
| `boolean` | `xs:boolean` |
| `String` | `xs:string` |
| `Character` | `xs:string` |
| `Enum<E>` | `xs:string` (uses `Object::toString`) |
| `List<E>` | `conv(E)*` (a sequence type) |
| Java type `T` | XSD type `conv(T)` |
|-------------------|---------------------------------------|
| `int` | `xs:integer` |
| `long` | `xs:integer` |
| `double` | `xs:decimal` |
| `float` | `xs:decimal` |
| `boolean` | `xs:boolean` |
| `String` | `xs:string` |
| `Character` | `xs:string` |
| `Enum<E>` | `xs:string` (uses `Object::toString`) |
| `Collection<E>` | `conv(E)*` (a sequence type) |
The same `conv` function is used to translate rule property values to XDM values.
{% include warning.html content="Lists are only supported for rule properties, not attributes." %}
Additionaly, PMD's own `net.sourceforge.pmd.lang.document.Chars` is also translated to a `xs:string`
