-/**
- * Defines property resolution behavior on arrays.
- *
- * <p>This resolver handles base objects that are Java language arrays.
- * It accepts any object as a property and coerces that object into an
- * integer index into the array. The resulting value is the value in the array
- * at that index.</p>
- *
- * <p>This resolver can be constructed in read-only mode, which means that
- * {@link #isReadOnly} will always return <code>true</code> and
- * {@link #setValue} will always throw
- * <code>PropertyNotWritableException</code>.</p>
- *
- * <p><code>ELResolver</code>s are combined together using
- * {@link CompositeELResolver}s, to define rich semantics for evaluating
- * an expression. See the javadocs for {@link ELResolver} for details.</p>
