40 * {@code Expression} subinterface for array initializers. The array
41 * initialization expression has a few interesting features. Notice, the
42 * argument is {@code Object}. The contract is that the {@code Object} must be
43 * of runtime-type {@code Expression} or, more likely, {@code Object[]}. If the
44 * type is {@code Object[]}, then each element of that array will recursively be
45 * introspected, checking again to see if the type is {@code Expression} or
46 * {@code Object[]}. In this manner, one can arbitrarily nest expressions. This
47 * is the only way I know how to accomplish this behavior (ie not knowing the
48 * dimensionality of an argument at compile-time).
49 * <P>
50 * For example, say we wanted to make the array: {@code int[][] aai = 1, 2}, {
51 * 3, 4 }}; } One could do this by:
52 *
53 * <PRE>
54 * Expression[] a1 = new Expression[2];
55 * a1[0] = new IntLiteralImpl(1);
56 * a1[1] = new IntLiteralImpl(2);
57 * Expression[] a2 = new Expression[2];
58 * a2[0] = new IntLiteralImpl(3);
59 * a2[1] = new IntLiteralImpl(4);
60 * Object[] a3 = new Object[2];
61 * a3[0] = a1;
62 * a3[1] = a2;
63 * ArrayDeclarationStatement asd = new ArrayDeclarationStatementImpl(); // fictional
64 * // implementation
65 * asd.setInitialization(a3);
66 * </PRE>
