Interface ArrayInitializer

All Superinterfaces:

Codeable, Expression

public interface ArrayInitializer
extends Expression

Expression subinterface for array initializers. The array initialization expression has a few interesting features. Notice, the argument is Object. The contract is that the Object must be of runtime-type Expression or, more likely, Object[]. If the type is Object[], then each element of that array will recursively be introspected, checking again to see if the type is Expression or Object[]. In this manner, one can arbitrarily nest expressions. This is the only way I know how to accomplish this behavior (ie not knowing the dimensionality of an argument at compile-time).

For example, say we wanted to make the array: int[][] aai = 1, 2, { 3, 4 }}; } One could do this by:

 Expression[] a1 = new Expression[2];
 a1[0] = new IntLiteralImpl(1);
 a1[1] = new IntLiteralImpl(2);
 Expression[] a2 = new Expression[2];
 a2[0] = new IntLiteralImpl(3);
 a2[1] = new IntLiteralImpl(4);
 Object[] a3 = new Object[2];
 a3[0] = a1;
 a3[1] = a2;
 ArrayDeclarationStatement asd = new ArrayDeclarationStatementImpl(); // fictional
 // implementation
 asd.setInitialization(a3);
