Class Struct.ArrayMember

java.lang.Object
  com.dautelle.util.Struct.Member
      com.dautelle.util.Struct.ArrayMember

Enclosing class:

Struct

public final class Struct.ArrayMember

extends Struct.Member

This class represents an array member. Array's element can be Struct.Member or Struct/Union. For example the following C code:

     struct Vertex {
         float x;
         float y;
     };
     struct Rectangle {
         int    colors[4];
         struct Vertex vertices[2][2];
         char   text[4][20];
     };

would be represented by:

     public class Vertex extends Struct {
         public final Float32 x = new Float32();
         public final Float32 y = new Float32();
     }
     public class Rectangle extends Struct {
         public final Signed32[] colors = (Signed32[]) new ArrayMember(Signed32.class, 4).get();
         public final Vertex[][] vertices = (Vertex[][]) new ArrayMember(Vertex.class, new int[] {2, 2}).get();
         public final UTF8String20[] text = (UTF8String20[]) new ArrayMember(UTF8String20.class, 4).get();
         public class UTF8String20 extends UTF8String {
             public UTF8String20() { // Default constructor (no argument) to be used.
                 super(20); // UTF8String of 20 bytes.
             }
         }
     }

Arrays elements are directly accessible:

     float x01 = myRectangle.vertices[0][1].x.get();
     myRectangle.colors[2].set(0xFF00FF);
     myRectangle.text[0].set("Blah, Blah, Blah");

Parameters:

componentType - the component type of the array.

dimensions - the dimensions of the array.

Throws:

java.lang.ClassCastException - if the componentType is not derived from Struct.Member or Struct.
