Class AssignArrayValueAppender

java.lang.Object

org.nd4j.bytebuddy.arrays.assign.AssignArrayValueAppender

All Implemented Interfaces:

net.bytebuddy.implementation.bytecode.ByteCodeAppender

public class AssignArrayValueAppender
extends Object
implements net.bytebuddy.implementation.bytecode.ByteCodeAppender

Handles loading the proper index To assign an element to an array the byte code looks like the following: public static void main(java.lang.String[]); Code: 0: invokestatic #2 // Method returnArr:()[I <- this is our reference 3: astore_1 //store the variable in 1 4: aload_1 //load the actual variable 1 5: iconst_0 push a 0 on the stack (now we're here asking for the index of the array based on the given variable 6: iconst_5 //push a 5 on to the stack (this is the value we want to assign in the array) 7: iastore //do the actual store operation, we don't do this here 8: return } This is intended to be used with the following method signature: void(int[] arr,int index,int value)
