laload : retrieve long integer from array : index : visitInsn()

Description

Retrieves a long integer from a long integer array and places it on the stack. arrayref is a reference to an array of long integers. index is an int. The arrayref and index are removed from the stack, and the long integer entry at the given index in the array is pushed onto the stack.

Example

; This is like the Java code:
;     long x = arr[0];
; where x is local variable 2 and arr is an array of longs in local variable 1
aload_1       ; load local variable 1 onto the stack
iconst_0      ; push the integer 0 onto the stack
laload        ; retrieve the entry
lstore_2      ; store the entry in local variables 2 and 3

Exceptions

NullPointerException - arrayref is null

ArrayIndexOutOfBoundsException - index is < 0 or >= arrayref.length

Notes

Array indices start at 0 (the first entry in the array is at index 0).
