saload : retrieve short from array : index : visitInsn()

Description

Retrieves a short from an array of shorts and places it on the stack. arrayref is a reference to an array of shorts. index is an int. The arrayref and index are removed from the stack, and the 16-bit signed short at the given index in the array is retrieved, sign-extended to an int, and pushed onto the stack.

Example

; This is like the Java code:
;      short x = arr[0];
; where x is local variable 2 and arr is
; an array in local variable 1
aload_1       ; load local variable 1 onto the stack
iconst_0      ; push the integer 0 onto the stack
saload        ; retrieve the entry
istore_2      ; store the entry in local variable 2

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).
