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).
