Load reference from local variable
Format
aload_
Forms
aload_0 = 24 (0x18) aload_1 = 25 (0x19) aload_2 = 26 (0x1a) aload_3 = 27 (0x1b)
Stack
… → …, objectref
Description
The must be a valid index into the local variables of the current frame ( Section 3.5, Frames). The local variable at must contain a reference. The objectref in the local variable at is pushed onto the operand stack.
Notes
An aload_ instruction cannot be used to load a value of type returnAddress from a local variable onto the operand stack. This asymmetry with the corresponding astore_ instruction is intentional.
Each of the aload_ instructions is the same as aload with an index of , except that the operand is implicit.
