ReturnAddress

java.lang.Object

public final class ReturnAddress extends Object implements com.android.dx.rop.type.TypeBearer

Representation of a subroutine return address. In Java verification, somewhat counterintuitively, the salient bit of information you need to know about a return address is the start address of the subroutine being returned from, not the address being returned to, so that's what instances of this class hang onto.

Fields Summary
private final int
subroutineAddress
{@code >= 0;} the start address of the subroutine being returned from
Constructors Summary
public ReturnAddress(int subroutineAddress)
Constructs an instance.
param
subroutineAddress {@code >= 0;} the start address of the subroutine being returned from
if (subroutineAddress < 0) { throw new IllegalArgumentException("subroutineAddress < 0"); } this.subroutineAddress = subroutineAddress;
