All Implemented Interfaces:

Visitor

public class SimpleStackSimulator

extends java.lang.Object

implements Visitor

Builds a picture of the actionscript stack layout as each instruction is executed, driving an implementation of StackListener.

For example, when a NOT action is encountered, we pop an Operand off our emulated stack, create a new Operand to hold the result, and then pass these values to StackListener.visitNOT(Action,Operand,Operand). The result-Operand's value isn't calculated, though the StackListener implementation may fill this in. When visitNot() returns, the SimpleStackSimulator pushes the result Operand onto the stack.

The only time that this class fills in the value for Operands is where constant values are pushed onto the stack. Without this, we wouldn't be able to resonably emulate things like function-calls, where the number of values to pop off the stack is determined by the (usually constant) value on the top of the stack.

Since no attempt is made to follow the branches in the flow of control produced by BranchAction subclasses, encountering any Action that is a branch, or that is the target of a branch invalidates all our guesses about the stack layout. Later attempts to read from this invalid part of the stack will always produce Operands with unknown values.

Field Detail

stack

protected StackInfo stack

currentLookupTable

protected LookupTable currentLookupTable

Constructor Detail

SimpleStackSimulator

public SimpleStackSimulator(StackListener listener)

Method Detail

push

protected void push(Operand entry)

convenience method; calls stack.push(entry)

pop

protected Operand pop()

convenience method; calls stack.pop()

invalidateState

protected void invalidateState()

popArgs

protected java.util.List popArgs()

pops a list of arguments off the stack ant returns the Operand objects in a List. The number of arguments is expected as the value on the top of the stack; after the argument count is poped, the number of values indicated are poped and added to the result List. If the arguemnt count is 0, this mathod will return null, rather than an empty List.

visitHandle

public void visitHandle(ActionHandle handle)
                 throws JASVisitorException

Description copied from interface: Visitor

the handle of a Action is always visited before the Action itself. (The implementation of visitHandle() doesn't have to visit the Action referenced by the handle, this is done elsewhere.)
