public class LibraryAE
extends MemorySymEnv

An SymEnv backed by a random-access library. It can operate in two modes: 1) "observe" - keep track of bindings from which to later create a library 2) "retrieve" - access bindings in a library

LibraryAE

public LibraryAE()

Method Detail

getParent

public SymbolicEnvironment getParent()

Specified by:

getParent in interface SymbolicEnvironment

Overrides:

getParent in class MemorySymEnv

addSymbolicBindings

public void addSymbolicBindings(Library lib,
                       Pair s)

addBinding

public void addBinding(Library lib,
              Symbol sym,
              int ep)

undefine

public void undefine(Symbol s)

Specified by:

undefine in interface SymbolicEnvironment

Overrides:

undefine in class MemorySymEnv

getLoc

public int getLoc(Symbol s)

Specified by:

getLoc in interface SymbolicEnvironment

Overrides:

getLoc in class MemorySymEnv

store

public int store(Symbol s,
        Value v)

Catch all occurences of sets and note them for when we serialize

Overrides:

store in class MemorySymEnv

Parameters:

s - the key being set

v - the value associated with the key

Returns:

index of binding

deserialize

public void deserialize(Deserializer d)
                 throws java.io.IOException

Description copied from class: Expression

All Expressions must implement a default (no-argument) constructor. Those that wish to b serialized to a heap must implement both this and the serialize method. The Expression may use any method of the DataInput stream and the Deserializer serialization context to read its state.

Specified by:

deserialize in interface SymbolicEnvironment

Overrides:

deserialize in class MemorySymEnv

Parameters:

d - the Deserializer

Throws:

java.io.IOException

serialize

public void serialize(Serializer s)
               throws java.io.IOException

Description copied from class: Expression

All Expressions must implement a default (no-argument) constructor. Those that wish to be serialized to a heap must implement both this and the deserialize method. The Expression may use any method of the Serializer, which implements java.io.DataOutput to write its state.

Specified by:

serialize in interface SymbolicEnvironment

Overrides:

serialize in class MemorySymEnv

Parameters:

s - the Serializer

Throws:

java.io.IOException

visit

public boolean visit(ExpressionVisitor v)

Specified by:

visit in interface ExpressionVisitee

Overrides:

visit in class MemorySymEnv
