Field Detail

exp

protected Exp exp

Holds the exp AST of this exp AST value.

Constructor Detail

DefaultExpASTValue

protected DefaultExpASTValue(Exp exp)

Default constructor.

Parameters:

exp - The exp AST for this AST value. Must be non-null.

Method Detail

getExp

public Exp getExp()

Description copied from interface: IExpASTValue

Gets the exp AST of this exp AST value.

Specified by:

getExp in interface IExpASTValue

Returns:

The exp AST of this exp AST value. Non-null.

getReferenceId

public int getReferenceId()

Description copied from interface: INonPrimitiveValue

Gets this non-primitive value reference id.

Specified by:

getReferenceId in interface INonPrimitiveValue

Returns:

This value reference id.

getType

public Type getType()

Description copied from interface: IValue

Gets the type of this value.

Specified by:

getType in interface IValue

Returns:

The type of this value. Non-null.

See Also:

Type.getTypeId()

getTypeId

public int getTypeId()

Description copied from interface: IValue

Gets the type id of this value.

Specified by:

getTypeId in interface IValue

Returns:

The type id of this value.

See Also:

Type.getTypeId()

clone

public IExpASTValue clone(Map<Object,Object> cloneMap)

Description copied from interface: IExpASTValue

Override to specialize return type

Specified by:

clone in interface IExpASTValue

Specified by:

clone in interface INonPrimitiveValue

Specified by:

clone in interface IValue

Parameters:

cloneMap - Original values (IValue) to their clones ( IValue) mapping. The clone map to solve circular references in values. If this value is a key in the map, then this method returns the value of the key in the map. Must be non-null.

Returns:

The clone of this value. Non-null.

dispose

public void dispose()

Description copied from interface: Disposable

Remove references. Once called, avoid using this object.

Specified by:

dispose in interface Disposable

toString

public String toString()

Description copied from interface: IValue

Gets the string representation of this value.

Specified by:

toString in interface IValue

Overrides:

toString in class Object

Returns:

The string representation of this value. Non-null.

validate

public void validate(IBogorConfiguration bc)

Description copied from interface: IValue

Freshen references to Bogor model checking components and other non-serializable objects. Generally, this can be done in a few steps:

Model checking components (IModule implementations) should be reacquired by fetching them from the parameter, bc:

     valueFactory = bc.getValueFactory();
     scheduler = bc.getSchedulingStrategist();
 

Any fields storing Type objects should be treated as stale, but still uniquely identifier by their integer typeId field. This can be used as a key to look up the correct Type instances in the new symbol table's typeId-to-type table:

     typeField = bc.getSymbolTable().getTypeIdTypeTable().get(typeField.getTypeId());
 

Any IValueArray objects contained can simply be "chained" by their IValueArray.validate(IBogorConfiguration) method:

     someValueArray.validate(bc);
 

IValue objects contained directly should not be handled manually by this method; they will be dealt with directly when they are visited later

Specified by:

validate in interface IValue

Parameters:

bc - The Bogor configuration to validate to.

equals

public boolean equals(Object o)

Description copied from interface: IValue

Classes implementing IValue should provide their own equality tests.

Specified by:

equals in interface IValue

Overrides:

equals in class Object

hashCode

public int hashCode()

Description copied from interface: IValue

Classes implementing IValue should provide their own hashing method.

Specified by:

hashCode in interface IValue

Overrides:

hashCode in class Object

compareTo

public int compareTo(IValue o)

Specified by:

compareTo in interface Comparable<IValue>
