Method Detail

getValue

public Value getValue(Interpreter r)
               throws ContinuationException
Description copied from class: Value
Called to obtain the value of this Value. Simply this.

Specified by:
getValue in interface Immediate
Specified by:
getValue in class Parameter
Parameters:
r - the Interpreter
Returns:
the immediate value of this expression, or null if the value cannot be obtained immediately.
Throws:
ContinuationException

setValue

public void setValue(Interpreter r,
                     Value v)
              throws ContinuationException
Specified by:
setValue in class Parameter
Throws:
ContinuationException

display

public void display(ValueWriter w)
             throws java.io.IOException
Specified by:
display in class Value
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.

Overrides:
serialize in class Expression
Parameters:
s - the Serializer
Throws:
java.io.IOException

deserialize

public void deserialize(Deserializer s)
                 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.

Overrides:
deserialize in class Expression
Parameters:
s - the Deserializer
Throws:
java.io.IOException

visit

public boolean visit(ExpressionVisitor v)
Specified by:
visit in interface ExpressionVisitee
Overrides:
visit in class Expression
