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
