Closure

public Closure(boolean arity,
               int fcount,
               Expression body,
               Value[] env,

public Closure()
Method Detail

apply

public void apply(Interpreter r)
           throws ContinuationException
Description copied from class: Procedure
Called when applying this procedure to a number of arguments in the Interpreter's vlr register. The code can return a value by setting the Interpreter's acc register and/or cause additional expressions to be evaluated by setting the Interpreter's nxp register.

Specified by:
apply in class Procedure
Parameters:
r - the Interpreter
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

express

public Value express()
Description copied from class: Expression
A debugging function, express returns a Scheme value that describes this expression. See examples in sisc.exprs.*

Overrides:
express in class Value

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
