Constructor Detail

Record

public Record()

Record

public Record(Value type,
              int sz)

Method Detail

getType

public Value getType()

setType

public void setType(Value v)

getSlot

public Value getSlot(int idx)

setSlot

public void setSlot(int idx,
                    Value v)

size

public int size()

valueEqual

public boolean valueEqual(Value v)

Description copied from class: Value

Compares this value to another for semantic equality. Used to implement Scheme's 'equal?'. Subclasses must test for pointer equality as well as semantic equality, so that infinite loops on recursive structures are less likely.

Overrides:

valueEqual in class Value

Parameters:

v - the other Value

valueHashCode

public int valueHashCode()

Description copied from class: Value

a hashCode function consistent with valueEqual

Overrides:

valueHashCode in class Value

Returns:

hash code

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

display

public void display(ValueWriter w)
             throws java.io.IOException

Specified by:

display in class Value

Throws:

java.io.IOException
