Method Detail

getEqualsProc

public abstract Procedure getEqualsProc()

getHashProc

public abstract Procedure getHashProc()

get

public abstract Value get(Value k)

put

public abstract Value put(Value k,
                          Value v)

remove

public abstract Value remove(Value k)

size

public abstract int size()

clear

public abstract void clear()

addAList

public abstract void addAList(Pair p)

toAList

public abstract Pair toAList()

keys

public abstract Pair keys()

valueEqual

public abstract 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 abstract int valueHashCode()

Description copied from class: Value

a hashCode function consistent with valueEqual

Overrides:

valueHashCode in class Value

Returns:

hash code

serialize

public abstract 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 abstract 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 abstract boolean visit(ExpressionVisitor v)

Specified by:

visit in interface ExpressionVisitee

Overrides:

visit in class Expression

display

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

Specified by:

display in class Value

Throws:

java.io.IOException
