public SynchronizedHashtable()

SynchronizedHashtable

public SynchronizedHashtable(HashtableBase delegate)

Method Detail

getDelegate

public HashtableBase getDelegate()

getEqualsProc

public Procedure getEqualsProc()

Specified by:

getEqualsProc in class HashtableBase

getHashProc

public Procedure getHashProc()

Specified by:

getHashProc in class HashtableBase

get

public Value get(Value k)

Specified by:

get in class HashtableBase

put

public Value put(Value k,
                 Value v)

Specified by:

put in class HashtableBase

remove

public Value remove(Value k)

Specified by:

remove in class HashtableBase

size

public int size()

Specified by:

size in class HashtableBase

clear

public void clear()

Specified by:

clear in class HashtableBase

addAList

public void addAList(Pair p)

Specified by:

addAList in class HashtableBase

toAList

public Pair toAList()

Specified by:

toAList in class HashtableBase

keys

public Pair keys()

Specified by:

keys in class HashtableBase

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.

Specified by:

valueEqual in class HashtableBase

Parameters:

v - the other Value

valueHashCode

public int valueHashCode()

Description copied from class: Value

a hashCode function consistent with valueEqual

Specified by:

valueHashCode in class HashtableBase

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.

Specified by:

serialize in class HashtableBase

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.

Specified by:

deserialize in class HashtableBase

Parameters:

s - the Deserializer

Throws:

java.io.IOException

visit

public boolean visit(ExpressionVisitor v)

Specified by:

visit in interface ExpressionVisitee

Specified by:

visit in class HashtableBase

display

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

Specified by:

display in class HashtableBase

Throws:

java.io.IOException
