myValue

protected Heaper myValue

Constructor Detail

TableEntry

public TableEntry(Heaper value)

TableEntry

public TableEntry(TableEntry next,
                  Heaper value)

TableEntry

public TableEntry(Rcvr receiver)

Method Detail

copy

public abstract TableEntry copy()

fetchNext

public TableEntry fetchNext()

index

public IntegerValue index()

match

public abstract boolean match(Position key)

Return true if my key matches key.

matchInt

public boolean matchInt(IntegerValue index)

Return true if my key matches the position associated with index.

matchValue

public boolean matchValue(Heaper value)

Return true if my value matches value. Note that this *must* test EQ first in case the value is no longer a heaper. Otherwise we could never remove a destructed object.

position

public abstract Position position()

replaceValue

public boolean replaceValue(Heaper newValue)

Return true if my value can be replaced in place, and false if the entire entry must be replaced.

setNext

public void setNext(TableEntry next)

Change my pointer to the rest of the chain in this bucket.

value

public Heaper value()

printOn

public void printOn(java.io.PrintWriter oo)

Description copied from class: Heaper

This should rarely be overridden. In Tofu, it prints ClassName(...), where ... is either produced by printInsideOn or is ??? if printInsideOn it not overridden.

Overrides:

printOn in class Heaper

destroy

public void destroy()

temporarily don't destroy.

Overrides:

destroy in class Heaper

actualHashForEqual

public int actualHashForEqual()

Description copied from class: Heaper

Defined by subclasses to produce the value returned by hashForEqual.

Overrides:

actualHashForEqual in class Heaper

isEqual

public boolean isEqual(Heaper other)

Description copied from class: Heaper

Return true if the two objects are equal.

Specified by:

isEqual in class Heaper

sendSelfTo

public void sendSelfTo(Xmtr xmtr)

Overrides:

sendSelfTo in class Heaper

bucketStepper

public static TableStepper bucketStepper(SharedPtrArray array)

make

public static TableEntry make(IntegerValue index,
                              Heaper value)

make

public static TableEntry make(Position key,
                              Heaper value)
