public class PrimIndexTable

extends Heaper

Map possibly wimpy pointers to integers. Common usage almost never does a
remove on this class, therefore we rehash in order to save time on other ops.

Constructor Detail

PrimIndexTable

public PrimIndexTable(int size,
                      boolean wimpy)

Method Detail

atIntroduce

public void atIntroduce(Heaper ptr,
                        IntegerVar index)

atStore

public void atStore(Heaper ptr,
                    IntegerVar index)

clearAll

public void clearAll()

Clear all entries from the table. I know this looks like a hack, but the
alternative is to throw away the table and build a new one: an expensive
prospect for comm.

count

public int count()

fetch

public IntegerVar fetch(Heaper ptr)

return -1 on not found.

get

public IntegerVar get(Heaper ptr)

remove

public void remove(Heaper ptr)

destruct

public void destruct()

Description copied from class: Heaper

Classes should implement this message rather than a destructor. We use this so
the destruction behavior implemented in abstract superclasses can access the
vtable of the concrete run-time type in C++. Using a message makes C++
parallel the Smalltalk semantics for delete. Destroy will actually call the destructor.

Overrides:

destruct in class Heaper

grow

public void grow()

hashFind

public int hashFind(Heaper value)

hashFindFetch

public int hashFindFetch(Heaper value)

rehash

public void rehash(PtrArray oldPtrs,
                   IntegerVarArray oldIndices,
                   int newSize)

actualHashForEqual

public int actualHashForEqual()

Overrides:

actualHashForEqual in class Heaper

stepper

public PrimIndexTableStepper stepper()

make

public static Heaper make(int size)

wimpyIndexTable

public static PrimIndexTable wimpyIndexTable(int size)
