LongKeyObjectValueTable

public LongKeyObjectValueTable(int capacity)

Method Detail

value

public VALUE value(int index)

Description copied from interface: Table

OPTIONAL operation. Returns null if unsupported.

Specified by:

value in interface Table<VALUE>

Overrides:

value in class IntArrayBasedKeyTable<VALUE>

Returns:

the value at the given index. If there's no assigned key here then null will be returned.

put

public void put(int index,
                long key,
                VALUE value)

Description copied from interface: Table

Puts (key/value) at the given index. This index must contractually be free at the point where the algorithm calls this method.

Specified by:

put in interface Table<VALUE>

Overrides:

put in class IntArrayBasedKeyTable<VALUE>

Parameters:

index - the index to put this key/value in.

key - the key to put.

value - the value to put.

putValue

public VALUE putValue(int index,
                      VALUE value)

Description copied from interface: Table

Puts, actually overwrites, the value at the given index. This index will contractually be occupied at the point where the algorithm calls this method. This new value replaces the existing value at this index.

Specified by:

putValue in interface Table<VALUE>

Overrides:

putValue in class IntArrayBasedKeyTable<VALUE>

Parameters:

index - the index to put this value in.

value - the value to put at this index.

Returns:

the existing value at this index, before this new value was put there.

move

public long move(int fromIndex,
                 int toIndex)

Description copied from interface: Table

Moves the key/value from one index to another, any hop bits stay. This is equivalent to a remove at fromIndex followed by a put at toIndex. After this method has been called there will no longer be any key/value assigned at fromIndex.

Specified by:

move in interface Table<VALUE>

Overrides:

move in class IntArrayBasedKeyTable<VALUE>

Parameters:

fromIndex - the index to move the key/value from.

toIndex - the index to move the key/value to.

Returns:

the affected key.

remove

public VALUE remove(int index)

Description copied from interface: Table

Removes the currently assigned key/value from the given index.

Specified by:

remove in interface Table<VALUE>

Overrides:

remove in class IntArrayBasedKeyTable<VALUE>

Parameters:

index - the index to remove key/value from.

Returns:

the existing value at this index.
