Constructor Detail

ArrayTupleList

public ArrayTupleList(int arity)

Creates an empty ArrayTupleList with an initial capacity of 10 tuples.

Parameters:

arity - Arity

ArrayTupleList

public ArrayTupleList(int arity,
                      int initialCapacity)

Creates an empty ArrayTupleList.

Parameters:

arity - Arity

initialCapacity - Initial capacity

Method Detail

backingList

protected List<Member> backingList()

Specified by:

backingList in class AbstractEndToEndTupleList

get

public Member get(int slice,
                  int index)

Description copied from interface: TupleList

Returns a particular column of a particular row.

Note that list.get(row, column) is equivalent to list.slice(column).get(row) and list.get(row).get(column) but is more efficient for most implementations of TupleList.

Specified by:

get in interface TupleList

Overrides:

get in class AbstractTupleList

Parameters:

slice - Column ordinal

index - Row ordinal

Returns:

Member at given row and column

get

public List<Member> get(int index)

Specified by:

get in interface List<List<Member>>

Specified by:

get in class AbstractList<List<Member>>

set

public List<Member> set(int index,
                        List<Member> element)

Specified by:

set in interface List<List<Member>>

Overrides:

set in class AbstractEndToEndTupleList

addCurrent

public void addCurrent(TupleCursor tupleIter)

Specified by:

addCurrent in interface TupleList

Overrides:

addCurrent in class AbstractTupleList

size

public int size()

Specified by:

size in interface Collection<List<Member>>

Specified by:

size in interface List<List<Member>>

Specified by:

size in class AbstractCollection<List<Member>>

add

public boolean add(List<Member> members)

Specified by:

add in interface Collection<List<Member>>

Specified by:

add in interface List<List<Member>>

Overrides:

add in class AbstractList<List<Member>>

add

public void add(int index,
                List<Member> members)

Specified by:

add in interface List<List<Member>>

Overrides:

add in class AbstractList<List<Member>>

addAll

public boolean addAll(int index,
                      Collection<? extends List<Member>> c)

Specified by:

addAll in interface List<List<Member>>

Overrides:

addAll in class AbstractEndToEndTupleList

addTuple

public void addTuple(Member... members)

remove

public List<Member> remove(int index)

Specified by:

remove in interface List<List<Member>>

Overrides:

remove in class AbstractList<List<Member>>

slice

public List<Member> slice(int column)

Description copied from interface: TupleList

Returns a list of the members at a given column.

The list is modifiable if and only if this TupleList is modifiable. Adding an element to a slice will create a tuple whose members in other columns are null. Removing an element from a slicer will remove a tuple.

Parameters:

column - Ordinal of the member in each tuple to project

Returns:

List of members

cloneList

public TupleList cloneList(int capacity)

Description copied from interface: TupleList

Creates a copy of this list that has the same type and has a given capacity.

If capacity is negative, populates the list. A deep copy is made, so that it the contents of the list are not affected to changes to any backing collections.

Parameters:

capacity - Capacity

Returns:

Copy of list, empty if capacity is non-negative

tupleIteratorInternal

public TupleIterator tupleIteratorInternal()

Specified by:

tupleIteratorInternal in class AbstractTupleList
