public class ListTupleList
extends AbstractEndToEndTupleList

Implementation of TupleList that stores tuples end-to-end in a backing list.

 l1: {A,B,C},{D,E,F}
 l2: {a,b},{c,d},{e,f}

 externally looks like:
  [] <- {A,B,C,a,b}
  [] <- {A,B,C,c,d}
  [] <- {A,B,C,e,f}
  [] <- {D,E,F,a,b}
  [] <- {D,E,F,c,d}
  [] <- {D,E,F,e,d}

 but internally is:
  A,B,C,a,b,A,B,C,c,d,A,B,C,e,f,D,E,F,a,b,D,E,F,c,d,D,E,F,e,d

Constructor Detail

ListTupleList

public ListTupleList(int arity,
                     List<Member> list)

Creates a ListTupleList.

Parameters:

arity - Arity

list - Backing list

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>>

add

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

Specified by:

add in interface List<List<Member>>

Overrides:

add in class AbstractList<List<Member>>

addTuple

public void addTuple(Member... members)

clear

public void clear()

Specified by:

clear in interface Collection<List<Member>>

Specified by:

clear in interface List<List<Member>>

Overrides:

clear in class AbstractList<List<Member>>

remove

public List<Member> remove(int index)

Specified by:

remove in interface List<List<Member>>

Overrides:

remove in class AbstractList<List<Member>>

removeRange

protected void removeRange(int fromIndex,
                           int toIndex)

Overrides:

removeRange in class AbstractList<List<Member>>

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>>

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
