Constructor Detail

DelegatingTupleList

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

Creates a DelegatingTupleList.

Parameters:

arity - Arity

list - Backing list

Method Detail

tupleIteratorInternal

protected TupleIterator tupleIteratorInternal()

Specified by:

tupleIteratorInternal in class AbstractTupleList

subList

public TupleList subList(int fromIndex,
                         int toIndex)

Specified by:

subList in interface List<List<Member>>

Specified by:

subList in interface TupleList

Specified by:

subList in class AbstractTupleList

get

public List<Member> get(int index)

Specified by:

get in interface List<List<Member>>

Specified by:

get 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

set

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

Specified by:

set in interface List<List<Member>>

Overrides:

set 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)

project

public TupleList project(int[] destIndices)

withPositionCallback

public TupleList withPositionCallback(TupleList.PositionCallback positionCallback)
