public MultiList()

Method Details

getFirst

public T getFirst(int index)

Parameters:

index - index of the element to return

Returns:

the first element of the tuple at the specified position

Throws:

IndexOutOfBoundsException - if index is out of range (index invalid input: '<' 0 || index >= size())

getSecond

public U getSecond(int index)

Parameters:

index - index of the element to return

Returns:

the second element of the tuple at the specified position

Throws:

IndexOutOfBoundsException - if index is out of range (index invalid input: '<' 0 || index >= size())

getThird

public V getThird(int index)

Parameters:

index - index of the element to return

Returns:

the third element of the tuple at the specified position

Throws:

IndexOutOfBoundsException - if index is out of range (index invalid input: '<' 0 || index >= size())

add

public void add(T first,
 U second,
 V third)

Adds the tuple to the multi-list

Parameters:

first - first element of the tuple

second - second element of the tuple

third - third element of the tuple

remove

public void remove(T firstKey)

Removes the first occurrence of a tuple whose first element is equal to the specified one

Parameters:

firstKey - the first element of the tuple to remove

size

public int size()

Returns:

the number of tuples in the multi-list

filter

public MultiList<T,U,V> filter(MultiListPredicate<T,U,V> predicate)

Parameters:

predicate - a predicate that takes a tuple as input

Returns:

a multi-list containing the elements of this list that make the predicate true

forEach

public void forEach(MultiListProcedure<T,U,V> procedure)

Applies the procedure to each tuple in the multi-list

Parameters:

procedure - a procedure that takes a tuple as input
