Parameters:

coll - the collection whose values will be placed in this list

Method Detail

iterator

public final IteratorLong iterator()

Description copied from interface: CollectionNumber

Returns an iterator over the elements of the collection.

Specified by:

iterator in interface CollectionLong

Specified by:

iterator in interface CollectionNumber

Overrides:

iterator in class ListLong

Returns:

a new iterator

size

public final int size()

Description copied from interface: CollectionNumber

Returns the number of elements in the collection.

Specified by:

size in interface CollectionNumber

Returns:

the number of elements in the collection

getLong

public long getLong(int index)

Description copied from interface: ListNumber

Returns the element at the specified position in this list casted to a long.

Specified by:

getLong in interface ListNumber

Parameters:

index - position of the element to return

Returns:

the element at the specified position in this list

setLong

public void setLong(int index,
                    long value)

Description copied from interface: ListNumber

Changes the element at the specified position, casting to the internal representation.

Specified by:

setLong in interface ListNumber

Overrides:

setLong in class ListLong

Parameters:

index - position of the element to change

value - the new value

subList

public ArrayLong subList(int fromIndex,
                         int toIndex)

Description copied from interface: ListNumber

Returns a view of the portion of this list between the specified fromIndex, inclusive, and toIndex, exclusive.

Specified by:

subList in interface ListNumber

Overrides:

subList in class ListLong

Parameters:

fromIndex - low endpoint (inclusive) of the subList

toIndex - high endpoint (exclusive) of the subList

Returns:

a view of the specified range within this list

setAll

public void setAll(int index,
                   ListNumber list)

Description copied from interface: ListNumber

Changes the elements starting at the specified position, taking them based on the internal representation.

Specified by:

setAll in interface ListNumber

Specified by:

toArray in interface CollectionNumber

Type Parameters:

T - the type of the array

Parameters:

array - the array into which the elements of this list are to be stored, if it is big enough; otherwise, a new array of the same runtime type is allocated for this purpose.

Returns:

an array containing the elements

of
