Types

type EnumerableWithIndex

type EnumerableWithIndex[T comparable] interface {
	// Filter returns a new container containing all elements for which the given function returns a true value.
	Filter(func(index int, value T) bool) *List[T]

	containers.EnumerableWithIndex[T]
}

type Iterator

type Iterator[T comparable] struct {
	// contains filtered or unexported fields
}

Iterator holds the iterator's state

func (*Iterator[T]) Begin

func (it *Iterator[T]) Begin()

Begin resets the iterator to its initial state so that Next() will return the first element from the list.

func (*Iterator[T]) End

func (it *Iterator[T]) End()

End moves the iterator past the last element in the list

func (*Iterator[T]) First

func (it *Iterator[T]) First() bool

First moves the iterator to the first element and returns true if there was a first element in the list. If the list is empty, First() returns false. Modifies the state of the iterator.

func (*Iterator[T]) Index

func (it *Iterator[T]) Index() int

Index returns the current element's index. Does not modify the state of the iterator.

func (*Iterator[T]) Last

func (it *Iterator[T]) Last() bool

Last moves the iterator to the last element and returns true if there was a last element in the list. If the list is empty, Last() returns false. Modifies the state of the iterator.

func (*Iterator[T]) Next

func (it *Iterator[T]) Next() bool

Next returns true if there was a next element in the iteration.

func (*Iterator[T]) Prev

func (it *Iterator[T]) Prev() bool

Prev returns true if there was a previous element in the iteration.

func (*Iterator[T]) Value

func (it *Iterator[T]) Value() T

Value returns the current element's value. Does not modify the state of the iterator. in iterator we don't need to check the index, because we know that the index is valid

type List

type List[T comparable] struct {
	// contains filtered or unexported fields
}

func Map

func Map[K comparable, V comparable](l *List[K], f func(index int, value K) V) *List[V]

Map invokes the given function once for each element and returns a container containing the values returned by the given function.

func New

func New[T comparable](values ...T) *List[T]

func (*List[T]) Add

func (l *List[T]) Add(values ...T)

Add add elements to list.

func (*List[T]) All

func (l *List[T]) All(f func(index int, value T) bool) bool

All passes each element of the container to the given function and returns true if the function returns true for all elements.

func (*List[T]) Any

func (l *List[T]) Any(f func(index int, value T) bool) bool

Any passes each element of the container to the given function and returns true if the function ever returns true for any element.

func (*List[T]) Append

func (l *List[T]) Append(values ...T)

Append append the values to the end of the list.

func (*List[T]) Clear

func (l *List[T]) Clear()

Clear clean the list.

func (*List[comparable]) Contains

func (l *List[comparable]) Contains(values ...comparable) bool

Contains check whether the list contains all the values.

func (*List[T]) Each

func (l *List[T]) Each(f func(index int, value T))

Each calls the given function once for each element, passing that element's index and value.

func (*List[T]) Empty

func (l *List[T]) Empty() bool

Empty return whether the list is empty.

func (*List[T]) Filter

func (l *List[T]) Filter(f func(index int, value T) bool) *List[T]

Filter returns a new container containing all elements for which the given function returns a true value.

func (*List[T]) Find

func (l *List[T]) Find(f func(index int, value T) bool) (_ int, t T)

Find passes each element of the container to the given function and returns the first (index,value) for which the function is true or -1,nil otherwise if no element matches the criteria.

func (*List[T]) FromJSON

func (l *List[T]) FromJSON(data []byte) error

FromJSON populates list's elements from the input JSON representation.

func (*List[T]) Get

func (l *List[T]) Get(index int) (t T, ok bool)

Get get element by index.

func (*List[comparable]) IndexOf

func (l *List[comparable]) IndexOf(value comparable) int

IndexOf return the index of the first occurrence of the value. if not found return -1

func (*List[T]) Insert

func (l *List[T]) Insert(index int, values ...T)

Insert insert the values at index.

func (*List[T]) Iterator

func (l *List[T]) Iterator() Iterator[T]

Iterator returns a stateful iterator whose elements are key/value pairs.

func (*List[T]) Prepend

func (l *List[T]) Prepend(values ...T)

Prepend prepend the values to the beginning of the list.

func (*List[T]) Remove

func (l *List[T]) Remove(index int) (t T, ok bool)

Remove remove element by index. and return the removed element.

func (*List[T]) Set

func (l *List[T]) Set(index int, value T)

Set set the element at index to value.

func (*List[T]) Size

func (l *List[T]) Size() int

Size returns the number of elements within the list.

func (*List[comparable]) Sort

func (l *List[comparable]) Sort(c utils.Comparator[comparable])

Sort sort the list.

func (*List[T]) String

func (l *List[T]) String() string

String returns a string representation of container

func (*List[T]) Swap

func (l *List[T]) Swap(i, j int)

Swap swap the element at index i and j.

func (*List[T]) ToJSON

func (l *List[T]) ToJSON() ([]byte, error)

ToJSON outputs the JSON representation of list's elements.

func (*List[T]) Values

func (l *List[T]) Values() []T

Values return all the elements in the list.
