Structure is not thread safe. Reference: https://en.wikipedia.org/wiki/List_%28abstract_data_type%29 enumerable.go iterator.go serialization.go Package-Level Type Names (total 2, both are exported) /* sort exporteds by: alphabet | popularity */ type Iterator (struct) Iterator holding the iterator's state Fields (total 2, neither is exported) /* 2 unexporteds ... *//* 2 unexporteds: */ index int list *List Methods (total 8, all are exported) (*T) Begin() Begin resets the iterator to its initial state (one-before-first) Call Next() to fetch the first element if any. (*T) End() End moves the iterator past the last element (one-past-the-end). Call Prev() to fetch the last element if any. (*T) First() bool First moves the iterator to the first element and returns true if there was a first element in the container. If First() returns true, then first element's index and value can be retrieved by Index() and Value(). Modifies the state of the iterator. (*T) Index() int Index returns the current element's index. Does not modify the state of the iterator. (*T) Last() bool Last moves the iterator to the last element and returns true if there was a last element in the container. If Last() returns true, then last element's index and value can be retrieved by Index() and Value(). Modifies the state of the iterator. (*T) Next() bool Next moves the iterator to the next element and returns true if there was a next element in the container. If Next() returns true, then next element's index and value can be retrieved by Index() and Value(). If Next() was called for the first time, then it will point the iterator to the first element if it exists. Modifies the state of the iterator. (*T) Prev() bool Prev moves the iterator to the previous element and returns true if there was a previous element in the container. If Prev() returns true, then previous element's index and value can be retrieved by Index() and Value(). Modifies the state of the iterator. (*T) Value() interface{} Value returns the current element's value. Does not modify the state of the iterator. Implements (at least 2, both are exported) *T : github.com/emirpasic/gods/containers.IteratorWithIndex *T : github.com/emirpasic/gods/containers.ReverseIteratorWithIndex As Outputs Of (at least one exported) func (*List).Iterator() Iterator type List (struct) List holds the elements in a slice Fields (total 2, neither is exported) /* 2 unexporteds ... *//* 2 unexporteds: */ elements []interface{} size int Methods (total 27, in which 23 are exported) (*T) Add(values ...interface{}) Add appends a value at the end of the list (*T) All(f func(index int, value interface{}) bool) bool All passes each element of the collection to the given function and returns true if the function returns true for all elements. (*T) Any(f func(index int, value interface{}) bool) bool Any passes each element of the collection to the given function and returns true if the function ever returns true for any element. (*T) Clear() Clear removes all elements from the list. (*T) Contains(values ...interface{}) bool Contains checks if elements (one or more) are present in the set. All elements have to be present in the set for the method to return true. Performance time complexity of n^2. Returns true if no arguments are passed at all, i.e. set is always super-set of empty set. (*T) Each(f func(index int, value interface{})) Each calls the given function once for each element, passing that element's index and value. (*T) Empty() bool Empty returns true if list does not contain any elements. (*T) Find(f func(index int, value interface{}) bool) (int, interface{}) 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. (*T) FromJSON(data []byte) error FromJSON populates list's elements from the input JSON representation. (*T) Get(index int) (interface{}, bool) Get returns the element at index. Second return parameter is true if index is within bounds of the array and array is not empty, otherwise false. (*T) IndexOf(value interface{}) int IndexOf returns index of provided element (*T) Insert(index int, values ...interface{}) Insert inserts values at specified index position shifting the value at that position (if any) and any subsequent elements to the right. Does not do anything if position is negative or bigger than list's size Note: position equal to list's size is valid, i.e. append. (*T) Iterator() Iterator Iterator returns a stateful iterator whose values can be fetched by an index. (*T) Map(f func(index int, value interface{}) interface{}) *List Map invokes the given function once for each element and returns a container containing the values returned by the given function. (*T) Remove(index int) Remove removes the element at the given index from the list. (*T) Select(f func(index int, value interface{}) bool) *List Select returns a new container containing all elements for which the given function returns a true value. (*T) Set(index int, value interface{}) Set the value at specified index Does not do anything if position is negative or bigger than list's size Note: position equal to list's size is valid, i.e. append. (*T) Size() int Size returns number of elements within the list. (*T) Sort(comparator utils.Comparator) Sort sorts values (in-place) using. (*T) String() string String returns a string representation of container (*T) Swap(i, j int) Swap swaps the two values at the specified positions. (*T) ToJSON() ([]byte, error) ToJSON outputs the JSON representation of list's elements. (*T) Values() []interface{} Values returns all elements in the list. /* 4 unexporteds ... *//* 4 unexporteds: */ (*T) growBy(n int) Expand the array if necessary, i.e. capacity will be reached if we add n elements (*T) resize(cap int) (*T) shrink() Shrink the array if necessary, i.e. when size is shrinkFactor percent of current capacity (*T) withinRange(index int) bool Check that the index is within bounds of the list Implements (at least 10, in which 8 are exported) *T : github.com/emirpasic/gods/lists.List *T : github.com/emirpasic/gods/containers.Container *T : github.com/emirpasic/gods/containers.EnumerableWithIndex *T : github.com/emirpasic/gods/containers.JSONDeserializer *T : github.com/emirpasic/gods/containers.JSONSerializer *T : github.com/emirpasic/gods/trees.Tree *T : expvar.Var *T : fmt.Stringer /* 2+ unexporteds ... *//* 2+ unexporteds: */ *T : context.stringer *T : runtime.stringer As Outputs Of (at least 3, all are exported) func New(values ...interface{}) *List func (*List).Map(f func(index int, value interface{}) interface{}) *List func (*List).Select(f func(index int, value interface{}) bool) *List Package-Level Functions (total 5, in which 1 are exported) func New(values ...interface{}) *List New instantiates a new list and adds the passed values, if any, to the list /* 4 unexporteds ... *//* 4 unexporteds: */ func assertEnumerableImplementation() func assertIteratorImplementation() func assertListImplementation() func assertSerializationImplementation() Package-Level Constants (total 2, neither is exported) /* 2 unexporteds ... *//* 2 unexporteds: */ const growthFactor float32 = 2 // growth by 100% const shrinkFactor float32 = 0.25 // shrink when size is 25% of capacity (0 means never shrink)
