Overview ¶
Package linkedhashmap is a map that preserves insertion-order.
It is backed by a hash table to store values and doubly-linked list to store ordering.
Structure is not thread safe.

Types ¶
type Iterator ¶
type Iterator struct {
// contains filtered or unexported fields
}
Iterator holding the iterator's state
func (*Iterator) Begin ¶
func (iterator *Iterator) Begin()
Begin resets the iterator to its initial state (one-before-first) Call Next() to fetch the first element if any.
func (*Iterator) End ¶
func (iterator *Iterator) End()
End moves the iterator past the last element (one-past-the-end). Call Prev() to fetch the last element if any.
func (*Iterator) First ¶
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 key and value can be retrieved by Key() and Value(). Modifies the state of the iterator
func (*Iterator) Key ¶
func (iterator *Iterator) Key() interface{}
Key returns the current element's key. Does not modify the state of the iterator.
func (*Iterator) Last ¶
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 key and value can be retrieved by Key() and Value(). Modifies the state of the iterator.
func (*Iterator) Next ¶
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 key and value can be retrieved by Key() 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.
func (*Iterator) NextTo ¶
NextTo moves the iterator to the next element from current position that satisfies the condition given by the passed function, and returns true if there was a next element in the container. If NextTo() returns true, then next element's key and value can be retrieved by Key() and Value(). Modifies the state of the iterator.
func (*Iterator) Prev ¶
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 key and value can be retrieved by Key() and Value(). Modifies the state of the iterator.
func (*Iterator) PrevTo ¶
PrevTo moves the iterator to the previous element from current position that satisfies the condition given by the passed function, and returns true if there was a next element in the container. If PrevTo() returns true, then next element's key and value can be retrieved by Key() and Value(). Modifies the state of the iterator.
type Map ¶
type Map[TKey comparable, TValue any] struct { // contains filtered or unexported fields }
Map holds the elements in a regular hash table, and uses doubly-linked list to store key ordering.
func New ¶
func New[TKey comparable, TValue any]() *Map[TKey, TValue]
New instantiates a linked-hash-map.
func (*Map[TKey, TValue]) Clear ¶
func (m *Map[TKey, TValue]) Clear()
Clear removes all elements from the map.
func (*Map[TKey, TValue]) Get ¶
Get searches the element in the map by key and returns its value or nil if key is not found in tree. Second return parameter is true if key was found, otherwise false. Key should adhere to the comparator's type assertion, otherwise method panics.
func (*Map[TKey, TValue]) GetKeys ¶ added in v0.4.0
func (m *Map[TKey, TValue]) GetKeys() []TKey
GetKeys returns all keys in-order
func (*Map[TKey, TValue]) GetValues ¶ added in v0.3.0
func (m *Map[TKey, TValue]) GetValues() []TValue
Values returns all values in-order based on the key.
func (*Map[TKey, TValue]) IsEmpty ¶ added in v0.3.0
Empty returns true if map does not contain any elements
func (*Map[TKey, TValue]) MarshalJSON ¶
MarshalJSON @implements json.Marshaler
func (*Map[TKey, TValue]) MergeWithSafe ¶ added in v0.3.0
func (*Map[TKey, TValue]) Put ¶
func (m *Map[TKey, TValue]) Put(key TKey, value TValue)
Put inserts key-value pair into the map. Key should adhere to the comparator's type assertion, otherwise method panics.
func (*Map[TKey, TValue]) Remove ¶
func (m *Map[TKey, TValue]) Remove(comparator utils.Comparator[TKey], key TKey)
Remove removes the element from the map by key. Key should adhere to the comparator's type assertion, otherwise method panics.
func (*Map[TKey, TValue]) ToString ¶ added in v0.3.0
String returns a string representation of container
func (*Map[Tkey, TValue]) UnmarshalJSON ¶
UnmarshalJSON @implements json.Unmarshaler
