type ConcurrentMap struct {
	// contains filtered or unexported fields
}

ConcurrentMap is a thread safe map of type string:Anything. To avoid lock bottlenecks this map is divided to several map chunks.

func NewConcurrentMap(nChunks uint32) *ConcurrentMap

NewConcurrentMap creates a new concurrent map.

func (m *ConcurrentMap) Clear()

Clear clears the map

func (m *ConcurrentMap) Count() int

Count returns the number of elements within the map

func (m *ConcurrentMap) Get(key string) (interface{}, bool)

Get retrieves an element from map under given key.

func (m *ConcurrentMap) Has(key string) bool

Has looks up an item under specified key.

func (m *ConcurrentMap) IterCb(fn IterCb)

IterCb iterates over the map (cheapest way to read all elements in a map)

func (m *ConcurrentMap) Keys() []string

Keys returns all keys as []string

func (m *ConcurrentMap) Remove(key string) (interface{}, bool)

Remove removes an element from the map.

func (m *ConcurrentMap) Set(key string, value interface{})

Set sets the given value under the specified key.

func (m *ConcurrentMap) SetIfAbsent(key string, value interface{}) bool

SetIfAbsent sets the given value under the specified key if no value was associated with it.

type IterCb func(key string, v interface{})

IterCb is an iterator callback
