Types

type AnyAnyMap 

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

func NewAnyAnyMap 

func NewAnyAnyMap(safe ...bool) *AnyAnyMap

NewAnyAnyMap creates and returns an empty hash map. The parameter <safe> is used to specify whether using map in concurrent-safety, which is false in default.

func NewAnyAnyMapFrom 

func NewAnyAnyMapFrom(data map[interface{}]interface{}, safe ...bool) *AnyAnyMap

NewAnyAnyMapFrom creates and returns a hash map from given map <data>. Note that, the param <data> map will be set as the underlying data map(no deep copy), there might be some concurrent-safe issues when changing the map outside.

func (*AnyAnyMap) Clear 

func (m *AnyAnyMap) Clear()

Clear deletes all data of the map, it will remake a new underlying data map.
