Types ¶
type Map ¶
type Map map[string]interface{}
Map represents an instance of keys mapping.
All the function returning values associated with keys will return a fallback value if the key is not present in the map or if the value can't be converted to the requested type.
func (Map) Flatten ¶
Flatten returns a "flattened" version of the map. * all nested elements are moved at the top level, with sub-level keys prefixed with the original key name using the glue string * any value whose type is different than maps or slice is returned as string representation (fmt "%v" verb) * slice elements are flattened, with their numeric index value as suffix * any pointer value is dereferenced
func (Map) GetInterface ¶
GetInterface returns the interface value associated with a key.
func (Map) GetStringSlice ¶
GetStringSlice returns the string value associated with a key.
func (*Map) Merge ¶
Merge merges the source map entries into the receiver map. If replace parameter is true, existing entries in the receiver map will be replaced with entries from the source map.
