MapConverter

Description

The MapConverter class allows you to convert arbitrary values into map objects using the following extended conversion rules:

• Objects: property names as keys, property values as values
• Arrays: element indexes as keys, elements as values

Methods

ToMap

Converts a value into a map object or returns an empty map when conversion is not possible

ToMap(value any) map[string]any

• value: any - value to convert.
• returns: map[string]any - map object or empty map when conversion is not supported.

ToMapWithDefault

Converts a value into a map object or returns a default map when conversion is not possible

ToMapWithDefault(value any, defaultValue map[string]any) map[string]any

• value: any - value to convert.
• defaultValue: map[string]any - default value.
• returns: map[string]any - map object or empty map when conversion is not supported.

ToNullableMap

Converts a value into a map object or returns nil when conversion is not possible.

ToNullableMap(value any) (map[string]any, bool)

• value: any - value to convert.
• returns: (map[string]any, bool) - map object and true or null and false when conversion is not supported.

Examples

value1, ok1 := convert.MapConverter.ToNullableMap("ABC")
value2, ok2 := convert.MapConverter.ToNullableMap(map[string]int{"key": 123})
value3, ok3 := convert.MapConverter.ToNullableMap([...]int{1, 2, 3})

fmt.Println(value1, ok1) // <nil>, false
fmt.Println(value2, ok2) // map[key:123], true
fmt.Println(value3, ok3) // map[0:1 1:2 2:3], true
