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

Static methods

toMap

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

public static Map<String, Object> toMap(Object value)

• value: Object - value to convert.
• returns: Map<String, Object> - map object or empty map when the conversion is not supported.

toMapWithDefault

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

public static Map<String, Object> toMapWithDefault(Object value, Map<String, Object> defaultValue)

• value: Object - value to convert.
• defaultValue: Map<String, Object> - default value.
• returns: Map<String, Object> - map object or empty map when the conversion is not supported.

toNullableMap

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

public static Map<String, Object> toNullableMap(Object value)

• value: Object - value to convert.
• returns: Map<String, Object> - map object or null when the conversion is not supported.

Examples

{
  Map<String, Object> value1 = MapConverted.toNullableMap("ABC"); // Result: null
  Map<String, Object> value2 = MapConverted.toNullableMap({ key: 123 }); // Result: { key: 123 }
  Map<String, Object> value3 = MapConverted.toNullableMap(new int[]{1, 2, 3}); // Result: { "0": 1, "1": 2, "2": 3 }
  }
