RecursiveMapConverter

Description

The RecursiveMapConverter class allows you to convert arbitrary values into map objects using extended conversion rules.

Important points:

• This class is similar to MapConverter. The difference is that it recursively converts all values stored in objects and arrays.

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