AnyValueMap class

Cross-language implementation of dynamic object map (dictionary) what can hold values of any type. The stored values can be converted to different types using variety of accessor methods.

Example

var value1 =  AnyValueMap({ key1: 1, key2: '123.456', key3: '2018-01-01' });

value1.getAsBoolean('key1');   // Result: true
value1.getAsInteger('key2');   // Result: 123
value1.getAsFloat('key2');     // Result: 123.456
value1.getAsDateTime('key3');  // Result:  Date(2018,0,1)

Static Methods

fromMaps(List maps) AnyValueMap
Creates a new AnyValueMap by merging two or more maps. Maps defined later in the list override values from previously defined maps. [...]
fromTuples(List tuples) AnyValueMap
Creates a new AnyValueMap from a list of key-value pairs called tuples. [...]
fromTuplesArray(List tuples) AnyValueMap
Creates a new AnyValueMap from a list of key-value pairs called tuples. The method is similar to fromTuples but tuples are passed as array instead of parameters. [...]
