FilterParams class

Data transfer object used to pass filter parameters as simple key-value pairs.

See StringValueMap

Example

var filter = FilterParams.fromTuples(
    ['type', 'Type1',
    'from_create_time',  Date(2000, 0, 1),
    'to_create_time',  Date(),
    'compvared', true]
);
var paging =  PagingParams(0, 100);

myDataClient.getDataByFilter(filter, paging, (err, page) => {...});
