Description copied from class: BaseJsonReader

Writes the contents of the json node starting with the specified token into a complex vector. Token can take the following values: - START_ARRAY - the top level of json document is an array and skipping of the outer list is disabled - START_OBJECT - the top level of json document is a set of white space delimited maps or skipping of the outer list is enabled

Specified by:
