Class Method Details

.convert_to_type(type, data) ⇒ Mixed

Convert data to the given type. This is part of the conversion from strings representing json, where the data that is passed in should already have been converted using JSON.parse. That will give us arrays and hashes, but will not set the correct data types.

Parameters:

  • type (String) —

    Type that the data should be converted to

  • data (String) —

    Data in string, array or hash of strings, or raw object format.

Returns:

  • (Mixed) —

    Data in the specified type
