Method Details

convert

DataType convert(Object value)
          throws IllegalArgumentException

Converts an arbitrary object into the correct type. Implementations should be able to handle any type passed them, often types by calling toString() on the incoming value and parsing the string. Normally, a null value will be returned as a null value, but that is up to the implementation.

Throws:

IllegalArgumentException - if the value cannot be parsed or is an invalid value.
