Claim:
1. An apparatus for converting a value object, comprising: an object generating unit configured to read out data recorded in an input file in specific units, and to generate the value object corresponding to the specific units; an object processing unit configured to: include a byte array, the byte array storing a column value included in the specific units, include an object array, the object array storing a field value of the value object, and process one or more of provision and change of the column value; a metadata providing unit configured to provide metadata, including a size and a data type of each column included in the specific units, for the object processing unit; and a hardware processor configured to implement one or more of the object generating unit, the object processing unit, and the metadata providing unit, wherein the object processing unit comprises a decoder being set based on a format of the input file, and is further configured to: call a second method adapted to retrieve the field value of the value object corresponding to a specific column included in the specific units, and use the decoder to convert the specific column value stored in the byte array; and when the second method is called, and when the field value retrieved is a “NULL” value, the object processing unit uses the decoder to convert the specific column value, stores the converted value in the object array, and returns the converted and stored value.
