Detailed Description

A class for storing arbitrary data in an array.

If you plan to store large hunks of data, you should consider using OFBigDataArray, which allocates the memory in pages rather than in bytes.

For security reasons, serialization and deserialization is only implemented for OFDataArrays with item size 1.
