PFSClob Class

Clob is short of Character Large Object.

A Clob can be used to store a multitude of parameters in a single PFS parameter e.g. storing vectors/matrices of coordinates. This can save space for the PFS file and improve performance of reading and handling the PFS file.

Reading data from a Clob works as iterating over a list of parameters. Calling one of the Get methods will return the "current" parameter and forward the iterator to the next parameter in the Clob.

The structure of the clob must be known beforehand, i.e. the number of Clob values and the order the different types of values in must match the order of methods called for retrieving the values. If that is not the case, an exception is thrown, i.e. if the next value in the Clob is a double, and the GetString method is called, an exception is thrown.
