C# 클래스 NetBase.Storage.FileTable

An on-disk table. This is loosely based on DBF of course, you can probably use it to read them. However, a lot of the fields are left empty - e.g. data types, etc. etc. These classes might make a good candidate for implementing IEnumerator

메소드 설명
AddRow ( Row r ) : void

Writes a row to disk
CalculateTotalRowSize ( ) : int
CommitToDisk ( string filename ) : void

This method is intended to be used only when creating a new table. So; e.g. not for normal writes.
Dispose ( ) : void
FileTable ( ) : System
FileTable ( string filename ) : System

Opens up a file handle on the table data and reads in the header. Note the file is held open until the FileTable is disposed.
Find ( Predicate p ) : List

Yes, I am sure there is room for optimisation here...
NextRow ( ) : Row

Retrieve the next row. Uses a seek, assuming the underlying framework will be sensible about it (we should usually already be in position)
Reset ( ) : void

Rewind the table back to the beginning
ToByteArray ( ) : byte[]

This is really only needed for sending data over the network in which case the results will (currently) always be the results of a query, and therefore always a MemoryTable
