Class which defines the writer for serialized data using the fast serialization optimization. A SerializationWriter instance is used to store values and objects in a byte array.

Once an instance is created, use the various methods to store the required data. ToArray() will return a byte[] containing all of the data required for deserialization. This can be stored in the SerializationInfo parameter in an ISerializable.GetObjectData() method.

As an alternative to ToArray(), if you want to apply some post-processing to the serialized bytes, such as compression, call AppendTokenTables first to ensure that the string and object token tables are appended to the stream, and then cast BaseStream to MemoryStream. You can then access the MemoryStream's internal buffer as follows:

Implementation of the ISortExpression interface. This class contains the sort clauses used in IRetrievalQuery instances.

Class which traverses a set of fields and their expressions and finds all fields which are actually mapped fields, so which have their ContainingObjectName set. These fields can then be used to be the containing field object for an expression instead of an empty expression field which doesn't have a mapping. This is necessary as llblgen pro doesn't have a 'source' definition, it determines that on the fly, which can go wrong if the projection has just expression fields and there are no relations specified.

Small struct which contains the state of a field for transaction state caching.

Constant holder for the version of this library. Because the library is signed, it has a general version, like 1.0.2003.2, but it also has an internal version, stored in this struct, which reflects the build date. Versions are always equal for the DQE's and the ORM support classes.

This class is by Ian Griffiths, see: http://www.interact-sw.co.uk/iangblog/2004/04/26/yetmoretimedlocking [FB]Comment below is by Ian as well. Class is left as-is with very minor changes in comments and code placement. Thanks to Eric Gunnerson for recommending this be a struct rather than a class - avoids a heap allocation. Thanks to Change Gillespie and Jocelyn Coulmance for pointing out the bugs that then crept in when I changed it to use struct... Thanks to John Sands for providing the necessary incentive to make me invent a way of using a struct in both release and debug builds without losing the debug leak tracking.
