Detailed Description

By default, OnixS::FIX::Message and OnixS::FIX::GroupInstance classes convert all values assigned to the fields into their text presentations and store textual data. This approach optimizes message reuse when same instance of message is used to update a few fields and is sent over FIX session multiple times. Also, when message comes from the network and is deserialized from its raw (tag=value) presentation, all field values in fact represent segments of text. To have access to textual values, StringRef class was added together with new access members (FieldSet::getStringRef()). If value is accessed using FieldSet::getStringRef() member, instance of StringRef class is returned. That instance holds reference to a read-only segment of text. An important aspect is that no memory is allocated and copied while accessing field values that way.
