Gemstone.IO.Collections.FileBackedHashSet = function();Remarks
This constructor uses the default equality comparer for file backed lookup tables,
which is not the same as the default equality comparer for T
objects. This is because the default implementation of GetHashCode
does not provide guarantees about consistency across platforms, or even implementations
of the CLR. Instead, the default equality comparer uses a byte-for-byte comparison to
determine equality between keys and a CRC-32 for its hash code implementation. This
means the performance of the hashing function is dependent on the performance of the
serialization function.
Exceptions
| InvalidOperationException | T cannot be serialized. |
