Member Function Documentation

const char* Safir::Dob::PreviousEntityProxy::GetBlob

(

)

const

Get binary blob of the received entity without changeflags set.

This method will give you a pointer to the underlying representation of the object. Note that this pointer is only valid while the PreviousEntityProxy is in scope. If you want to keep the blob you must copy it using methods in Safir::Dob::Typesystem.

This method is mainly useful if all you want to do with a received object is to write it to a database or pass it over a C-interface to a library or plugin.

As an example, if you want to copy the bytes into a std::vector<char> you could do it like this "v = std::vector<char>(blob,blob+Safir::Dob::Typesystem::BlobOperations.GetSize())"

Returns

Binary blob of the received entity.

const char* Safir::Dob::PreviousEntityProxy::GetBlobWithChangeInfo

(

)

const

Get binary blob with change information.

Retrieves the entity with change flags set to indicate which members have changed since the last subscription response.
