Synopsis

Class ValueHolderRep is the letter class for the envelope class ValueHolder. See that class for more information.

Motivation

Copying ValueHolders should be as cheap as possible, so a counted referenced letter class is used.

Create the object for the given value.

~ValueHolderRep()

Destructor.

void link()

static void unlink (ValueHolderRep* rep)

Get the value. It throws an exception if the data type is incorrect.

void toRecord (Record&, const RecordFieldId&) const

Put the value as a field in a record.

static ValueHolderRep* fromRecord (const Record& rec, const RecordFieldId&)

Construct the object from the value in a record.

ValueHolderRep (const ValueHolderRep&)
ValueHolderRep& operator= (const ValueHolderRep&)

Forbid copy ctor and assignment.
