RWDBRow is an ordered collection of RWDBValue objects. RWDBRow is a relatively low level construct used by the DB Interface Module to store a row of data on its way to or from the database. It is visible to applications for two reasons:
The only semantics that RWDBRow adds to RWCollectable are:
RWDBRow is designed around the Interface/Implementation paradigm. An RWDBRow instance is an interface to a reference-counted implementation; copy constructors and assignment operators produce additional references to a shared implementation.
RWDBRow::RWDBRow | ( | ) |
The default constructor produces an empty RWDBRow.
RWDBRow::RWDBRow | ( | const RWDBRow & | rvalue | ) |
Copy constructor. The created RWDBRow shares an implementation with rvalue.
|
virtual |
The default destructor.
|
virtual |
Appends value to self.
|
virtual |
Returns the number of bytes required to store self.
Reimplemented from RWCollectable.
|
virtual |
Removes all values from the collection and deletes them.
|
virtual |
If c points to an RWDBRow, returns 0 if each RWDBValue in self compares equal to the RWDBValue in c at the same position, otherwise returns a nonzero value.
Reimplemented from RWCollectable.
|
virtual |
Returns a new, copy-constructed object of the same type as self. The caller is responsible for deleting the object.
Reimplemented from RWCollectable.
|
virtual |
Returns the total number of values in the collection.
|
virtual |
Returns a hash value for use in collection classes.
Reimplemented from RWCollectable.
|
virtual |
Redefined from class RWCollectable. Returns __RWDBROW.
Reimplemented from RWCollectable.
|
virtual |
Behaves as if compareTo(t) was invoked, returning true
if the result equals 0, false
otherwise.
Reimplemented from RWCollectable.
|
virtual |
Returns a new, default-constructed object of the same type as self. The caller is responsible for deleting the object.
Reimplemented from RWCollectable.
Assignment operator. Returns reference to self which shares an implementation with rvalue.
RWDBValue & RWDBRow::operator[] | ( | size_t | index | ) | const |
Returns a reference to the RWDBValue at position index in the collection. Throws an exception of type RWBoundsErr if index is out of range.
|
virtual |
Reads file, replacing the contents of self.
Reimplemented from RWCollectable.
|
virtual |
Reads stream, replacing the contents of self.
Reimplemented from RWCollectable.
|
virtual |
Writes the contents of self to file.
Reimplemented from RWCollectable.
|
virtual |
Writes the contents of self to stream.
Reimplemented from RWCollectable.
