Description
Interface for Session functionality that subclasses must extend. SessionImpl objects are noncopyable.
Inheritance
Direct Base Classes: Poco::RefCountedObject
All Base Classes: Poco::RefCountedObject
Known Derived Classes: AbstractSessionImpl, PooledSessionImpl
Member Summary
Member Functions: begin, close, commit, createStatementImpl, getFeature, getProperty, isConnected, isTransaction, rollback, setFeature, setProperty
Inherited Functions: duplicate, referenceCount, release
Constructors
SessionImpl
SessionImpl();
Creates the SessionImpl.
Destructor
~SessionImpl 
virtual ~SessionImpl();
Destroys the SessionImpl.
Member Functions
begin
virtual void begin() = 0;
Starts a transaction.
close
virtual void close() = 0;
Closes the connection.
commit
virtual void commit() = 0;
Commits and ends a transaction.
createStatementImpl
virtual StatementImpl * createStatementImpl() = 0;
Creates a StatementImpl.
getFeature
virtual bool getFeature(
const std::string & name
) = 0;
Look up the state of a feature.
Features are a generic extension mechanism for session implementations. and are defined by the underlying SessionImpl instance.
Throws a NotSupportedException if the requested feature is not supported by the underlying implementation.
getProperty
virtual Poco::Any getProperty(
const std::string & name
) = 0;
Look up the value of a property.
Properties are a generic extension mechanism for session implementations. and are defined by the underlying SessionImpl instance.
Throws a NotSupportedException if the requested property is not supported by the underlying implementation.
isConnected
virtual bool isConnected() = 0;
Returns true iff session is connected, false otherwise.
isTransaction
virtual bool isTransaction() = 0;
Returns true iff a transaction is a transaction is in progress, false otherwise.
rollback
virtual void rollback() = 0;
Aborts a transaction.
setFeature
virtual void setFeature(
const std::string & name,
bool state
) = 0;
Set the state of a feature.
Features are a generic extension mechanism for session implementations. and are defined by the underlying SessionImpl instance.
Throws a NotSupportedException if the requested feature is not supported by the underlying implementation.
setProperty
virtual void setProperty(
const std::string & name,
const Poco::Any & value
) = 0;
Set the value of a property.
Properties are a generic extension mechanism for session implementations. and are defined by the underlying SessionImpl instance.
Throws a NotSupportedException if the requested property is not supported by the underlying implementation.
