Classes

class AbstractBinder

Interface for Binding data types to placeholders. 

class AbstractBinding

AbstractBinding connects a value with a placeholder via an AbstractBinder interface. 

class AbstractExtraction

AbstractExtraction is the interface class that connects output positions to concrete values retrieved via an AbstractExtractor. 

class AbstractExtractor

Interface used to extract data from a single result row. 

class AbstractPreparation

Interface for calling the appropriate AbstractPreparator method 

class AbstractPreparator

Interface used for database preparation where we first have to register all data types (and memory output locations) before extracting data, e. 

class AbstractSessionImpl

A partial implementation of SessionImpl, providing features and properties management. 

class AbstractTypeHandler

Parent class for type handlers. 

class Binding

Binding maps a value or multiple values (see Binding specializations for STL containers as well as type handlers) to database column(s). 

class BindingException

 

class Bulk

 

class BulkBinding

A BulkBinding maps a value to a column. 

class BulkExtraction

Specialization for bulk extraction of values from a query result set. 

class Column

Column class is column data container. 

class ConnectionFailedException

 

class Connector

A Connector creates SessionImpl objects. 

class CopyBinding

Binding maps a value or multiple values (see Binding specializations for STL containers as well as type handlers) to database column(s). 

class DataException

 

class Date

Date class wraps a DateTime and exposes date related interface. 

class ExecutionException

 

class ExtractException

 

class Extraction

Concrete Data Type specific extraction of values from a query result set. 

class InternalBulkExtraction

Container Data Type specialization extension for extraction of values from a query result set. 

class InternalExtraction

Vector Data Type specialization for extraction of values from a query result set. 

class LOB

Representation of a Large OBject. 

class LOBIOS

The base class for LOBInputStream and LOBOutputStream. 

class LOBInputStream

An input stream for reading from a LOB. 

class LOBOutputStream

An output stream for writing to a LOB. 

class LOBStreamBuf

This is the streambuf class used for reading from and writing to a LOB. 

class LengthExceededException

 

class Limit

Limit stores information how many rows a query should return. 

class LimitException

 

class MetaColumn

MetaColumn class contains column metadata information. 

class NoDataException

 

class NotConnectedException

 

class NotSupportedException

 

class Position

Utility class wrapping unsigned integer. 

class Preparation

Class for calling the appropriate AbstractPreparator method. 

class Range

Range stores information how many rows a query should return. 

class RecordSet

RecordSet provides access to data returned from a query. 

class Row

Row class provides a data type for RecordSet iteration purposes. 

class RowDataMissingException

 

class RowFilter

RowFilter class provides row filtering functionality. 

class RowFormatter

Row formatter is an abstract class providing definition for row formatting functionality. 

class RowIterator

RowIterator class. 

class Session

A Session holds a connection to a Database and creates Statement objects. 

class SessionFactory

A SessionFactory is a singleton class that stores Connectors and allows to create Sessions of the required type: Session ses(SessionFactory::instance(). 

class SessionImpl

Interface for Session functionality that subclasses must extend. 

class SessionPoolExhaustedException

 

class SessionPoolExistsException

 

class SessionUnavailableException

 

class SimpleRowFormatter

A simple row formatting class. 

class Statement

A Statement is used to execute SQL statements. 

class StatementCreator

A StatementCreator creates Statements. 

class StatementImpl

StatementImpl interface that subclasses must implement to define database dependent query execution. 

class Time

Time class wraps a DateTime and exposes time related interface. 

class Transaction

Transaction helps with transactions in domain logic. 

class TypeHandler

Converts Rows to a Type and the other way around. 

class UnknownDataBaseException

 

class UnknownTypeException

 

Securely control IoT edge devices from anywhere   Connect a Device
