Classes in org.apache.empire.db that implement DBContextAware

Modifier and Type	Class	Description
class	DBReader	This class is used to perform database queries from a DBCommand object and access the results. In oder to perform a query call the open() function or - for single row queries - call getRecordData(); You can iterate through the rows using moveNext() or an iterator.
class	DBRecord	This class represents a record from a database table, view or query The class provides methods to create, read, update and delete records If an Idendity-column (AUTOINC) is defined, the value will be set upon creation by the dbms to the next value If a Timestamp-column is defined the value will be automatically set and concurrent changes of the record will be detected If changes to the record are made, but a rollback on the connection is performed, the changes will be reverted (Rollback-Handling) The record is Serializable either if the provided DBContext is serializable, or if the Context is provided on deserialization in a derived class.
class	DBRecordBase	This abstract class provides write access to the fields of a record The class provides methods that are useful for frontend-form development like - providing information about the allowed values for a field (field options) - providing information about whether or not a field is visible to the user - providing information about whether or not a field is required (mandantory) - providing information about whether or not a field is read-only - providing information about whether a particular field value is valid - providing information about whether a field was modified since it was read from the database - providing information about whether the record was modified Also, field value changes, can be handled using the onFieldChanged event.
class	DBRecordBean	This class represents a record from a database table, view or query Other than DBRecord it is not permanently attached to a context or rowset Thus it has a Default constructor and is essentially a dynamic bean
class	DBRecordData	This class provides access to the fields of one data-row of a table, view or query The fields can be accessed either by Column or by index There are various accessor functions for many data types.
class	DBSQLScript	DBSQLScript This class is a collection of sql command strings. The class is used for obtaining and executing DDL commands supplied by the database dbms (@see DBMSHandler.getDDLScript(DDLActionType, DBObject, DBSQLScript))
class	DBUtils	DBUtils This class provides various query functions and functions for command execution.
