Description

Interface Summary

ChangelogReaderIF	INTERNAL: A change log reader is a tuple reader that is used to read a change log relation.
DataSourceIF	INTERNAL: A data source interface.
TupleReaderIF	INTERNAL: A tuple reader is an iterator-like interface for looping through the tuples from a given relation.
ValueIF	INTERNAL: Interface for extracting values from tuples.

Class Summary

Changelog	INTERNAL: Data carrier holding the information about a change log table from the mapping file.
ChangelogReaderWrapper	INTERNAL: This tuple reader wraps an underlying tuple reader, and collapses a sequence of actions for the same key into a single final action.
Context	INTERNAL: Object used to hold contextual information while processing tuples.
CSVDataSource	INTERNAL: Data source that reads CSV files from a directory.
CSVImport	INTERNAL: Command line tool for importing comma- or semicolon separated files into a database.
DB2TM	PUBLIC: The driver class used to do conversions with DB2TM.
Entity	INTERNAL: Relation mapping concept that represents topic or association definitions.
Execute	INTERNAL: Command-line driver for DB2TM.
ExpressionVirtualColumn	INTERNAL: Represents an <expression-column> element in the mapping file.
Field	INTERNAL: Relation mapping concept that refers to a field definition belonging to an entity.
Functions	INTERNAL: A collection of DB2TM functions intended to be used in the function-column element.
FunctionVirtualColumn	INTERNAL: Virtual column that uses a function to map from old value to new value.
JDBCDataSource	INTERNAL: Data source that reads tables via JDBC.
JDBCUtils	INTERNAL: Data source that reads tables via JDBC.
MappingVirtualColumn	INTERNAL: Virtual column that used a hash table to map from old value to new value.
Prefix	INTERNAL: Represents a prefix declaration.
Processor	INTERNAL: Class that performs the actual db2tm processing.
Relation	INTERNAL: Relation mapping concept that represents a relation definition.
RelationMapping	INTERNAL: DB2TM relation mapping definition.
SynchronizationServlet	PUBLIC: Servlet that sets up and schedules DB2TM synchronization at regular intervals.
SynchronizationTask	INTERNAL: TimerTask that runs DB2TM synchronization.
Utils	INTERNAL: Helper class used by DB2TM internals.
Values	INTERNAL: Virtual column that used a hash table to map from old value to new value.

Enum Summary

ChangeType

INTERNAL: We used to have five change types (declared as static ints in ChangelogReaderIF), but reduced that to the current two.

Exception Summary

DB2TMConfigException	INTERNAL: Thrown when configuration errors are detected by DB2TM.
DB2TMException	INTERNAL: Thrown when runtime errors occur inside DB2TM.
DB2TMInputException	INTERNAL: Thrown when data input errors are detected by DB2TM.
