Class SimpleDmlParser

java.lang.Object

io.debezium.connector.oracle.logminer.parser.SimpleDmlParser

All Implemented Interfaces:

DmlParser

public class SimpleDmlParser
extends Object
implements DmlParser

This class does parsing of simple DML: insert, update, delete. LogMiner supplies very simple syntax , that this parser should be sufficient to parse those. It does no support joins, merge, sub-selects and other complicated cases, which should be OK for LogMiner case
