Class AbstractRowsEventDataDeserializer<T extends EventData>

java.lang.Object
  com.github.shyiko.mysql.binlog.event.deserialization.AbstractRowsEventDataDeserializer<T>

Type Parameters:

T - event data this deserializer is responsible for

All Implemented Interfaces:

EventDataDeserializer<T>

Direct Known Subclasses:

DeleteRowsEventDataDeserializer, UpdateRowsEventDataDeserializer, WriteRowsEventDataDeserializer

public abstract class AbstractRowsEventDataDeserializer<T extends EventData>
extends Object
implements EventDataDeserializer<T>

Whole class is basically a mix of open-replicator's AbstractRowEventParser and MySQLUtils. Main purpose here is to ease rows deserialization.

Current ColumnType to java type mapping is following:

 Integer: ColumnType.TINY, ColumnType.SHORT, ColumnType.LONG, ColumnType.INT24,
 ColumnType.YEAR, ColumnType.ENUM, ColumnType.SET,
 Long: ColumnType.LONGLONG,
 Float: ColumnType.FLOAT,
 Double: ColumnType.DOUBLE,
 String: ColumnType.VARCHAR, ColumnType.VAR_STRING, ColumnType.STRING,
 java.util.BitSet: ColumnType.BIT,
 java.util.Date: ColumnType.DATETIME, ColumnType.DATETIME_V2,
 java.math.BigDecimal: ColumnType.NEWDECIMAL,
 java.sql.Timestamp: ColumnType.TIMESTAMP, ColumnType.TIMESTAMP_V2,
 java.sql.Date: ColumnType.DATE,
 java.sql.Time: ColumnType.TIME, ColumnType.TIME_V2,
 byte[]: ColumnType.BLOB,
 

At the moment ColumnType.GEOMETRY is unsupported.
