org.dbreplicator.replication.column
Class AbstractColumnObject

java.lang.Object
  org.dbreplicator.replication.column.AbstractColumnObject

Direct Known Subclasses:

BigDecimalObject, BlobObject, BooleanObject, ByteObject, BytesObject, ClobObject, ClobStreamObject, DateObject, DoubleObject, FloatObject, IntegerObject, LongObject, SQLServerVarCharObject, StringObject, StringSQL_VariantObject, TimeObject, TimeStampObject

public abstract class AbstractColumnObject
extends java.lang.Object

This class is the abstract class which is extended by all the different type of ColumnObject classses. This is implemented so that different types of data can be written differently by different type of databases. This is most useful in case of Blob and Clob type of datatype, in which data is written in to saperate files.

Method Detail

setBlobHandlerObject

public void setBlobHandlerObject(BlobOutPutStream bo0)

setClobHandlerObject

public void setClobHandlerObject(ClobOutPutStream co0)

setColumnObject

public abstract void setColumnObject(java.sql.PreparedStatement pst,
                                     XMLElement value,
                                     int index)
                              throws java.sql.SQLException

Throws:

java.sql.SQLException

setColumnObject

public abstract void setColumnObject(java.sql.PreparedStatement pst,
                                     java.lang.String value,
                                     int index)
                              throws java.sql.SQLException

Throws:

java.sql.SQLException

write

public abstract void write(java.io.Writer bw,
                           java.sql.ResultSet rs,
                           int index,
                           java.util.ArrayList encodedCols,
                           java.lang.String col)
                    throws java.sql.SQLException,
                           java.io.IOException

This method is overridden by different ColumnObject classes. So that data can be written differently for different datatypes. It is best suitable for Blob & Clob datatypes where data is written in the saperate files.

Parameters:

bw - Writer

rs - ResultSet

index - int

encodedCols - ArrayList

col - String

Throws:

java.sql.SQLException

java.io.IOException

writeUpdate

public abstract void writeUpdate(java.io.Writer bw,

                                 int index,
                                 java.util.HashMap modifiedColumnsMap,
                                 java.lang.String columnName,
                                 java.util.ArrayList encodedCols)
