JdbcWriter

public JdbcWriter(Connection connection,
                  String tableName)

Method Detail

getAutoCloseConnection

public boolean getAutoCloseConnection()

setAutoCloseConnection

public JdbcWriter setAutoCloseConnection(boolean closeConnection)

setJdbcType

public JdbcWriter setJdbcType(String fieldName,
                              int jdbcType)

The given Java object will be converted to the given targetSqlType before being sent to the database.

Note that this method may be used to pass database-specific abstract data types.

Parameters:

fieldName -

x - the object containing the JDBC Type parameter value

addExceptionProperties

public DataException addExceptionProperties(DataException exception)

Description copied from class: DataEndpoint

Adds this endpoint's current state to a DataException. Since this method is called whenever an exception is thrown, subclasses should override it to add their specific information.

Overrides:

addExceptionProperties in class DataWriter

write

public void write(Record record)
           throws DataException

Description copied from class: DataWriter

Writes the specified record to this DataWriter and increases the record-count by 1. Any exception raised while writing will be converted to a DataException using DataEndpoint.exception(Throwable).

Subclasses generally do not need to override this method, instead they should implement DataWriter.writeImpl(Record).

Overrides:

write in class DataWriter

Throws:

DataException

writeImpl

protected void writeImpl(Record record)
                  throws Throwable

Description copied from class: DataWriter

Overridden by subclasses to write the specified record to this DataWriter.

Specified by:

writeImpl in class DataWriter

Throws:

Throwable

open

public void open()

Description copied from class: DataEndpoint

Makes this endpoint ready for reading or writing.

Overrides:

open in class DataEndpoint

close

public void close()

Description copied from class: DataEndpoint

Indicates that this endpoint has finished reading or writing.

Overrides:

close in class DataEndpoint
