Method Details

configure

public void configure()
               throws ConfigurationException

Description copied from interface: IConfigurable

Configure this component.

configure() is called once at startup of the framework in the configure method of the owner of this IConfigurable. Purpose of this method is to check whether the static configuration of the object is correct. As much as possible class-instantiating should take place in the configure(), to improve performance.

In the case of a container, this will propagate the configure signal to all components that apply.

Specified by:

configure in interface IConfigurable

Overrides:

configure in class AbstractResultHandler

Throws:

ConfigurationException - in case it was not able to configure the component.

open

public void open()
          throws SenderException

Specified by:

open in interface IResultHandler

Overrides:

open in class AbstractResultHandler

Throws:

SenderException

close

public void close()
           throws SenderException

Specified by:

close in interface IResultHandler

Overrides:

close in class AbstractResultHandler

Throws:

SenderException

getLobHandle

protected abstract Object getLobHandle(IDbmsSupport dbmsSupport,
 ResultSet rs)
                                throws SenderException

Throws:

SenderException

getWriter

protected abstract Writer getWriter(IDbmsSupport dbmsSupport,
 Object lobHandle,
 ResultSet rs)
                             throws SenderException

Throws:

SenderException

updateLob

protected abstract void updateLob(IDbmsSupport dbmsSupport,
 Object lobHandle,
 ResultSet rs)
                           throws SenderException

Throws:

SenderException

createWriter

protected Writer createWriter(PipeLineSession session,
 String streamId)
                       throws Exception

Specified by:

createWriter in class ResultWriter

Throws:

Exception

finalizeResult

public String finalizeResult(PipeLineSession session,
 String streamId,
 boolean error)
                      throws Exception

Description copied from interface: IResultHandler

Called when all records in the original file are handled.

Specified by:

finalizeResult in interface IResultHandler

Overrides:

finalizeResult in class ResultWriter

Parameters:

session - current PipeLineSession

streamId - identification of the original file/stream/message containing the untransformed records

Returns:

the name or names of the output files

Throws:

Exception

setQuery

public void setQuery(String query)

The SQL query text
