Initialize input method
This method resolves the type of the metadata if it’s a JavaBean or SDO type and
initializes the metadata interfaces appropriately.
public void
initializeInput(DataExchangeFactory dataBinding, Object metadata) throws
DESPIException
.
Purpose of the initialize input method
Implement the
initializeInput
method only if the metadata contains information
to be used to initialize the back-end connection for processing the request. For
example, if an application requires you to instantiate a corresponding component
on the back-end application to process the request.
This method should first invoke
super.initializeInput()
to initialize the cursors,
accessors and metadata.
Sample code
Here is a coding sample on how to implement the
intitializeInput
method:
public void initializeInput(DataExchangeFactory factory, Object[] metadata) throws DESPIException {
super.initializeInput(factory, metadata);
objectNaming = new ObjectNaming();
objectSerializer = new ObjectSerializer(objectNaming);
try{
objectAnnotations = super.getMetadata()
.getAnnotations(
TwineBallConstants.METADATA_NAMESPACE);
} catch(Exception e){
throw new DESPIException(e);
}
}
Initialize output method
public void initializeOutput(DataExchangeFactory dataBinding, Object
metadata) throws DESPIException
.
Purpose of the initialize output method
Implement this method if there is some initialization needed to support record
retrieval from
getNext()
.
This method should first invoke
super.initializeInput()
to initialize the cursors,
accessors and metadata.
Sample code
Here is a coding sample on how to implement the
intitializeOutput
method:
public void initializeOutput(DataExchangeFactory factory, Object[] metadata) throws DESPIException {
super.initializeOutput(factory, metadata);
objectNaming = new ObjectNaming();
objectSerializer = new ObjectSerializer(objectNaming);
try{
objectAnnotations = super.getMetadata().getAnnotations(TwineBallConstants.METADATA_NAMESPACE);
}catch(Exception e){
throw new DESPIException(e);
}
}
