This class is a generic implementation of the DataFormat Interface. The Transaction Handler calls this class to handle the processing of host system requests and responses.

Constructor Summary

BasicDataFormat()

Method Summary

java.lang.Object	buildRequestTxn(DataPacket txnDataPacket, java.lang.String txnCode, java.lang.String txnType) This method converts a Data Packet request to a Host System format using a List of Transaction Fields.
boolean	moreToRequest() This method indicates there are more Packets to process from host system, the method toDataPackets() sets this flag if it determines that there is more data to be requested from the host system.
void	notifyProcessingFinished() This method is called by the Transaction Handler bean when a all processing for a transaction is complete.
void	setConnectionSpecification(java.lang.Object command, java.lang.String connectorProperties) This method sets the Connector Properties on an EAB Command Bean.
void	toDataPacketsMap(java.lang.Object txnData, java.util.Map entitiesMap, DataPacket txnDataPacket, java.lang.String txnCode, java.lang.String txnType) This method converts the Vector of Host System Txn Fields data elements into a Map of DataPackets, this method is called by the txn handler method processFindRequest( )
void	toDataPacketsVector(java.lang.Object txnData, java.util.Vector responseEntitiesVector, DataPacket txnDataPacket, java.lang.String txnCode, java.lang.String txnType) This method converts the Vector of Host System Response into a Vector of result DataPackets, this method is called by the txn handler method processRequest( )

buildRequestTxn

public java.lang.Object buildRequestTxn(DataPacket txnDataPacket,
                                        java.lang.String txnCode,
                                        java.lang.String txnType)
                                 throws ProcessingErrorException

This method converts a Data Packet request to a Host System format using a List of Transaction Fields.

Specified by:

buildRequestTxn in interface DataFormat

Parameters:

txnDataPacket - is DataPacket of transaction settings

txnCode - is the transaction code

txnType - is the transaction type

Returns:

Host System formatted Object

Throws:

ProcessingErrorException

moreToRequest

public boolean moreToRequest()

This method indicates there are more Packets to process from host system, the method toDataPackets() sets this flag if it determines that there is more data to be requested from the host system. This is required for systems that break the response into sub-parts. Transaction Handler checks this to determine if another request is to be posted to the host system..

Specified by:

moreToRequest in interface DataFormat

Returns:

boolean indicating more data to request

notifyProcessingFinished

public void notifyProcessingFinished()

This method is called by the Transaction Handler bean when a all processing for a transaction is complete. This allows the Data-Format class to clean up any temporary data and variables.

Specified by:

notifyProcessingFinished in interface DataFormat

setConnectionSpecification

public void setConnectionSpecification(java.lang.Object command,
                                       java.lang.String connectorProperties)
                                throws ProcessingErrorException

This method sets the Connector Properties on an EAB Command Bean. This method is called by the Transaction Handler Bean after it has built the request.

Parameters:

command - the Command bean to be set.

connectorProperties - is the Connector properties as determined by the Transaction Handler engine from the Destination EJB

Throws:

ProcessingErrorException

toDataPacketsMap

public void toDataPacketsMap(java.lang.Object txnData,
                             java.util.Map entitiesMap,
                             DataPacket txnDataPacket,
                             java.lang.String txnCode,
                             java.lang.String txnType)
                      throws ProcessingErrorException,
                             HostProcessingErrorException

This method converts the Vector of Host System Txn Fields data elements into a Map of DataPackets, this method is called by the txn handler method processFindRequest( )

Specified by:

toDataPacketsMap in interface DataFormat

Parameters:

txnDataPacket - DataPacket of request settings.

txnCode - is transaction code

txnType - is transaction type

txnData - data from host system.

entitiesMap - is Map of Data Packet entities created.

Throws:

ProcessingErrorException

HostProcessingErrorException

toDataPacketsVector

public void toDataPacketsVector(java.lang.Object txnData,
                                java.util.Vector responseEntitiesVector,
                                DataPacket txnDataPacket,
                                java.lang.String txnCode,
                                java.lang.String txnType)
                         throws ProcessingErrorException,
                                HostProcessingErrorException

This method converts the Vector of Host System Response into a Vector of result DataPackets, this method is called by the txn handler method processRequest( )

Specified by:
