org.springframework.jca.cci.object
Class MappingRecordOperation

java.lang.Object
  org.springframework.jca.cci.object.EisOperation
      org.springframework.jca.cci.object.MappingRecordOperation

All Implemented Interfaces:

InitializingBean

Direct Known Subclasses:

MappingCommAreaOperation

---

public abstract class MappingRecordOperation
extends EisOperation

EIS operation object that expects mapped input and output objects, converting to and from CCI Records.

Concrete subclasses must implement the abstract createInputRecord(RecordFactory, Object) and extractOutputData(Record) methods, to create an input Record from an object and to convert an output Record into an object, respectively.

Since:

1.2

Constructor Detail

MappingRecordOperation

public MappingRecordOperation()

Constructor that allows use as a JavaBean.

---

MappingRecordOperation

public MappingRecordOperation(ConnectionFactory connectionFactory,
                              InteractionSpec interactionSpec)

Convenient constructor with ConnectionFactory and specifications (connection and interaction).

Parameters:

connectionFactory - ConnectionFactory to use to obtain connections

Method Detail

setOutputRecordCreator

public void setOutputRecordCreator(RecordCreator creator)

Set a RecordCreator that should be used for creating default output Records.

Default is none: CCI's Interaction.execute variant that returns an output Record will be called.

Specify a RecordCreator here if you always need to call CCI's Interaction.execute variant with a passed-in output Record. This RecordCreator will then be invoked to create a default output Record instance.

See Also:

Interaction.execute(javax.resource.cci.InteractionSpec, Record), Interaction.execute(javax.resource.cci.InteractionSpec, Record, Record), CciTemplate.setOutputRecordCreator(org.springframework.jca.cci.core.RecordCreator)

---

execute

public Object execute(Object inputObject)
               throws DataAccessException

Execute the interaction encapsulated by this operation object.

Parameters:

inputObject - the input data, to be converted to a Record by the createInputRecord method

Returns:

the output data extracted with the extractOutputData method

Throws:

DataAccessException - if there is any problem

See Also:

createInputRecord(javax.resource.cci.RecordFactory, java.lang.Object), extractOutputData(javax.resource.cci.Record)

---

createInputRecord

protected abstract Record createInputRecord(RecordFactory recordFactory,
                                            Object inputObject)
                                     throws ResourceException,
                                            DataAccessException

Subclasses must implement this method to generate an input Record from an input object passed into the execute method.

Parameters:

inputObject - the passed-in input object

Returns:

the CCI input Record

Throws:

ResourceException - if thrown by a CCI method, to be auto-converted to a DataAccessException

DataAccessException

See Also:

execute(Object)

---

extractOutputData

protected abstract Object extractOutputData(Record outputRecord)
                                     throws ResourceException,
                                            SQLException,
                                            DataAccessException

Subclasses must implement this method to convert the Record returned by CCI execution into a result object for the execute method.

Parameters:

outputRecord - the Record returned by CCI execution

Returns:

the result object

Throws:

ResourceException - if thrown by a CCI method, to be auto-converted to a DataAccessException

SQLException

DataAccessException

execute(Object)
