Interface CciOperations

All Known Implementing Classes:

CciTemplate

public interface CciOperations

Interface that specifies a basic set of CCI operations on an EIS. Implemented by CciTemplate. Not often used, but a useful option to enhance testability, as it can easily be mocked or stubbed.

Alternatively, the standard CCI infrastructure can be mocked. However, mocking this interface constitutes significantly less work.

Method Detail

execute

<T> T execute(ConnectionCallback<T> action)
       throws DataAccessException

Execute a request on an EIS with CCI, implemented as callback action working on a CCI Connection. This allows for implementing arbitrary data access operations, within Spring's managed CCI environment: that is, participating in Spring-managed transactions and converting JCA ResourceExceptions into Spring's DataAccessException hierarchy.

The callback action can return a result object, for example a domain object or a collection of domain objects.

Parameters:

action - the callback object that specifies the action

Returns:

the result object returned by the action, if any

Throws:

DataAccessException - if there is any problem

execute

<T> T execute(InteractionCallback<T> action)
       throws DataAccessException

Execute a request on an EIS with CCI, implemented as callback action working on a CCI Interaction. This allows for implementing arbitrary data access operations on a single Interaction, within Spring's managed CCI environment: that is, participating in Spring-managed transactions and converting JCA ResourceExceptions into Spring's DataAccessException hierarchy.

The callback action can return a result object, for example a domain object or a collection of domain objects.

Parameters:

action - the callback object that specifies the action

Returns:

the result object returned by the action, if any

Throws:

DataAccessException - if there is any problem

execute

Record execute(InteractionSpec spec,
               Record inputRecord)
        throws DataAccessException

Execute the specified interaction on an EIS with CCI.

Parameters:

spec - the CCI InteractionSpec instance that defines the interaction (connector-specific)

inputRecord - the input record

Returns:

the output record

Throws:

DataAccessException - if there is any problem

execute

void execute(InteractionSpec spec,
             Record inputRecord,
             Record outputRecord)
      throws DataAccessException

Execute the specified interaction on an EIS with CCI.

Parameters:

spec - the CCI InteractionSpec instance that defines the interaction (connector-specific)

inputRecord - the input record

outputRecord - the output record

Throws:

DataAccessException - if there is any problem

execute

Record execute(InteractionSpec spec,
               RecordCreator inputCreator)
        throws DataAccessException

Execute the specified interaction on an EIS with CCI.

Parameters:

spec - the CCI InteractionSpec instance that defines the interaction (connector-specific)

inputCreator - object that creates the input record to use

Returns:

the output record

Throws:

DataAccessException - if there is any problem

execute

<T> T execute(InteractionSpec spec,
              Record inputRecord,
              RecordExtractor<T> outputExtractor)
       throws DataAccessException

Execute the specified interaction on an EIS with CCI.

Parameters:

spec - the CCI InteractionSpec instance that defines the interaction (connector-specific)

inputRecord - the input record

outputExtractor - object to convert the output record to a result object

Returns:

the output data extracted with the RecordExtractor object

Throws:

DataAccessException - if there is any problem

execute

<T> T execute(InteractionSpec spec,
              RecordCreator inputCreator,
              RecordExtractor<T> outputExtractor)
       throws DataAccessException

Execute the specified interaction on an EIS with CCI.

Parameters:

spec - the CCI InteractionSpec instance that defines the interaction (connector-specific)

inputCreator - object that creates the input record to use

outputExtractor - object to convert the output record to a result object

Returns:

the output data extracted with the RecordExtractor object

Throws:

DataAccessException - if there is any problem
