Package org.pentaho.platform.api.engine

Interface ISolutionEngine

All Superinterfaces:

ILogger

public interface ISolutionEngine
extends ILogger

The Solution Engine handles loading and launching execution of solutions and action sequences. There is one solution engine per request, which can launch one or more action sequences.

                        IPentahoUrlFactory urlFactory,
                        List messages)

Executes the action sequence specified in the manner described in the parameters

Parameters:

actionPath - the path to the solution action that will lead to the requested action

processId - id for the given action sequence document

async - synchronous(false) or asynchronous(true) execution (not currently used)

instanceId - id to be handed to the runtime repository

persisted - if true, store runtime data, otherwise do not

parameterProviderMap - group of ParameterProviders, sources for inout parameters

outputHandler - handler used to query for addition parameters

listener - object notified on completion of action sequences

urlFactory - factory for building urls

messages - list into which debug, info, warning, and errors messages will be added

Returns:

IRuntimeContext the RuntimeContext associated with this action sequence execution

execute

IRuntimeContext execute(IRuntimeContext runtime,
                        String actionPath,
                        String processId,
                        boolean async,
                        boolean instanceEnds,
                        Map parameterProviderMap,
                        IOutputHandler outputHandler)

Executes the action sequence specified

Parameters:

runtime - The runtime context for the execution

actionPath - path to the action

processId - id for the given process, typically a GUID or unique id for this execution

async - true if the execution should be asynchronous.

instanceEnds - currently true indicating that the process ends with this execution

parameterProviderMap - Map of parameter providers to use for the execution

outputHandler - The output handler for dealing with user feedback

Returns:

The runtime context for the execution

Executes the in memory action sequence specified

Parameters:

actionSequenceXML - the in memory action sequence string

sequenceName - name of the action sequence

processId - id for the given process, typically a GUID or unique id for this execution

async - true if the execution should be asynchronous.

instanceEnds - currently true indicating that the process ends with this execution

setlistener

void setlistener(IActionCompleteListener listener)

Sets the action complete listener which will be called when the action is complete

Parameters:

listener - Listener to call back when execution is complete.

setlistener

void setlistener(IExecutionListener execListener)

setSession

void setSession(IPentahoSession session)

Sets the session in the solution engine

Parameters:

session - The session for this execution

getExecutionContext

IRuntimeContext getExecutionContext()

Returns:

the runtime context being used for this execution.

getStatus

int getStatus()

Returns:

Gets the current status from this execution

init

void init(IPentahoSession session)

Initialize the SolutionEngine. This method should be called immediately after object construction, and if solution engines are re-used among different IPentahoSessions to bind the solution engine to the session.

Parameters:

session - the session context for this SolutionEngine

setForcePrompt

void setForcePrompt(boolean forcePrompt)

Sets if the promp page should be forced

Parameters:

status -

setParameterXsl

void setParameterXsl(String xsl)

Sets the xsl file to be used to generate the parameter page for the current component. The parameter should be a full path from the solution root starting with a /, or it should be a path relative to the directory of the current action sequence.

Parameters:

xsl - The name of the XSL file
