Method Detail

getTransferInfo

ITransitionManager.ITTransitionInfo getTransferInfo(org.intocps.maestro.ast.node.ATransferStm node,
                                                    org.intocps.maestro.interpreter.Context question,
                                                    String transferToName)
                                             throws org.intocps.maestro.ast.analysis.AnalysisException

Check if the manager has a new spec available that is type compatible for transfer

Parameters:

node - the transfer node used for location

question - the current context which should be used to check if available identifiers

transferToName - name of the spec to transfer to

Returns:

a transfer object or null if no transfer object is found or matches the desired name

Throws:

org.intocps.maestro.ast.analysis.AnalysisException

transfer

void transfer(Interpreter interpreter,
              ITransitionManager.ITTransitionInfo info)
       throws org.intocps.maestro.ast.analysis.AnalysisException

Perform the transfer - pausing the current interpretation flow and restarting a new interpreter reusing the context

Parameters:

interpreter - to use for the transfer

info - into to transfer to

Throws:

org.intocps.maestro.ast.analysis.AnalysisException

getSpecificationProvider

ITransitionManager.ISpecificationProvider getSpecificationProvider()
