                                    OMAGInvalidParameterException

Set up an in memory local repository. This repository uses hashmaps to store content. It is useful for demos, testing and POCs.

Throws:

OMAGNotAuthorizedException - the supplied userId is not authorized to issue this command.

OMAGInvalidParameterException - invalid parameter.

OMAGConfigurationErrorException - unusual state in the admin server.

setGraphLocalRepository

public void setGraphLocalRepository(Map<String,Object> storageProperties)

                                    OMAGInvalidParameterException

Parameters:

storageProperties - properties used to configure the back end storage for the graph

Throws:

OMAGNotAuthorizedException - the supplied userId is not authorized to issue this command.
