ProcessResult org.sleuthkit.autopsy.modules.embeddedfileextractor.EmbeddedFileExtractorIngestModule.process | ( | AbstractFile | file | ) |
Processes a file. Called between calls to startUp() and shutDown(). Will be called for each file in a data source.
IMPORTANT: In addition to returning ProcessResult.OK or ProcessResult.ERROR, modules should log all errors using methods provided by the org.sleuthkit.autopsy.coreutils.Logger class. Log messages should include the name and object ID of the data being processed and any other information that would be useful for debugging. If an exception has been caught by the module, the exception should be sent to the logger along with the log message so that a stack trace will appear in the application log.
file | The file to analyze. |

void org.sleuthkit.autopsy.modules.embeddedfileextractor.EmbeddedFileExtractorIngestModule.shutDown | ( | ) |
Invoked by Autopsy when an ingest job is completed (either because the data has been analyzed or because the job was cancelled), before the ingest module instance is discarded. The module should respond by doing things like releasing private resources, submitting final results, and posting a final ingest message.
IMPORTANT: If the module instances must share resources, the modules are responsible for synchronizing access to the shared resources and doing reference counting as required to release those resources correctly. Also, more than one ingest job may be in progress at any given time. This must also be taken into consideration when sharing resources between module instances. See IngestModuleReferenceCounter.

void org.sleuthkit.autopsy.modules.embeddedfileextractor.EmbeddedFileExtractorIngestModule.startUp | ( | IngestJobContext | context | ) | throws IngestModuleException |
Invoked by Autopsy to allow an ingest module instance to set up any internal data structures and acquire any private resources it will need during an ingest job. If the module depends on loading any resources, it should do so in this method so that it can throw an exception in the case of an error and alert the user. Exceptions that are thrown from startUp() are logged and stop processing of the data source.
IMPORTANT: If the module instances must share resources, the modules are responsible for synchronizing access to the shared resources and doing reference counting as required to release those resources correctly. Also, more than one ingest job may be in progress at any given time. This must also be taken into consideration when sharing resources between module instances. See IngestModuleReferenceCounter.
IMPORTANT: Start up IngestModuleException messages are displayed to the user, if a user is present. Therefore, an exception to the policy that exception messages are not localized is appropriate in this method. Also, the exception messages should be user-friendly.
context | Provides data and services specific to the ingest job and the ingest pipeline of which the module is a part. |
