Constructor Detail

MultiDriverExecutableScanClass

public MultiDriverExecutableScanClass(ScanClass scDefinition,
                                      java.lang.String driverName,
                                      EntityId id)

Method Detail

getExternalInstance

public BasicScanClassInstance getExternalInstance(java.lang.String driver)

addTags

protected void addTags(java.util.Collection<ExecutableTag> tags,
                       Flags initFlags)

Description copied from class: SimpleExecutableScanClass

Adds tags to the scan class, but only initializes them if doInit is true. Not initializing would be desirable if we were transferring already initialized tags.

Overrides:

addTags in class SimpleExecutableScanClass

addHistoricalTags

public void addHistoricalTags(java.util.Collection<ExecutableTag> tags)

We can only store history for tags we drive. If someone is trying to store history for external tags, weed them out.

Specified by:

addHistoricalTags in interface ExecutableScanClass

Overrides:

addHistoricalTags in class BasicScanClassInstance

removeTags

public void removeTags(java.util.Collection<ExecutableTag> tags)

Overrides:

removeTags in class BasicScanClassInstance

runTagEvaluation

protected boolean runTagEvaluation()

Description copied from class: SimpleExecutableScanClass

Actually evaluates tags, returns whether they ran or not.

Overrides:

runTagEvaluation in class SimpleExecutableScanClass

updateInstanceInfo

public void updateInstanceInfo(ScanClassInstance instance)

Specified by:

updateInstanceInfo in interface ExecutableScanClass

Overrides:

updateInstanceInfo in class SimpleExecutableScanClass

getTags

public java.util.Collection<ExecutableTag> getTags()

Specified by:

getTags in interface ExecutableScanClass

Overrides:

getTags in class BasicScanClassInstance
