Method Detail

getCurrentAsset

public com.flexstor.common.modules.registry.BaseInstanceI getCurrentAsset()

Returns the base instance object. It represents the node of the tree on the search retrieval frame. From the Import stand point it can represent a normal bucket or an element.

Since:

3.0

---

initialize

public boolean initialize()

Initializes the model. And checks if the installtion and configuration meets the basic requirements to do a Import. It includes : 1. There should be an import/upload subdirectory inside installation\conf. 2. It should have proper read/write/execute permissions.

Since:

3.0

---

loadUserDefaultImportSetting

public boolean loadUserDefaultImportSetting()

Loads the user's own default import setting.

---

loadSystemDefaultImportSetting

public boolean loadSystemDefaultImportSetting()

Loads the systems own default import setting in case the user does not have his\her own default import setting Or the user's own default Import setting could not be loaded.

---

reloadCurrentImportSetting

public boolean reloadCurrentImportSetting()

Reloads current import setting.

---

canPerform

public boolean canPerform()

Check if Import can be performed.

---

importFiles

public void importFiles()

Function that actually imports the assets. Note that we DO NOT allow import using the system default import setting (known by the name 'default'), therefore it first checks if the user has selected some other import setting Or created one of his\her own. Then starts the process of creation of the ActionData object. Depending whether it is called from the search retrieval frame or from the main tool bar, traversal path is created for each asset record (representing files to be imported), these asset record data objects are then added to the ActionData, and appropriate service is called. Status frame is shown to let the user know about import process step by step.

Since:

3.0

---

attachObserver

public void attachObserver(java.lang.Object object)

Attaches an observer.

Since:

3.0

---

detachObserver

public void detachObserver(java.lang.Object object)

Detaches an observer

Since:

3.0

---

notifyAllObservers

public void notifyAllObservers()

Notifies all the observers.

Overrides:

notifyAllObservers in class AbstractImportModel

Since:

3.0

---

notifyAllObservers

public void notifyAllObservers(java.lang.Object object)

Notifies all the observers with a notifying object.

Since:

3.0

---

update

public void update(java.util.Observable obs,
                   java.lang.Object obj)

Since:

3.0

---

isValidDisguise

private boolean isValidDisguise()

Checks if the disguise in the control is valid. If its from retrieval it can be a SYSTEM or STANDARD but if its from main tool bar it should be SYSTEM only. And as the same control file can be used for both, its possible that the user does not go to settings dialog to change the disguise.

Since:

3.0

---

Function, that depending on the type of the base instance, creates and returns traversalinfoitem data object.

---

doImport

private void doImport()

performInitialValidations

private void performInitialValidations()
                                throws com.flexstor.common.exceptions.ImportFailedException
