Method Details

clearData

@AnyThread
@NonNull
public GeckoResult<Void> clearData(long flags)

Clear data for all hosts.

Note: Any open session may re-accumulate previously cleared data. To ensure that no persistent data is left behind, you need to close all sessions prior to clearing data.

Parameters:

flags - Combination of StorageController.ClearFlags.

Returns:

A GeckoResult that will complete when clearing has finished.

clearDataFromHost

@AnyThread
@NonNull
public GeckoResult<Void> clearDataFromHost(@NonNull
 String host,
 long flags)

Clear data owned by the given host. Clearing data for a host will not clear data created by its third-party origins.

Note: Any open session may re-accumulate previously cleared data. To ensure that no persistent data is left behind, you need to close all sessions prior to clearing data.

Parameters:

host - The host to be used.

flags - Combination of StorageController.ClearFlags.

Returns:

A GeckoResult that will complete when clearing has finished.

clearDataFromBaseDomain

@AnyThread
@NonNull
public GeckoResult<Void> clearDataFromBaseDomain(@NonNull
 String baseDomain,
 long flags)

Clear data owned by the given base domain (eTLD+1). Clearing data for a base domain will also clear any associated third-party storage. This includes clearing for third-parties embedded by the domain and for the given domain embedded under other sites.

Note: Any open session may re-accumulate previously cleared data. To ensure that no persistent data is left behind, you need to close all sessions prior to clearing data.

Parameters:

baseDomain - The base domain to be used.

flags - Combination of StorageController.ClearFlags.

Returns:

A GeckoResult that will complete when clearing has finished.

clearDataForSessionContext

@AnyThread
public void clearDataForSessionContext(@NonNull
 String contextId)

Clear data for the given context ID. Use GeckoSessionSettings.Builder.contextId(java.lang.String).to set a context ID for a session.

Note: Any open session may re-accumulate previously cleared data. To ensure that no persistent data is left behind, you need to close all sessions for the given context prior to clearing data.

Parameters:

contextId - The context ID for the storage data to be deleted.

getAllPermissions

@AnyThread
@NonNull
public GeckoResult<List<GeckoSession.PermissionDelegate.ContentPermission>> getAllPermissions()

Get all currently stored permissions.

Returns:

A GeckoResult that will complete with a list of all currently stored GeckoSession.PermissionDelegate.ContentPermissions.

getPermissions

@AnyThread
@NonNull
public GeckoResult<List<GeckoSession.PermissionDelegate.ContentPermission>> getPermissions(@NonNull
 String uri)

Get all currently stored permissions for a given URI and default (unset) context ID.

Parameters:

uri - A String representing the URI to get permissions for.

Returns:

A GeckoResult that will complete with a list of all currently stored GeckoSession.PermissionDelegate.ContentPermissions for the URI.

getPermissions

@AnyThread
@NonNull
public GeckoResult<List<GeckoSession.PermissionDelegate.ContentPermission>> getPermissions(@NonNull
 String uri,
 @Nullable
 String contextId)

Get all currently stored permissions for a given URI and context ID.

Parameters:

uri - A String representing the URI to get permissions for.

contextId - A String specifying the context ID.

Returns:

A GeckoResult that will complete with a list of all currently stored GeckoSession.PermissionDelegate.ContentPermissions for the URI.

setPermission

@AnyThread
public void setPermission(@NonNull
 GeckoSession.PermissionDelegate.ContentPermission perm,
 int value)

Set a new value for an existing permission.

Note: in private browsing, this value will only be cleared at the end of the session to add permanent permissions in private browsing, you can use setPrivateBrowsingPermanentPermission(org.mozilla.geckoview.GeckoSession.PermissionDelegate.ContentPermission, int).

Parameters:

perm - A GeckoSession.PermissionDelegate.ContentPermission that you wish to update the value of.

value - The new value for the permission.

setPrivateBrowsingPermanentPermission

@AnyThread
public void setPrivateBrowsingPermanentPermission(@NonNull
 GeckoSession.PermissionDelegate.ContentPermission perm,
 int value)

Set a permanent value for a permission in a private browsing session.

Normally permissions in private browsing are cleared at the end of the session. This method allows you to set a permanent permission bypassing this behavior.

Note: permanent permissions in private browsing are web discoverable and might make the user more easily trackable.

Parameters:

perm - A GeckoSession.PermissionDelegate.ContentPermission that you wish to update the value of.

value - The new value for the permission.
