PluginConfigurationExporter

public PluginConfigurationExporter()
Method Detail

getGuiContexts

public Set<GuiContext> getGuiContexts()
Description copied from interface: InteractivePlugin
Get a set containing all items that the plugin handles. Ie. if the plugin imports reporters, return a set containing Item.REPORTER. This information is used by client applications to put the plugin in the proper place in the user interface.

Specified by:
getGuiContexts in interface InteractivePlugin
Returns:
A Set containing Item:s, or null if the plugin is not concerned about items

isInContext

public String isInContext(GuiContext context,
                          Object item)
Description copied from interface: InteractivePlugin
Check if the plugin can be used on the specified object. The item is either a BasicItem or BasicData object, or null if called from a list context. A client application should only call this method for contexts matching one of the contexts in the set returned by the InteractivePlugin.getGuiContexts() method. For GuiContext.Type.ITEM contexts an item of the correct type should be passed as a parameter.

The plug-in can response with a null value indicating success, a warning-level message or throw an exception to indicate an error-level message. Client application should normally only show error-level messages to users, unless the user has requested to see warning messages.

NOTE! Before BASE 2.4 all messages were treated as error-level messages.

Specified by:
isInContext in interface InteractivePlugin
Parameters:
context - The current context of the client application, it is one of the values found in set returned by InteractivePlugin.getGuiContexts()
item - The currently active item, it's type should match the GuiContext.getItem() type, or null if the context is a list context
Returns:
Null if the plugin can use that item, or a warning-level message explaining why the plugin can't be used

getRequestInformation

public RequestInformation getRequestInformation(GuiContext context,
                                                String command)
                                         throws BaseException
Description copied from interface: InteractivePlugin
This method will return the RequestInformation for a given command, i.e. the list of parameters and some nice help text.

Specified by:
getRequestInformation in interface InteractivePlugin
Parameters:
context - The current context of the client application, it is one of the values found in set returned by InteractivePlugin.getGuiContexts()
command - The command
Returns:
The RequestInformation for the command
Throws:
BaseException - if there is an error

configure

public void configure(GuiContext context,
                      Request request,
                      Response response)
Store configuration settings for Request.COMMAND_CONFIGURE_JOB.

Specified by:
configure in interface InteractivePlugin
Parameters:
context - The current context of the client application, it is one of the values found in set returned by InteractivePlugin.getGuiContexts()
request - Request object with the command and parameters
response - Response object in for the plugin to response through

getAbout

public About getAbout()
Returns information about this plugin

Specified by:
getAbout in interface Plugin
Returns:
An About object

supportsConfigurations

public boolean supportsConfigurations()
Always false

Specified by:
supportsConfigurations in interface Plugin
Overrides:
supportsConfigurations in class AbstractPlugin
Returns:
TRUE or FALSE

requiresConfiguration

public boolean requiresConfiguration()
Always false

Specified by:
requiresConfiguration in interface Plugin
Overrides:
requiresConfiguration in class AbstractPlugin
Returns:
TRUE or FALSE

getPermissions

public Collection<Permissions> getPermissions()
Request create and write access to File:s and Directory:s and read access to PluginConfigurations:s, PluginDefinition:s and User:s.

Specified by:
getPermissions in interface Plugin
Overrides:
getPermissions in class AbstractPlugin
Returns:
A collection of permissions or null to not use permissions

begin

protected void begin(DbControl dc)
Description copied from class: AbstractExporterPlugin
Called just before the export starts. A subclass may override this method if it needs to initialise some resources.

Overrides:
begin in class AbstractExporterPlugin
Parameters:
dc - The DbControl that is used to write to the database. A subclass may use this read from the database as well
See Also:
AbstractExporterPlugin.end(boolean)

performExport

protected void performExport(ExportOutputStream out,
                             ProgressReporter progress)
                      throws IOException
Description copied from class: AbstractExporterPlugin
Perform the export. This method replaces the ImmediateDownloadExporter.doExport(ExportOutputStream, ProgressReporter) method.

Specified by:
performExport in class AbstractExporterPlugin
Parameters:
out - Output stream to write the exported data to
progress - An optional progress reporter
Throws:
IOException

end

protected void end(boolean success)
Description copied from class: AbstractExporterPlugin
Called just after everything has been committed to the database, or immediately after an error has ocurred. A subclass should clean up any resources aquired in the AbstractExporterPlugin.begin(DbControl) method here.

Overrides:
end in class AbstractExporterPlugin
Parameters:
success - TRUE if the file was parsed successfully, FALSE otherwise
See Also:
AbstractExporterPlugin.begin(DbControl)

getSuccessMessage

protected String getSuccessMessage()
Description copied from class: AbstractExporterPlugin
Called if the export was successful to let the subclass generate a simple message that is sent back to the core and user interface. An example message might by: 178 reporters exported successfully. The default implementation always return null.

Overrides:
getSuccessMessage in class AbstractExporterPlugin

getSignalHandler

public SignalHandler getSignalHandler()
Description copied from interface: SignalTarget
Get the signal handler that is handling signals on behalf of this object. Multiple invokations of this method may receive the same or different objects. Null may be returned if, for some reason, the current object instance doesn't want to receive signals. Returning null is the same as not implementing this interface.

Specified by:
getSignalHandler in interface SignalTarget
Returns:
A SignalHandler object, or null if the current instance doesn't support signals

getConfigureJobParameters

private RequestInformation getConfigureJobParameters(Boolean requireFile)
