    • Method Detail

      • setEnabled

        public void setEnabled​(String tableId,
                       boolean enabled)
                throws LiveViewException
        Description copied from interface: TableProviderControl
        Change the enabled state of an existing table. This is a shortcut over update when you only need to enable or disable the Table. However, it will not update anything else in the Table.
        Specified by:
        setEnabled in interface TableProviderControl
        Parameters:
        tableId - The ID of the Table to change.
        enabled - The new state to change it to.
        Throws:
        LiveViewException - if attempting to set a table that does not exist enabled. (Setting a non-existant table disabled is ignored.)

      • getTable

        public CatalogedTable getTable​(String remappedName)
        Description copied from interface: TableProviderControl
        Find the Table with this ID. If one doesn't exist, then it will return null.
        Specified by:
        getTable in interface TableProviderControl
        Parameters:
        remappedName - The ID by which the table is saved (i.e. the remapped name)
        Returns:
        null if no Table has that name.

      • getTables

        public Collection<CatalogedTable> getTables()
        Description copied from interface: TableProviderControl
        Get a collection of all the CatalogedTables that belong to your TableProvider. This list it returns is a copy of the real list, so it will not reflect any changes you might make.
        Specified by:
        getTables in interface TableProviderControl
        Returns:
        all the CatalogedTables that belong to your TableProvider

      • insert

        public void insert​(CatalogedTable catalogedTable)
        Description copied from interface: TableProviderControl
        Insert this Table. It is an error if a Table with that ID already exists.
        Specified by:
        insert in interface TableProviderControl
        Parameters:
        catalogedTable - The Table to insert. Note that the catalogedTable will be copied so further changes to it will not affect anything until you update or upsert.

        public void upsert​(CatalogedTable catalogedTable)
        Description copied from interface: TableProviderControl
        Insert or Update the Table, depending on whether or not it already exists.

        upsert in interface TableProviderControl
        Parameters:
        catalogedTable - The Table to insert. Note that the catalogedTable will be copied so further changes to it will not affect anything until you update or upsert.

      • update

        public void update​(CatalogedTable catalogedTable)
        Description copied from interface: TableProviderControl
        Update this Table. It is an error if a Table with that ID does not already exist.
        Specified by:
        update in interface TableProviderControl
        Parameters:
        catalogedTable - The Table to insert. Note that the catalogedTable will be copied so further changes to it will not affect anything until you update or upsert.

      • delete

        public void delete​(String remappedName)
        Description copied from interface: TableProviderControl

        Specified by:
        delete in interface TableProviderControl

      • shutMeDown

        public void shutMeDown()
        Description copied from interface: TableProviderControl
        Shut down the associated TableProvider. This is called by the TableProvider upon his learning that his back end is no longer available. These steps will happen on your behalf: - Your tables will all be marked as disabled (which will prevent new queries) - All your active QueryListeners will be closed. This will cause your table's removeListener method to be called. - Your shutdown method will be called - (If you haven't already done so) all your tables will be removed from the Table List (as if you had called delete on them). - If requested in the LVConf or service call, after the specified delay a new instance of your TableProvider will be started up again with the same arguments.
        Specified by:
        shutMeDown in interface TableProviderControl

      • remap

        public String remap​(String name)
        Description copied from interface: TableNameMapper
        check and remap a name. This will match the name against the selectors. Returns null if none matched, or the remapped string if one did. Note that having no mappings (either because mappings is null or empty) is legitimate, and implies a mapping of (.*) to %s (i.e. everything passes and maps to itself).
        Specified by:
        remap in interface TableNameMapper
        Parameters:
        name - the name to be remapped
        Returns:
        null for no match or the remapped name.

      • getTableFilteredAliases

        public TablePropertiesConfigurationWrapper getTableFilteredAliases​(String name)
        Description copied from interface: TableNameMapper
        This will match the name against the selector. Returns null if none matched, or TablePropertiesConfigurationWrapper instance with re-mapped string if one did. Note that having no mappings (either because mappings is null or empty) is legitimate, and implies a mapping of (.*) to %s (i.e. everything passes and maps to itself).
        Specified by:
        getTableFilteredAliases in interface TableNameMapper
        Parameters:
        name - is the name to be remapped and be wrapped in TablePropertiesConfigurationWrapper
        Returns:
        null for no match or TablePropertiesConfigurationWrapper with remapped name and a list of FilteredAlias instances for this table name

      • clearRetryCount

        public void clearRetryCount()
        Description copied from interface: TableProviderControl
        This will set the failedRetryCount to zero. The failedRetryCount is compared to the MaxRetryCount value that was set by the user in the LVConf (or the web service). This method will be called automatically if your start() method returns normally. However, if you keep the start thread and use it to poll your server (which you are welcome to do), then you should call this method yourself once you've successfully connected.
        Specified by:
        clearRetryCount in interface TableProviderControl

      • setStartThread

        public void setStartThread​(Thread thread)

      • disableAllAndRestart

        public void disableAllAndRestart()
        Description copied from interface: TableProviderControl
        When a condition arises where the table provider is unable to service any of tables, but it does not wish to have its tables removed from the system. This method will mark the providers tables as disabled and schedule a restart, if the provider has been so configured. The table provider is responsible for closing any active queries if it can no longer service them.
        Specified by:
        disableAllAndRestart in interface TableProviderControl

      • locateFile

        public File locateFile​(String filename,

                throws LiveViewException
        Description copied from interface: TableProviderControl
        This will attempt to locate a file within the project.
        Specified by:
        locateFile in interface TableProviderControl
        Parameters:
        filename - indicates a file in the LiveView project
        required - if true, this method will throw an exception if the file can't be found.
        Returns:
        reference to the actual file, or null if it could not be found (or filename was empty) and required was false.
        Throws:
        LiveViewException - thrown if the required flag was true and either filename was empty or it couldn't find the file.
