ExportManager acts as a client, sending the export chart configuration to the ExportServer and delivering the exported charts through the attached listeners.

Constructor

ExportManager( [host], [port] ):
host: This is used to specify the export server host; if not specified, the default value is used.

port: This is used to specify the export server port; if not specified, the default value is used.

Methods

port( [port] )
Exporter is responsible for any individual export request made by the ExportManager. Generally, the ExportManager uses this class internally to make chart exporting request to export server.
If the port is given, then it updates the export server port with specified value. Otherwise it returns the current port.

host( [host] )
If the host is given, then it updates the export server host with specified value. Otherwise it returns the current host.

export( [export_config], [export_done_listener], [export_state_changed_listener] )
Exports charts with the specified configurations, ExportDone listener and ExportStateChanged listener, and returns an Exporter instance.

export_config: An instance of ExportConfig class containing export configurations.

export_done_listener: A callback function which is called with two arguments, result and error, when an export request is completed.

export_state_changed_listener: A callback function which is called with single argument state during chart export and emits events for every exporting steps from server. This callback can be used to track the progress on the server during chart export.

Class Exporter

Exporter is responsible for any individual export request made by the ExportManager. Generally, the ExportManager uses this class internally to make chart exporting request to export server.

Constructor

Exporter( [export_config], [export_done_listener], [export_state_changed_listener] )

export_config: An instance of ExportConfig class containing export configurations.

export_done_listener: A callback function which is called with two arguments result and error when an export request is completed.

export_state_changed_listener: A callback function which is called with single argument state during chart export and emits events for every exporting steps from server. This callback can be used to track the progress on the server during chart export.

Methods

export_config()
Returns the associated export configurations.

export_done_listener()
Returns the attached ExportDone listener.

export_state_changed_listener()
Returns the attached ExportStateChanged listener.

export_server_host()
Returns the export server host.

export_server_port()
Returns the export server port.

set_export_connection_config(host, port)
Sets export server’s IP address and port.

start()
Starts the chart exporting process according to the export configurations.

cancel()
Cancels the chart exporting request.

Class ExportConfig

  • inputSVG - Sets the path for the SVG file input.

  • templateFilePath - Sets the path of the HTML template used for dashboard export.

  • callbackFilePath - Sets the path for a Javascript file that would be injected at the bottom of the page for each export.

  • libraryDirectoryPath - Sets the root path of fusionCharts Javascript library to use the licensed version of FusionCharts.

  • asyncCapture - It shows if the export process will wait for CAPTURE_EXIT event.

  • maxWaitForCaptureExit - Sets the maximum time FusionExport would wait for the CAPTURE_EXIT event to be triggered.

  • dashboardLogo - Sets the path to the logo file.

  • dashboardHeading - Sets the title of the dashboard.

  • dashboardSubheading - Sets the sub-title of the dashboard.

  • type - Sets the format of the output file.

  • exportFile - Sets the output filename template, along with the path.

  • exportAsZip - Sets if the chart(s) will be exported as a zip file or as individual file(s).

Constructor

ExportConfig(config_dict)
Initializes the ExportConfig object with the specified configuration dictionary, if not given then an empty ExportConfig object is created.

Methods

set(config_name, config_value)
Sets a single export configuration with the specified configuration value. Also you can use [ ] operator to set the configuration like dictionary.

get(config_name)
Returns config value for the specified configuration name. Also you can use [ ] operator to access the configuration value like dictionary.

remove(config_name)
Removes the specified configuration and returns True if config_name is found, otherwise returns False. Also you can use del operator to delete a single configuration.

has(config_name)
Checks if the specified configuration is present, returning True if the config_name is found, otherwise returning False. Also you can use in operator to check a configuration is set or not.

clear()
Clears all the export configurations added earlier.

count()
Returns the number of total export configurations added. Also you can use len() function to get the total count of configurations added.

config_names()
Returns all configuration names as a list.

config_values()
Returns all configuration values as a list.

clone()
Returns a new instance of ExportConfig with same contents as the current one.

get_formatted_configs()
Returns all export configurations in JSON format.
