add_scenario

#add_scenario(name, based_on, notes) ⇒ void

EXCHANGE, UI

Adds a new scenario to the network.

network.add_scenario('MyNewScenario', nil, 'Some notes...')

Parameters

clear_selection

#clear_selection ⇒ void

EXCHANGE, UI

Clears the current selection, i.e. any WSRowObjects that are currently selected will be deselected.

control

#control ⇒ WSOpenNetwork

UI

This method can only be called from the UI on a WS Pro network object (not a control). It returns another WSOpenNetwork object which is the control. It returns nil if there is no control open in the network.

Example

net=WSApplication.current_network
control = net.control
puts control.current_scenario
net.current_scenario = '1'
control.current_scenario = '1'

control.row_objects('wn_ctl_node').each do |ro|
    puts ro.id
end

csv_export

#csv_export(filename, options) ⇒ void

EXCHANGE, UI

Exports data to CSV.

See WSBaseNetworkObject.csv_export.

csv_import

#csv_import(filename, options) ⇒ void

EXCHANGE, UI

Imports data from CSV.

See WSBaseNetworkObject.csv_import.

current_scenario

#current_scenario ⇒ String

EXCHANGE, UI

Returns the current scenario of the network. If the current scenario is the base scenario, returns the string Base (in English).

Parameters

current_scenario= (Set)

#current_scenario=(name) ⇒ void

EXCHANGE, UI

Sets the current scenario of the network. The scenario must exist.

Parameters

current_timestep

#current_timestep ⇒ Integer

EXCHANGE, UI

The WSOpenNetwork object has a current timestep corresponding to the current timestep results have when opened in the software's UI. It determines the timestep for which the 'result' method of the WSRowObject returns its value. This method returns the index of the current timestep, with the first timestep being index 0 and the final timestep begin timestep_count - 1. The value of -1, representing the 'maximum' 'timestep' is also possible. The initial value when a sim is opened in ICM Exchange will be 0 if there are time varying results, otherwise -1 for the 'maximum' 'timestep'.

puts network.current_timestep_time
=> 0

Parameters

current_timestep= (Set)

#current_timestep=(index) ⇒ void

EXCHANGE

Sets the current network timestep.

Parameters

current_timestep_time

#current_timestep_time ⇒ DateTime

EXCHANGE, UI

Returns the actual time of the current timestep.

Parameters

delete_scenario

#delete_scenario(name) ⇒ void

EXCHANGE, UI

Deletes a named scenario from the network. If the deleted scenario is the current scenario, the network will switch to the base scenario.

network.delete_scenario('ScenarioBadger')

puts network.current_scenario
=> 'Base'

Parameters

delete_selection

delete_superfluous_dummy_nodes

#delete_superfluous_dummy_nodes(tables, field) ⇒ void

EXCHANGE, UI

Deletes all objects in node tables where the named field (field parameter) is set to Y, and the object is not the upstream or downstream node in one of the tables in the array.

This method is used in conjunction with the open data import centre, where dummy nodes have been added at the ends of links (e.g. because they have been imported from a GIS where they are represented as point objects) but the links have since been deleted.

Parameters

objects_in_polygon

#objects_in_polygon(polygon, type) ⇒ Array<WSRowObject>

EXCHANGE, UI

Returns an array of the WSRowObject objects inside the polygon geometry, matching the type parameter.

When using an array of strings as the type, all values must be unique (no duplicates) and cannot contain a category and a table within the same category.

Parameters

• 'Custom Pattern' (String) : if Method is 'CUSTOM', this is the custom string format, leave unset otherwise

Parameters

row_object

#row_object(type, id) ⇒ WSRowObject?

EXCHANGE, UI

Returns a specific row object by type and ID.

node = network.row_object('wn_node', 'ST543643')
raise "Could not get node" if node.nil?

Parameters

row_object_collection

#row_object_collection(type) ⇒ WSRowObjectCollection

EXCHANGE, UI

Returns all row objects of a given type in an Array.

Parameters

row_objects_from_asset_id

#row_objects_from_asset_id(type, id) ⇒ Array<WSRowObject>

EXCHANGE, UI

Returns all row objects of a given type with this Asset ID. This method is useful when working with imported link objects, where you may not know the multi-part ID.

Asset ID's are not guaranteed to be unique, so there may be multiple results. You can use the first Array method to access the first object.

nodes = network.row_objects_from_asset_id('wn_node', 'ST543643')
puts nodes.first['asset_id']
=> 'ST543643'

You can also create your own method which enforces a single result, returning nil if no object is found or multiple objects are found:

def unique_row_object_from_asset_id(network, type, id)
  nodes = network.row_objects_from_asset_id(type, id)
  return (nodes.size != 1) ? nil : nodes.first
end

Parameters

row_objects_selection

#row_objects_selection(type) ⇒ Array<WSRowObject>

EXCHANGE, UI

Returns all selected row objects of a given type in an Array.

Parameters

run_sql

#run_sql(table, query) ⇒ void

EXCHANGE, UI

The SQL query can include multiple clauses, including saving results to a file, but cannot use any of the options that open results or prompt grids.

Parameters

save_selection

#save_selection(selection_list) ⇒ void

EXCHANGE, UI

Saves the current selection (in the current scenario) to an already existing selection list model object.

Parameters

scenarios

#scenarios { |s| ... } ⇒ String

EXCHANGE, UI

Iterates through the scenarios, yielding a String of each scenario name. The base scenario is included as the string Base in English.

  network.scenarios { |scenario| puts scenario }

  network.scenarios do |scenario|
    puts scenario
  end

Parameters

search_at_point

#search_at_point(x, y, distance, types) ⇒ Array<WSRowObject>

EXCHANGE, UI

Find all objects within a distance of a given point.

When using an array of strings as the type, all values must be unique and cannot contain a category and a table within that category. This is similar to the WSRowObject.objects_in_polygon method.

Parameters

select_in_demand_area

#select_in_demand_area(rowobject, open_control) ⇒ void

EXCHANGE, UI

Use existing WSOpenNetwork method each_selected to view selection.

Returns non zero if unable to select.

Example

#need nw and ctl
geometry_id = 7
control_id = 3

#get the relevant network and control
network = database.model_object_from_type_and_id('geometry',geometry_id)
imoc = database.model_object_from_type_and_id('control',control_id)
clds = imoc.open()
nlds = network.open()

@ro
#show the demand areas
nlds.row_objects('wn_demand_area').each do |da|
    id = da['area_id']
    if(id=="35")
        @ro = da;
    end
    puts id
end

#pass a single row object or an array
nlds.select_in_demand_area(@ro,clds);
#nlds.select_in_demand_area(nlds.row_objects('wn_demand_area'))

#show selected items
nlds.each_selected() do |itm|
    puts itm.table() + ' ' + itm.id()
end

nlds.close()
clds.close()    
database.close()    

Parameters

selection_size

#selection_size ⇒ Integer

EXCHANGE, UI

Returns the number of objects currently selected.

Parameters

set_node_namer

#set_node_namer(method, custom) ⇒ void

EXCHANGE

Sets the auto-naming convention for new nodes.

Parameters

set_projection_string

Parameters

transaction_begin

#transaction_begin ⇒ void

EXCHANGE, UI

Begins a transaction, during which you can modify network data such as adding/removing objects or changing fields. Most changes to a network must be within a transaction.

A transaction can be ended with #transaction_commit (to save the changes) or #transaction_rollback (to abandon them).

transaction_commit

#transaction_commit ⇒ void

EXCHANGE, UI

Commits any changes to the network since #transaction_begin.

transaction_rollback

#transaction_rollback ⇒ void

EXCHANGE, UI

Rolls back (ends) the transaction, which reverts any changes made since #transaction_begin.

This should be used with caution if you are storing references to WSRowObjects or associated data, as this may break references and cause an exception when you attempt to access or work with them.
