class aequilibrae.project.network.Link(dataset)

Bases: aequilibrae.project.network.safe_class.SafeClass

A Link object represents a single record in the links table

from aequilibrae import Project

proj = Project()
proj.open('path/to/project/folder')

all_links = proj.network.links

# Let's get a mode to work with
modes = proj.network.modes
car_mode = modes.get('c')

# We can just get one link in specific
link1 = all_links.get(4523)
link2 = all_links.get(3254)

# We can find out which fields exist for the links
which_fields_do_we_have = link1.data_fields()

# And edit each one like this
link1.lanes_ab = 3
link1.lanes_ba = 2

# we can drop a mode from the link
link1.drop_mode(car_mode)
# or link1.drop_mode('c')

# we can add a mode to the link
link2.add_mode(car_mode)
# or link2.add_mode('c')

# Or set all modes at once
link2.set_modes('cmtw')

# We can just save the link
link1.save()
link2.save()
