either a valid value for the socket (eg: 123 for Integer socket)
or an output socket of another Node

_{Blender reference : GeometryNodeAttributeDomainSize, Node ‘Domain Size’}

from geonodes import nodes
nodes.DomainSize(geometry=self, component='CURVE', label=f"{self.node_chain_label}.spline_count")

stack(node)

Change the wrapped socket

Parameters: node (Node) – The new node owning the output socket to wrap
Returns: self

Methods are implemented in two modes:

Creation
Transformation

In creation mode, the node is considered as creating new data. The result is a new instance of DataSocket.

In transformation mode, the node is considered as transforming data which is kept in the result of the method. After the method returns, the calling DataSocket instance refers to a new Blender output socket. The stack method changes the socket the instance refers to and reinitialize properties

# 1. Creation mode
#
# to_mesh method creates a new mesh from a curve.
# The curve instance refers to the same output node socket
# We need to get the result of the method in a new variable

new_mesh = curve.to_mesh(profile_curve=circle)

# 2. Transformation mode
#
# set_shade_smooth method transforms the mesh.
# After the call, the mesh instance refers to the output socket of the
# newly created node "Set Shade Smooth". There is no need to get the result
# of the method.

mesh.set_shade_smooth()

# Note that a transformation method returns self and so, the following line
# is equivallent:

mesh = mesh.set_shade_smooth()
