None
- Returns:
The latest datetime that the node exists as an integer.
- latest_time#
Returns the latest time that the node exists.
- Returns:
The latest time that the node exists as an integer.
- layer(name)#
Return a view of Node containing the layer “name” Errors if the layer does not exist
- Returns:
The layered view
- Return type:
- layers(names)#
Return a view of Node containing all layers names Errors if any of the layers do not exist.
- Parameters:
names (list[str]) – list of layer names for the new view
- Returns:
The layered view
- Return type:
- name#
Returns the name of the node.
- Returns:
The name of the node as a string.
- neighbours#
Get the neighbours of this node.
Returns:
An iterator over the neighbours of this node.
- node_type#
Returns the type of node
- out_degree()#
Get the out-degree of this node (i.e., the number of edges that are incident to it from this node).
- Returns:
The out-degree of this node.
- out_edges#
Get the edges that point out of this node.
Returns:
An iterator over the edges that point out of this node.
- out_neighbours#
Get the neighbours of this node that point out of this node.
Returns:
An iterator over the neighbours of this node that point out of this node.
- properties#
The properties of the node
- Returns:
A list of properties.
- rolling(window, step=None)#
Creates a WindowSet with the given window size and optional step using a rolling window.
A rolling window is a window that moves forward by step size at each iteration.
- Parameters:
window (int | str) – The size of the window.
step (int | str | None) – The step size of the window. Defaults to window.
- Returns:
A WindowSet object.
- set_node_type(new_type)#
Set the type on the node. This only works if the type has not been previously set, otherwise will throw an error
- Parameters:
new_type (str) – The new type to be set
- Returns:
A result object indicating success or failure. On failure, it contains a GraphError.
- Return type:
Result
- shrink_end(end)#
Set the end of the window to the smaller of end and self.end()
- Parameters:
end (int | DateTime | str) – the new end time of the window
- Returns:
A Node object.
- shrink_start(start)#
Set the start of the window to the larger of start and self.start()
- Parameters:
start (int | DateTime | str) – the new start time of the window
- Returns:
A Node object.
- shrink_window(start, end)#
Shrink both the start and end of the window (same as calling shrink_start followed by shrink_end but more efficient)
Arguments:
- start#
Gets the start time for rolling and expanding windows for this Node
- Returns:
The earliest time that this Node is valid or None if the Node is valid for all times.
- start_date_time#
Gets the earliest datetime that this Node is valid
- Returns:
The earliest datetime that this Node is valid or None if the Node is valid for all times.
- valid_layers(names)#
Return a view of Node containing all layers names Any layers that do not exist are ignored
- Parameters:
names (list[str]) – list of layer names for the new view
- Returns:
The layered view
- Return type:
- window(start, end)#
Create a view of the Node including all events between start (inclusive) and end (exclusive)
- Parameters:
start (int | DateTime | str | None) – The start time of the window (unbounded if None).
end (int | DateTime | str | None) – The end time of the window (unbounded if None).
Returns: r A Node object.
- window_size#
Get the window size (difference between start and end) for this Node
