Adds a new vertex to the graph or updates an existing vertex

Adds a new vertex to the graph or updates an existing vertex

Reduce view and delete exploded vertices permanently

This function has the same effect as reducedView, except that the exploded vertices are deleted and no longer available for subsequent calls of multilayerView.

Convenience method for generating unique IDs based on vertex names

Use of this method is optional. A GraphBuilder is free to assign vertex IDs in different ways, provided that each vertex is assigned a unique ID of type Long.

Create a DottedGraph with a temporal epoch at time.

Create a DottedGraph with a temporal epoch at time.

Clear messages from previous operations. This function is predominantly used internally and shouldn't be called by the user unless they know what they are doing.

Create a DottedGraph with a sequence of temporal epochs with a separation of increment from the start of the timeline ending at end.

Create a DottedGraph with a sequence of temporal epochs with a separation of increment starting at start. These epochs get generated until the end of the available timeline.

Create a DottedGraph with a sequence of temporal epochs with a separation of increment starting at start. These epochs get generated until the end of the available timeline.

View the graph as a directed network (duplicated edges created by a previous call to undirectedView are removed and bi-directional edges un-merged)

Filter edges of the graph with global graph state

Filter edges of the graph

Execute algorithm step with global graph state (has access to accumulated state from previous steps and allows for accumulation of new values)

Execute algorithm step

Run a GenericallyApplicable algorithm on the graph and return results

Returns a table with a single row from the global grah state and one column per key in values

Return the graph unchanged

This is used to obtain the correct return type without performing any operations

Execute algorithm step with global graph state repeatedly for given number of iterations or until all vertices have voted to halt.

Execute algorithm step repeatedly for given number of iterations or until all vertices have voted to halt.

Switch to multilayer view and add interlayer edges.

Switch to multilayer view

After calling multilayerView, subsequent methods that manipulate vertices act on ExplodedVertices instead. If ExplodedVertex instances were already created by a previous call to multilayerView, they are preserved. Otherwise, this method creates an ExplodedVertex instance for each time point that a vertex is active.

Convenience method for converting dates into epochs to be used internally by Raphtory. This is the same function used by the add vertex and add edge functions, so can be called explicitly in a graph builder to reduce the number of conversions when performing multiple updates per tuple.

Create a DottedGraph with a sequence of temporal epochs with a separation of increment starting at start and ending at end (with a smaller step at the end if necessary).

Create a DottedGraph with a sequence of temporal epochs with a separation of increment starting at start and ending at end (with a smaller step at the end if necessary).

Reduce view and merge all exploded vertex state

Reduce view and apply the same merge strategy to convert each exploded state to vertex state

Reduce view and merge selected exploded state to vertex state

Switch computation to act on Vertex, inverse of multilayerView

This operation does nothing if the view is already reduced. Otherwise it switches back to running computations on vertices but preserves any existing ExplodedVertex instances created by previous calls to multilayerView to allow switching back-and-forth between views while preserving computational state. Computational state on ExplodedVertex instances is not accessible from the Vertex unless a merge strategy is supplied (see below).

Reverse the direction of each edge in the graph.

Note that if the graph is currently viewed as undirected, this method has no immediate effect, however, edges will be reversed on a subsequent call to directedView

Returns a table with one row per vertex and one column per key in values

If no values are provided, all of the values from the properties and the state are extracted.

Add a function to manipulate global graph state, mainly used to initialise accumulators before the next algorithm step

Creates a new TemporalGraph where the output timestamp for all queries will be in the default raphtory datetime format (yyyy-MM-dd HH:mm:ss.SSS).

Creates a new TemporalGraph where the output timestamp for all queries will be in epoch (long) format. This is the default mode when a TemporalGraph is created.

Creates a new TemporalGraph which includes all activity between startTime (inclusive) and endTime (exclusive) graph.slice(startTime, endTime) is equivalent to graph.from(startTime).until(endTime).

Creates a new TemporalGraph which includes all activity between startTime (inclusive) and endTime (exclusive) graph.slice(startTime, endTime) is equivalent to graph.from(startTime).until(endTime)
