-base-compilationclj
(-base-compilation graph parallel?)(-base-compilation graph input-ids parallel?)Base compilation used by sequential and parallel processors. When parallel? is false, the topology is flattened to be 1-dimensional. When no inputs specified, it will create a compilation for all input nodes of the graph. Throws when any input does not exist as input of the graph.

(-topological-sort graph input-ids)Returns a parallel topological sort of the graph, as a collection of steps, where each step is a collection of node ids that can be run in parallel. Useful as a base for certain processor compilations.

compute-nodeclj
(compute-node sources handler)Returns a graph node that computes a new value from the values of its sources using handler.

contextclj
(context graph)(context graph processor)Returns a context to execute the given graph with processor.

Only CLJ: Returns a parallel processor that will execute each parallel step of the topological sort using pmap.
precompileclj
(precompile context input-labels)Creates a compilation for the given inputs-labels, and stores the result into context to
be used when processing the graph with the same input-labels in future calls to process.
Creates a compilation for the given `inputs-labels`, and stores the result into `context` to be used when processing the graph with the same `input-labels` in future calls to `process`.
processclj
(process {:keys [processor graph values] :as context} labelled-inputs)Processes the given context using labelled-inputs as {<input-node-label> <input-value>}.
If a compilation didn't exist for the current set of inputs, it will create one and store it in context.
Returns updated context.
Processes the given `context` using `labelled-inputs` as {<input-node-label> <input-value>}.
If a compilation didn't exist for the current set of inputs, it will create one and store it in `context`.

Compiles and processes a graph context for the given inputs.
-compileclj
(-compile this graph input-set)Creates a compilation to traverse the graph for the given input-set (set of input-nodes ids).
The result will be passed to -process as compilation.
Creates a compilation to traverse the `graph` for the given `input-set` (set of input-nodes ids). The result will be passed to -process as `compilation`.
