View Source RDF.BlankNode.Generator.Algorithm behaviour (RDF.ex v1.1.1)
A behaviour for implementations of blank node identifier generation algorithms.
The RDF.BlankNode.Generator
executes such an algorithm and holds its state.

Callbacks
Generates a blank node.
Generates a blank node for a given string.
Returns the initial state of the algorithm.

@callback generate(state :: map()) :: {RDF.BlankNode.t(), map()}
Generates a blank node.
An implementation should compute a blank node from the given state and return a tuple consisting of the generated blank node and the new state.
@callback generate_for(value :: any(), state :: map()) :: {RDF.BlankNode.t(), map()}
Generates a blank node for a given string.
Every call with the same string must return the same blank node.
An implementation should compute a blank node for the given string from the given state and return a tuple consisting of the generated blank node and the new state.
Returns the initial state of the algorithm.
