Callbacks

generate(t)

View Source 
@callback generate(t()) :: {RDF.BlankNode.t(), t()}

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.

Link to this callback

generate_for(t, value)

View Source 
@callback generate_for(t(), value :: any()) :: {RDF.BlankNode.t(), t()}

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 value from the given state and return a tuple consisting of the generated blank node and the new state.
