# `RDF.BlankNode.Generator`
[🔗](https://github.com/rdf-elixir/rdf-ex/blob/v3.0.1/lib/rdf/blank_node_generator/generator.ex#L1)

A GenServer which generates `RDF.BlankNode`s using a `RDF.BlankNode.Generator.Algorithm`.

This module implements the `RDF.Resource.Generator` behaviour.
The only `RDF.Resource.Generator` configuration it requires is the process
identifier. The actual configuration of the behaviour of this generator
is done on the GenServer itself via `start_link/2` or `start/2`.

# `child_spec`

Returns a specification to start this module under a supervisor.

See `Supervisor`.

# `generate`

Generates a new blank node according to the `RDF.BlankNode.Generator.Algorithm` set up.

# `generate_for`

Generates a blank node for a given value according to the `RDF.BlankNode.Generator.Algorithm` set up.

# `start`

Starts a blank node generator process without links (outside a supervision tree).

The options are handled the same as `start_link/1`.

# `start_link`

Starts a blank node generator linked to the current process.

The `RDF.BlankNode.Generator.Algorithm` can be given either as a respective
struct or just the module, in which case a struct is created implicitly
with the default values of its fields.

# `stop`

Synchronously stops the blank node generator with the given `reason`.

It returns `:ok` if the GenServer terminates with the given reason.
If the GenServer terminates with another reason, the call will exit.

This function keeps OTP semantics regarding error reporting.
If the reason is any other than `:normal`, `:shutdown` or `{:shutdown, _}`, an
error report will be logged.
