Detailed Description

A Resolver matches type names to an actual node_type and possibly a companion options.

Typically, it would match type names directly, but other uses exist, e.g. a resolver could match IDs from a configuration file to concrete types.

It's possible to have different Resolvers by using different heuristics to implement the revolve callback.

Typedef Documentation

Resolver's structure.

const struct sol_flow_resolver* sol_flow_get_builtins_resolver ( void )

Resolver for built-in node types.

A Resolver implementation that interprets IDs as node type names and return the appropriate built-in node type.

const struct sol_flow_resolver* sol_flow_get_default_resolver ( void )

The default resolver set at compile time.

int sol_flow_resolve	(	const struct sol_flow_resolver *	resolver,
		const char *	id,
		const struct sol_flow_node_type **	type,
		struct sol_flow_node_named_options *	named_opts
	)

Function used to resolve id into a node type.

It uses resolver to translate id into a node type (returned in type) and its options if available after resolution.

When resolver is NULL, the default resolver is used.

sol_flow_node_named_options_fini() must be used to delete members in case of success.

Parameters

resolver	The resolver to be used to solve this id.
id	Id to be resolved
type	The node type for id if success, `NULL` otherwise
named_opts	Options for the resolved node type if available, `NULL` otherwise
