Member Function Documentation

◆ from_conf()

template<typename T>
void fable::schema::Enum< T >::from_conf ( const Conf &  )
inlineoverridevirtual

Apply the input JSON configuration.

This does not validate the input.

Implements fable::schema::Interface.

Here is the call graph for this function:

◆ json_schema()

template<typename T>
Json fable::schema::Enum< T >::json_schema ( ) const
inlineoverridevirtual

Return the JSON schema.

Example output:

{ "$schema": "http://json-schema.org/draft-07/schema#", "description": "stand-in no-operation simulator", "properties": { "vehicles": { "description": "list of vehicle names to make available", "items": { "type": "string" }, "type": "array" } }, "title": "nop", "additionalProperties": false, "type": "object" }

See the following links for the specification:

Implements fable::schema::Interface.

Here is the call graph for this function:

◆ reset_ptr()

template<typename T>
void fable::schema::Enum< T >::reset_ptr ( )
inlineoverridevirtual

Reset the internal pointer to nullptr, protecting against invalid access.

This should be used when a schema is used after the backing data has been deleted.

Implements fable::schema::Interface.

◆ to_json()

template<typename T>
void fable::schema::Enum< T >::to_json ( Json &  ) const
inlineoverridevirtual

Return the current value of the destination.

Warning: This is NOT an efficient operation, but it can be useful for cases where speed is not important.

Implements fable::schema::Interface.

◆ validate()

template<typename T>
void fable::schema::Enum< T >::validate ( const Conf &  c) const
inlineoverridevirtual

Validate the input JSON configuration.

If you don't have a Conf but would like to validate a Json type, then construct a Conf on the fly: 

s.validate(Conf{j});

This function is not provided inline to prevent incorrect use.

Implements fable::schema::Interface.

Here is the call graph for this function:
