Function Documentation

NT_AddSchema()

void NT_AddSchema	(	NT_Inst	inst,
		const char *	name,
		const char *	type,
		const uint8_t *	schema,
		size_t	schemaSize
	)

Registers a data schema.

Data schemas provide information for how a certain data type string can be decoded. The type string of a data schema indicates the type of the schema itself (e.g. "protobuf" for protobuf schemas, "struct" for struct schemas, etc). In NetworkTables, schemas are published just like normal topics, with the name being generated from the provided name: "/.schema/<name>". Duplicate calls to this function with the same name are silently ignored.

Parameters

inst	instance
name	Name (the string passed as the data type for topics using this schema)
type	Type of schema (e.g. "protobuf", "struct", etc)
schema	Schema data
schemaSize	Size of schema data

NT_HasSchema()

NT_Bool NT_HasSchema	(	NT_Inst	inst,
		const char *	name
	)

Returns whether there is a data schema already registered with the given name.

This does NOT perform a check as to whether the schema has already been published by another node on the network.

Parameters

inst	instance
name	Name (the string passed as the data type for topics using this schema)

Returns

True if schema already registered
