Generates plain or YANG JSON format.

Function Documentation

json_parse_buffer()

status_t json_parse_buffer	(	xmlChar *	buff,
		obj_template_t *	obj,
		dlq_hdr_t *	returnQ
	)

Parse buffer of JSON into val_value_t structs.

Defaults are not added to any objects Missing objects are not checked

A seperate parsing phase is used to fully validate the input contained in the returned val_value_t structs.

This parsing phase checks that simple types are complete and child members of complex types are valid (but maybe missing or incomplete child nodes).

Parameters

	buff	zero-terminated buffer to parse
	obj	obj_template_t for the object to parse
[out]	returnQ	address of Q to store parsed value results returnQ has 1 or more malloced val_value_t representing the parsed value(s); If top-level arry found then there may be more than 1 entry in the returnQ

Returns

return status

Here is the caller graph for this function:

json_parse_buffer_notif()

status_t json_parse_buffer_notif	(	xmlChar *	buff,
		obj_template_t *	obj,
		dlq_hdr_t *	returnQ
	)

Parse buffer of JSON into val_value_t structs.

Special version for parsing a notification message The parser will check for top-level nodes when a child node is not found.

A YANG 1.0 notification will have a notification header then a subtree for the notification event

A YANG 1.1 nested notification will have a notification header then at least one layer of data node (container or list) then a subtree for the notification event

Defaults are not added to any objects Missing objects are not checked

A seperate parsing phase is used to fully validate the input contained in the returned val_value_t structs.

This parsing phase checks that simple types are complete and child members of complex types are valid (but maybe missing or incomplete child nodes).

Parameters

	buff	zero-terminated buffer to parse
	obj	obj_template_t for the object to parse
[out]	returnQ	address of Q to store parsed value results returnQ has 1 or more malloced val_value_t representing the parsed value(s); If top-level arry found then there may be more than 1 entry in the returnQ

Returns

return status

json_parse_text()

status_t json_parse_text	(	ses_cb_t *	scb,
		xml_msg_hdr_t *	msg,
		obj_template_t *	obj,
		dlq_hdr_t *	returnQ
	)

Parse token chain representing JSON Text.

This function assumes that the msg->tkc token control block has been setup correctly in advance

     tkc = tk_new_chain();
     tk_setup_chain_json_buffs(tkc, ...);  (example!)
     tk_tokenize_input(tkc);

Makes sure that only allowed value strings or child nodes (and their values) are entered.

Defaults are not added to any objects Missing objects are not checked

A separate parsing phase is used to fully validate the input contained in the returned val_value_t structs.

This parsing phase checks that simple types are complete and child members of complex types are valid (but maybe missing or incomplete child nodes).

Parameters

	scb	session control block
[in,out]	msg	xml_msg header from the incoming RPC message msg->errQ may be appended with new errors
	obj	obj_template_t for the object to parse
[out]	returnQ	address of Q to store parsed value results returnQ has 1 or more malloced val_value_t representing the parsed value(s)

Returns

		const xmlChar **	modname,
		const xmlChar **	name,
		xmlChar **	tempbuff
	)
