for (lyd_find_sibling_val(START, SCHEMA, NULL, 0, &(ELEM)); \
         (ELEM) && ((ELEM)->schema == (SCHEMA)); \
         (ELEM) = (ELEM)->next)

Macro to iterate via all schema node data instances in data siblings.

Parameters

ELEM	Iterator.

Definition at line 504 of file tree_data.h.

#define LYD_LIST_FOR_INST_SAFE	(	START,
		SCHEMA,

		ELEM
	)

Value:

for ((NEXT) = (ELEM) = NULL, lyd_find_sibling_val(START, SCHEMA, NULL, 0, &(ELEM)); \
         (ELEM) && ((ELEM)->schema == (SCHEMA)) ? ((NEXT) = (ELEM)->next, 1) : 0; \
         (ELEM) = (NEXT))

Macro to iterate via all schema node data instances in data siblings allowing to modify the list itself.

Parameters

START	Pointer to the starting sibling. Even if it is not first, all the siblings are searched.
SCHEMA	Schema node of the searched instances.
NEXT	Temporary storage to allow removing of the current iterator content.
ELEM	Iterator.

Definition at line 517 of file tree_data.h.

#define LYD_NODE_IS_ALONE ( NODE )

Value:

(((NODE)->prev == NODE) || \

(((NODE)->prev->schema != (NODE)->schema) && (!(NODE)->next || ((NODE)->schema != (NODE)->next->schema))))

Find out if the node is the only instance, i.e. it has no siblings with the same schema.

Parameters

[in] NODE Pointer to the struct lyd_node.

Returns: 1 NODE is a single instance (is alone).; 0 NODE is not alone.

    }\
    if (!(LYD_TREE_DFS_next)) { \
        /* no children */ \
        if ((ELEM) == (struct lyd_node *)(START)) { \
            /* we are done, (START) has no children */ \

Enumeration Type Documentation

enum LYD_ANYDATA_VALUETYPE

List of possible value types stored in lyd_node_any.

Enumerator
LYD_ANYDATA_DATATREE	Value is a pointer to lyd_node structure (first sibling). When provided as input parameter, the pointer is directly connected into the anydata node without duplication, caller is supposed to not manipulate with the data after a successful call (including calling lyd_free_all() on the provided data)
LYD_ANYDATA_STRING	Value is a generic string without any knowledge about its format (e.g. anyxml value in JSON encoded as string). XML sensitive characters (such as & or >) are automatically escaped when the anydata is printed in XML format.
LYD_ANYDATA_XML	Value is a string containing the serialized XML data.
LYD_ANYDATA_JSON	Value is a string containing the data modeled by YANG and encoded as I-JSON.
LYD_ANYDATA_LYB	Value is a memory chunk with the serialized data tree in LYB format.

Definition at line 554 of file tree_data.h.

enum LYD_FORMAT

Data input/output formats supported by libyang parser and printer functions.

Enumerator
LYD_UNKNOWN	unknown data format, invalid value
LYD_XML	XML instance data format
LYD_JSON	JSON instance data format
LYD_LYB	LYB instance data format

Function Documentation

LIBYANG_API_DECL LY_ERR lyd_parse_data	(	const struct ly_ctx *	ctx,
		struct lyd_node *	parent,
		struct ly_in *	in,
		LYD_FORMAT	format,
		uint32_t	parse_options,
		uint32_t	validate_options,
		struct lyd_node **	tree
	)

Parse (and validate) data from the input handler as a YANG data tree.

Parameters

[in]	ctx	Context to connect with the tree being built here.
[in]	parent	Optional parent to connect the parsed nodes to. If provided, the data are expected to describe a subtree of the YANG model instead of starting at the schema root.
[in]	in	The input handle to provide the dumped data in the specified `format` to parse (and validate).
[in]	format	Format of the input data to be parsed. Can be 0 to try to detect format from the input handler.
[in]	parse_options	Options for parser, see Data parser options.
[in]	validate_options	Options for the validation phase, see Data validation options.
[out]	tree	Full parsed data tree, note that NULL can be a valid tree. If `parent` is set, the first parsed child.

Returns: LY_SUCCESS in case of successful parsing (and validation).; LY_ERR value in case of error. Additional error information can be obtained from the context using ly_err* functions.

When parsing subtrees (i.e., when parent is non-NULL), validation is only performed on the newly parsed data. This might result in allowing invalid datastore content when the schema contains cross-branch constraints, complicated must statements, etc. When a full-datastore validation is desirable, parse all subtrees first, and then request validation of the complete datastore content.

[in]	validate_options	Options for the validation phase, see Data validation options.

		struct lyd_node **	diff
	)

Fully validate a data tree.

The data tree is modified in-place. As a result of the validation, some data might be removed from the tree. In that case, the removed items are freed, not just unlinked.

Parameters

[in,out]	tree	Data tree to recursively validate. May be changed by validation, might become NULL.
[in]	ctx	libyang context. Can be NULL if `tree` is set.
[in]	val_opts	Validation options (Data validation options).

Fully validate a data tree of a module.

The data tree is modified in-place. As a result of the validation, some data might be removed from the tree. In that case, the removed items are freed, not just unlinked.

If several modules need to be validated, the flag LYD_VALIDATE_NOT_FINAL should be used first for validation of each module and then lyd_validate_module_final() should be called also for each module. Otherwise, false-positive validation errors for foreign dependencies may occur.

Parameters

[in,out]	tree	Data tree to recursively validate. May be changed by validation, might become NULL.
[in]	module	Module whose data (and schema restrictions) to validate.
