Detailed Description

Implementing extension plugin schema parsed and compiled tree printer callback.

Typedef Documentation

typedef LY_ERR(* lyplg_ext_sprinter_ctree_clb)(struct lysc_ext_instance *ext, const struct lyspr_tree_ctx *ctx, const char **flags, const char **add_opts)

Callback to print parent node of ext or to print the contents of the extension.

Function is called in two different cases. If the printer_tree needs the tree-diagram form of a parent node, then ctx is set to NULL. In the second case, if printer_tree needs to print the contents of the extension, then ctx is set and function must prepare the nodes that should be printed using the lyplg_ext_sprinter_tree* functions.

Parameters

[in]	ext	Extension instance.
[in,out]	ctx	Context for the tree printer. Extension contents can be inserted into it by functions lyplg_ext_sprinter_ctree_add_ext_nodes(), lyplg_ext_sprinter_ctree_add_nodes() or by their ptree alternatives. It parameter is set to NULL, then flags and add_opts are used by printer_tree.
[out]	flags	Optional override tree-diagram <flags> in a parent node. If ctx is set, ignore this parameter.
[out]	add_opts	Additional tree-diagram <opts> string in a parent node which is printed before <opts>. If ctx is set, ignore this parameter.

Returns

LY_ERR value.

typedef LY_ERR(* lyplg_ext_sprinter_ctree_override_clb)(const struct lysc_node *node, const void *plugin_priv, ly_bool *skip, const char **flags, const char **add_opts)

Callback for rewriting the tree-diagram form of a specific node.

If this callback is set, then it is called for each node that belongs to the extension instance.

Parameters

[in]	node	Node whose tree-diagram form can be modified by the function.
[in,out]	plugin_priv	Private context set by plugin.
[out]	skip	Flag set to 1 removes the node from printed diagram.
[out]	flags	Override tree-diagram <flags> string in the node.
[out]	add_opts	Additional tree-diagram <opts> string in the node which is printed before <opts>.

Returns

LY_ERR value.

typedef LY_ERR(* lyplg_ext_sprinter_ptree_clb)(struct lysp_ext_instance *ext, const struct lyspr_tree_ctx *ctx, const char **flags, const char **add_opts)

Callback to print parent node of ext or to print the contents of the extension.

Function is called in two different cases. If the printer_tree needs the tree-diagram form of a parent node, then ctx is set to NULL. In the second case, if printer_tree needs to print the contents of the extension, then ctx is set and function must prepare the nodes that should be printed using the lyplg_ext_sprinter_tree* functions.

Parameters

[in]	ext	Extension instance.
[in,out]	ctx	Context for the tree printer. Extension contents can be inserted into it by functions lyplg_ext_sprinter_ctree_add_ext_nodes(), lyplg_ext_sprinter_ctree_add_nodes() or by their ptree alternatives. It parameter is set to NULL, then flags and add_opts are used by printer_tree.
[out]	flags	Optional override tree-diagram <flags> in a parent node. If ctx is set, ignore this parameter.
[out]	add_opts	Additional tree-diagram <opts> string in a parent node which is printed before <opts>. If ctx is set, ignore this parameter.

Returns

LY_ERR value.

typedef LY_ERR(* lyplg_ext_sprinter_ptree_override_clb)(const struct lysp_node *node, const void *plugin_priv, ly_bool *skip, const char **flags, const char **add_opts)

Callback for rewriting the tree-diagram form of a specific node.

If this callback is set, then it is called for each node that belongs to the extension instance.

Parameters

[in]	node	Node whose tree-diagram form can be modified by the function.
[in,out]	plugin_priv	Private context set by plugin.
[out]	skip	Flag set to 1 removes the node from printed diagram.
[out]	flags	Override tree-diagram <flags> string in the node.
[out]	add_opts	Additional tree-diagram <opts> string in the node which is printed before <opts>.

Returns

LY_ERR value.
