SchemaNode¶

RootSchemaNode

class SchemaNode¶

Represents a Node in the SchemaTree.

~SchemaNode()¶

The destructor.

Note

A SchemaNode represents a containment hierarchy. So invocation of the destructor will lead to the children of this node being destroyed.

virtual std::string path() const¶

Get the path expression representing this Node in in the NodeTree.

Returns: std::string representing the path to this Node.

virtual std::vector<SchemaNode *> find(const std::string &path) const¶

Finds descendant nodes that match the given xpath expression.

This API finds descendant nodes in the SchemaNode tree that satisfy the given path expression. See how to path.

Parameters: path – The path expression.

Returns: Vector of SchemaNode that satisfies the criterion.

Raises: YCPPPathError if the path expression in invalid, see error code for details.

Raises: YCPPInvalidArgumentError if the argument is invalid.

virtual const SchemaNode *parent() const noexcept¶

Get the Parent Node of this SchemaNode in the tree.

Returns: SchemaNode* the children of this node.

virtual std::vector<std::unique_ptr<SchemaNode>> &children() const¶

Returns the children of this SchemaNode in the NodeTree.

Returns: Child schema nodes.

virtual const SchemaNode &root() const noexcept¶

Get the root of NodeTree this node is part of

Returns: The pointer to the root.

virtual Statement statement() const¶

Returns the YANG statement associated with this SchemaNode

Returns: The pointer to the yang statement for this SchemaNode

virtual std::vector<Statement> keys() const¶

Returns vector of YANG statement corresponding the the keys.

Returns: Vector of Statement that represent keys.
