Properties

Name	Description
Ancestors	Lazily enumerates over the ancestors of this node, i.e. the Parent, grandparent, great-grandparent and so on up to the root node.
Children	The children of this node.
Descendents	Enumerates all descendents of this node in depth first pre-order.
Errors	The Messages with Level Error associated with this node.
HasChildren	Returns `true` if this node has any Children, `false` otherwise.
HasErrors	Returns `true` if this node has any Messages with Level Error, `false` otherwise.
HasInfos	Returns `true` if this node has any Messages with Level Info, `false` otherwise.
HasMessages	Returns `true` if this node has any Messages, `false` otherwise.
HasNextSibling	Returns `true` if this node has a NextSibling, `false` otherwise.
HasParent	Returns `true` if this node has a Parent, `false` otherwise. Nodes will not have parents if they are the root node, or they have just been constructed and not yet added to a parent.
HasPreviousSibling	Returns `true` if this node has a PreviousSibling, `false` otherwise.
HasWarnings	Returns `true` if this node has any Messages with Level Warning, `false` otherwise.
IndexInParent	The index of this node in the Parent or -1 if this node has no Parent.
Infos	The Messages with Level Info associated with this node.
IsFirstChild	`true` if this node is the first child in Parent, `false` if not or if the node has no Parent.
IsLastChild	`true` if this node is the last child in Parent, `false` if not or if the node has no Parent.
Messages	The Messages associated with this node.
NextSibling	The next sibling, i.e. the child from the same Parent at the next positional index. Returns `null` if this node is the last child.
NextSiblings	Lazily enumerates over the next siblings, i.e. the children from the same Parent at subsequent positional indices in ascending index order.
Parent	The parent of this node.
PreviousSibling	The previous sibling, i.e. the child from the same Parent at the previous positional index. Returns `null` if this node is the first child.
PreviousSiblings	Lazily enumerates over the previous siblings, i.e. the children from the same Parent at precedent positional indices in descending index order.
Root	The root node, i.e. the highest parent above this node. Returns this node if it is the root, i.e. it has no parents.
SourcePosition	The position of the node in the source code.
ThisAndAncestors	Lazily enumerates over this node and its Ancestors, i.e. this node, the Parent, grandparent, great-grandparent and so on up to the root node.
ThisAndDescendents	Enumerates this node then all descendents of this node in depth first pre-order.
ThisAndDescendentsHaveErrors	Returns `true` if this node or any of its descendents have any Messages with Level Error, `false` otherwise.
ThisAndDescendentsHaveInfos	Returns `true` if this node or any of its descendents have any Messages with Level Info, `false` otherwise.
ThisAndDescendentsHaveMessages	Returns `true` if this node or any of its descendents have any Messages, `false` otherwise.
ThisAndDescendentsHaveWarnings	Returns `true` if this node or any of its descendents have any Messages with Level Warning, `false` otherwise.
ThisAndDescendentsWithErrors	Lazily enumerates over this node and its descendents returning only those that have Messages with Level Error.
ThisAndDescendentsWithInfos	Lazily enumerates over this node and its descendents returning only those that have Messages with Level Info.
ThisAndDescendentsWithMessages	Lazily enumerates over this node and its descendents returning only those that have Messages.
ThisAndDescendentsWithWarnings	Lazily enumerates over this node and its descendents returning only those that have Messages with Level Warning.
ThisAndNextSiblings	Lazily enumerates over this node then the next siblings, i.e. the children from the same Parent at subsequent positional indices in ascending index order.
ThisAndPreviousSiblings	Lazily enumerates over this node then the previous siblings, i.e. the children from the same Parent at precedent positional indices in descending index order.
Warnings	The Messages with Level Warning associated with this node.

Methods

Name	Description
AddError(String)	Adds a Message with Level Error and the specified text to this node.
AddError(String, String)	Adds a Message with Level Error and the specified text to this node.
AddInfo(String)	Adds a Message with Level Info and the specified text to this node.
AddInfo(String, String)	Adds a Message with Level Info and the specified text to this node.
AddMessage(Message)	Adds a Message to this node.
AddMessage(MessageLevel, String)	Adds a Message with the specified Level and Text to this node.
AddMessage(MessageLevel, String, String)	Adds a Message with the specified Level, Code and Text to this node.
