GrapeCity.Documents.Excel.Expressions.NonTerminalNode

NonTerminalNode Class

Represents a non-terminal node in a formula syntax tree.

A NonTerminalNode is a SyntaxNode that can contain one or more child nodes. It serves as the base type for composite syntax elements, such as function calls, operators, and parenthesized expressions, where the expression structure is represented by nested SyntaxNode instances.

The child collection returned by Children contains the immediate descendants of this node and is used to build and traverse the syntax tree.
