Class NaryEquationNode

NaryEquationNode class

This class specifies an n-ary operator equation consisting of an n-ary operator, a base (or operand), and optional upper and lower bounds.

public class NaryEquationNode : EquationNode

Properties

NameDescription
EquationType { get; }Get the equation type of the current node(Inherited from EquationNode.)
Font { get; }Returns the font of this object.(Inherited from FontSetting.)
IsHideSubscript { get; set; }Whether to display the lower bound
IsHideSuperscript { get; set; }Whether to display the upper bound
Length { get; }Gets the length of the characters.(Inherited from FontSetting.)
LimitLocation { get; set; }This attribute specifies the location of limits in n-ary operators. Limits can be either centered above and below the n-ary operator, or positioned just to the right of the operator.
NaryGrow { get; set; }This attribute specifies the growth property of n-ary operators at the document level. When off, n-ary operators such as integrals and summations do not grow to match the size of their operand height. When on, the n-ary operator grows vertically to match its operand height.
NaryOperator { get; set; }an n-ary operator.e.g “∑”. It is strongly recommended to use attribute NaryOperatorType to set n-ary operator. Use this property setting if you cannot find the character you need in a known type.
NaryOperatorType { get; set; }an n-ary operator.e.g “∑”
ParentNode { get; set; }Specifies the parent node of the current node(Inherited from EquationNode.)
StartIndex { get; }Gets the start index of the characters.(Inherited from FontSetting.)
TextOptions { get; }Returns the text options.(Inherited from FontSetting.)
override Type { get; }Represents the type of the node.(Inherited from EquationNode.)

Methods

AddChild(EquationNodeType)Insert a node of the specified type at the end of the child node list of the current node.(Inherited from EquationNode.)
override Equals(object)Determine whether the current equation node is equal to the specified node
GetChild(int)Returns the node at the specified index among the children of the current node.(Inherited from EquationNode.)
InsertAfter(EquationNodeType)Inserts the specified node after the current node.(Inherited from EquationNode.)
InsertBefore(EquationNodeType)Inserts the specified node before the current node.(Inherited from EquationNode.)
InsertChild(int, EquationNodeType)Inserts a node of the specified type at the specified index position in the current node’s child node list.(Inherited from EquationNode.)
