public class LogicalNode extends ConstNode
Represents a boolean literal node in a formula syntax tree.

This constructor initializes a logical literal node in the expression syntax tree with the specified constant value.


 FormulaSyntaxTree syntaxTree = FormulaSyntaxTree.Parse("SUM(5,\"6\",TRUE)");
 FunctionNode functionNode = (FunctionNode) syntaxTree.getRoot();
 LogicalNode logicalNode = (LogicalNode) functionNode.getChildren().get(2);
 boolean value = logicalNode.getValue();
