Summary

The expression node factory object for creating expression node instances.

Pascal

 public property NodeFactory: TExprNodeFactory;

Description

This property is set by a compiling parser when it finds this symbol in its input stream. It is set to nil for an evaluating stream, so it is only valid to use this property in the Compile method. It is should be used to construct expression nodes with sufficient state to calculate the value of this symbol at expression evaluation time.
