CppExpressionGenerator Class Reference
[Generating C++ code]

#include <cppexprgenerator.h>

List of all members.

Detailed Description

Helper class for NEDCppGenerator.

Should be used in the following manner:

1. before entering a module declaration, collectExpressions() and generateExpressionClasses() should be called

2. inside the module, where expressions are actually used, generateExpressionUsage() should be called after outputting text like "value="

The internal needsExpressionClass() method decides which expressions are compiled inline and which with expression classes.

void CppExpressionGenerator::collectExpressionInfo (  ExpressionNode *  expr,

void CppExpressionGenerator::collectExpressions (  NEDElement *  node  ) 
 

Recursively finds all <expression> tags within the passed node, and stores references to them.

void CppExpressionGenerator::generateExpressionClass (  ExpressionInfo &  info  )  [protected]
 

void CppExpressionGenerator::generateExpressionClasses (   ) 
 

Generate compiled expression classes (those derived from cExpression) from all stored expressions.

The evaluate() methods of the generated classes will hold the expressions.

void CppExpressionGenerator::generateExpressionUsage (  ExpressionNode *  expr,
const char *  indent
) 
 

Generate a cPar initialization code that uses the compiled expression classes generated by generateExpressionClasses().
