Member Function Documentation

decompile()

template<class AVariableManager, typename T>

std::string decompile ( ) const

inlineoverridevirtual

Decompile Node back to a string.

decompile(compile) should give the same result.

Implements AbstractExpressionNode< AVariableManager >.

Definition at line 923 of file CutNodes.h.

    {
      std::stringstream stringstream;
      stringstream << std::boolalpha;
      stringstream << m_value;
      return stringstream.str();
    }

evaluate()

template<class AVariableManager, typename T>

AVariableManager::VarVariant evaluate ( const Object * p ) const

inlineoverridevirtual

return m_value as a variant<double, int, bool>

Parameters

p	pointer to the object, that should be checked. Not needed here since we always return the constant m_value.

Implements AbstractExpressionNode< AVariableManager >.

Definition at line 904 of file CutNodes.h.

    {
      (void)p;
      typename AVariableManager::VarVariant ret{m_value};
      return ret;
    }

print()

template<class AVariableManager, typename T>

void print ( ) const

inlineoverridevirtual

Print node.

Implements AbstractExpressionNode< AVariableManager >.

Definition at line 913 of file CutNodes.h.

    {
      std::cout << std::boolalpha;
      std::cout << m_value;
