Member Function Documentation

check()

template<class AVariableManager>

bool check ( const Object * p ) const

inlineoverridevirtual

Check if object passes this subexpression of the cut by calling check on the children nodes.

Boolean results are evaluated with the BooleanOperator(AND/OR) the node object.

Parameters

p	pointer to the object, that should be checked.

Implements AbstractBooleanNode< AVariableManager >.

Definition at line 285 of file CutNodes.h.

    {
 
      switch (m_boperator) {
        case BooleanOperator::AND:
          return m_left_bnode->check(p) && m_right_bnode->check(p);
          break;
        case BooleanOperator::OR:
          return m_left_bnode->check(p) || m_right_bnode->check(p);
          break;
        default:
          throw std::runtime_error("BinaryBooleanNode has an invalid BooleanOperator");
      }
      return false;
    }

decompile()

template<class AVariableManager>

std::string decompile ( ) const

inlineoverridevirtual

Decompile Node back to a string.

decompile(compile) should give the same result.

Implements AbstractBooleanNode< AVariableManager >.

Definition at line 315 of file CutNodes.h.

    {
      std::stringstream stringstream;
      stringstream << m_left_bnode->decompile(); // decompile left AbstractBooleanNode
      injectBooleanOperatorToStream(stringstream, m_boperator);
      stringstream << m_right_bnode->decompile(); // decompile right AbstractBooleanNode
 
      return stringstream.str();
    }

print()

template<class AVariableManager>

void print ( ) const

inlineoverridevirtual

Print node.

Implements AbstractBooleanNode< AVariableManager >.

Definition at line 304 of file CutNodes.h.

    {
      m_left_bnode->print();
      injectBooleanOperatorToStream(std::cout, m_boperator);
