Detailed Description

template<class AVariableManager>
class Belle2::UnaryBooleanNode< AVariableManager >

Nodeclass with a single AbstractBooleanNode as child.

Class for constructing Node objects of boost::python::tuple NodeFactory is a friend to all Node classes, in order to use their private Constructor.

check() returns the negated result of the child node if m_negation is true.

Parameters

node	(const boost::python::tuple&) tuple containing a boolean node
negation	(bool): flag if check output of m_bnode should be returned negated
bracketized	(bool): flag if cut substring was in brackets, used for preserving brackets when decompling to a string.

Member Function Documentation

check()

bool check ( const Object *  p ) const

inlineoverridevirtual

Check if Object passes this subexpression of the cut by calling check on the child node.

Parameters

p	pointer to the object, that should be checked.

Implements AbstractBooleanNode< AVariableManager >.

Definition at line 208 of file CutNodes.h.

    {
      // Return negated result of child node evaluation if m_negation is true.
      if (m_negation) return !m_bnode->check(p);
 
      return m_bnode->check(p);
    }

decompile()

std::string decompile ( ) const

inlineoverridevirtual

Decompile Node back to a string.

Decompile(compile) should give the same result. brackets and negation keywords are added if m_bracketized, m_negation are set to true.

Implements AbstractBooleanNode< AVariableManager >.

Definition at line 232 of file CutNodes.h.

    {
      std::stringstream stringstream;
      if (m_negation) stringstream << "not "; // Add negation keyword
 
      if (m_bracketized) stringstream << "["; // Add opening bracket
      stringstream << m_bnode->decompile();
      if (m_bracketized) stringstream << "]"; // Add closing bracket
 
      return stringstream.str();
    }

print()

void print ( ) const

inlineoverridevirtual

Print node brackets and negation keywords are added if m_bracketized, m_negation are set to true.

Implements AbstractBooleanNode< AVariableManager >.

Definition at line 220 of file CutNodes.h.

    {
      if (m_negation) std::cout << "not ";
      if (m_bracketized) std::cout << "[";
