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
ppointer to the object, that should be checked.

Implements AbstractBooleanNode< AVariableManager >.

Definition at line 208 of file CutNodes.h.

209 {
210 // Return negated result of child node evaluation if m_negation is true.
211 if (m_negation) return !m_bnode->check(p);
212
213 return m_bnode->check(p);
214 }

◆ 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.

233 {
234 std::stringstream stringstream;
235 if (m_negation) stringstream << "not "; // Add negation keyword
236
237 if (m_bracketized) stringstream << "["; // Add opening bracket
238 stringstream << m_bnode->decompile();
239 if (m_bracketized) stringstream << "]"; // Add closing bracket
240
241 return stringstream.str();
242 }

◆ 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.

221 {
222 if (m_negation) std::cout << "not ";
223 if (m_bracketized) std::cout << "[";
