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 children nodes.

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

Parameters
ppointer to the object, that should be checked.

Implements AbstractBooleanNode< AVariableManager >.

Definition at line 285 of file CutNodes.h.

288 switch (m_boperator) {
289 case BooleanOperator::AND:
290 return m_left_bnode->check(p) && m_right_bnode->check(p);
291 break;
292 case BooleanOperator::OR:
293 return m_left_bnode->check(p) || m_right_bnode->check(p);
294 break;
295 default:
296 throw std::runtime_error("BinaryBooleanNode has an invalid BooleanOperator");
297 }
298 return false;
299 }

◆ decompile()

std::string decompile ( ) const
inlineoverridevirtual

Decompile Node back to a string.

decompile(compile) should give the same result.

Implements AbstractBooleanNode< AVariableManager >.
