Detailed Description

template<class AVariableManager>
class Belle2::UnaryExpressionNode< AVariableManager >

UnaryExpressionNode Node class with a single expression node as child.

Used for unary minus signs and parenthesis conservation on decompiling cuts.

Definition at line 653 of file CutNodes.h.

Constructor & Destructor Documentation

UnaryExpressionNode()

UnaryExpressionNode ( Nodetuple  node, bool  unary_minus, bool  parenthesized  )

inlineexplicitprivate

Constructor.

Parameters

node	(const boost::python::tuple&): tuple containing an expression node
unary_minus	(bool): flag indicating if evaluate result should be multiplied by -1
parenthesized	(bool): flag indicating if expression in cut was in parenthesis

Definition at line 711 of file CutNodes.h.

Member Function Documentation

decompile()

std::string decompile ( ) const

inlineoverridevirtual

Decompile Node back to a string.

decompile(compile) should give the same result.

Implements AbstractExpressionNode< AVariableManager >.

Definition at line 689 of file CutNodes.h.

evaluate()

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

inlineoverridevirtual

Evaluation of the child nodes and return result as a variant<double, int, bool> return negative result if m_unary_minus true.

Parameters

p	pointer to the object, that should be checked.

Implements AbstractExpressionNode< AVariableManager >.
