Detailed Description

template<class AVariableManager>
class Belle2::BinaryRelationalNode< AVariableManager >

BooleanNode which has two AbstractExpressionNodes nodes and a ComparisonOperator.

Check() evaluates the children nodes and compares the results with the specified operator.

Constructor & Destructor Documentation

BinaryRelationalNode()

BinaryRelationalNode ( Nodetuple  left_node, Nodetuple  right_node, ComparisonOperator  coperator  )

inlineexplicitprivate

Constructor.

Parameters

left_node	(const boost::python::tuple&): tuple containing an expression node
right_node	(const boost::python::tuple&): tuple containing an expression node
coperator	(ComparisonOperator): comparison operator enum value

Member Function Documentation

check()

bool check ( const Object *  p ) const

inlineoverridevirtual

Evaluate the Expression children nodes which yield std::variant values.

variant data types cannot be compared in relational expressions, every data type combination has to be considered.

Parameters

p	pointer to the object, that should be checked. returns the boolean result of the relational expression.

Implements AbstractBooleanNode< AVariableManager >.

Definition at line 439 of file CutNodes.h.

decompile()

std::string decompile ( ) const

inlineoverridevirtual

Decompile Node back to a string.

decompile(compile) should give the same result.

Implements AbstractBooleanNode< AVariableManager >.
