◆ decompile()

std::string decompile ( ) const
inlineoverridevirtual

Decompile Node back to a string.

decompile(compile) should give the same result.

Implements AbstractExpressionNode< AVariableManager >.

1047 return fullname;
1048 }

◆ evaluate()

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

evaluate m_var with p and return the result

Parameters
ppointer to the object, for which m_var should be evaluated.

Implements AbstractExpressionNode< AVariableManager >.
