Behaviour During Construction and Destruction
Languages differ in their behaviour while the constructor or destructor of an object is running. For some languages, notably C++, the virtual dispatching mechanism has different semantics during construction and destruction of an object. While it is recommended that virtual function calls in constructors should be avoided for C++, in some other languages, for example C# and Java, the derived implementation can be called during construction and design patterns such as the Abstract Factory Pattern actively promote this usage in languages supporting the ability.

Famous quotes containing the words behaviour, construction and/or destruction:
“When we read of human beings behaving in certain ways, with the approval of the author, who gives his benediction to this behaviour by his attitude towards the result of the behaviour arranged by himself, we can be influenced towards behaving in the same way.”
—T.S. (Thomas Stearns)
“Striving toward a goal puts a more pleasing construction on our advance toward death.”
—Mason Cooley (b. 1927)
“Though castles topple on their warder’s heads,
Though palaces and pyramids do slope
Their heads to their foundations; though the treasure
Of nature’s germens tumble all together,
Even till destruction sicken—answer me
To what I ask you.”
—William Shakespeare (1564–1616)
