A number of the existing basic data structures already have <tt>SizeOf{In,Ex}cludingThis</tt> functions, e.g. <tt>nsTArray</tt> and <tt>nsTHashtable</tt>. <tt>nsTHashtable</tt>'s functions take an extra argument which is a pointer to a function that measures the memory usage of any structures pointed to by entries in the hash table. | |||
Sometimes you may need variations on the above forms. For example, if you have a function that just measures one member <tt>Foo</tt> of an object, it might be called <tt>SizeOfFoo</tt>. Try to make the names descriptive enough that it's clear what's being measured. | Sometimes you may need variations on the above forms.
