Public Types

typedef int(*) comparison_type_fn_t (const T *, const T *)
 Runs the C qsort() routine over the vector, as long as the vector is big enough.

void insert (int slot, T *elem, bool autofree)
 Insert an element into a slot, and shifts the others to the right.
void prepend (T *elem, bool autofree)
 Prepends an element to the start of the vector.
void append (T *elem, bool autofree)
 Appends an element to the end of the vector.
void qsort (comparison_type_fn_t comparator)
int count () const
 Returns the number of elements actually stored in the vector.

Member Typedef Documentation

template<class T>
typedef int(*) WvVector< T >::comparison_type_fn_t(const T *, const T *)

Runs the C qsort() routine over the vector, as long as the vector is big enough.

It uses comparator like qsort() does to figure out the order of the operators.

Definition at line 341 of file wvvector.h.


Member Function Documentation

void WvVectorBase::set_capacity ( int  newslots  )  [inherited]

Adjusts the capacity of the vector.

If the new capacity is greater than the old one, extends the array size without actually filling in any elements.
