template<typename T >
bool vec< T, va_heap, vl_ptr >::contains ( const T & search) const

exactly like vec::reserve, but the internal vector is
unconditionally allocated from scratch.  The old one, if it
existed, is lost.

vector.  If T has non-trivial destructor, this method just pops
last element and returns void.   

◆ qsort()

template<typename T >
void vec< T, va_heap, vl_ptr >::qsort ( int(*)(const void *, const void *) cmp)

References va_heap::release().

◆ reserve()

template<typename T >
bool vec< T, va_heap, vl_ptr >::reserve ( unsigned ,
bool = false CXX_MEM_STAT_INFO )
inline
Ensure that the vector has at least RESERVE slots available (if
EXACT is false), or exactly RESERVE slots available (if EXACT is
true).

This may create additional headroom if EXACT is false.

Note that this can cause the embedded vector to be reallocated.
Returns true iff reallocation actually occurred.   

References ggc_alloc(), NULL, PASS_MEM_STAT, va_heap::reserve(), and vec_copy_construct().

◆ reserve_exact()

template<typename T >

embedded vector to be reallocated.  Returns true iff reallocation
actually occurred.

◆ safe_grow()

template<typename T >
void vec< T, va_heap, vl_ptr >::safe_grow ( unsigned ,
bool = false CXX_MEM_STAT_INFO )
inline
Grow the vector to a specific length.  LEN must be as long or
longer than the current length.  The new elements are
uninitialized.  Reallocate the internal vector, if needed.
