Detailed Description

template<class T, class Tag>
class Givaro::ArrayAllocatort< T, Tag >

ArrayAllocator: class for allocation of arrays.

Specialization: for Array0Tag.

Should have

• allocate(size_n)
• resize(size_n)
• destroy

Member Function Documentation

allocate()

void allocate ( size_t  s )

inlineinherited

Allocation of an array of s Elements.

if refcount>1 then it is always a creation of new array

reallocate()

void reallocate ( size_t  s )

inlineinherited

Reallocation of an array of s Elements.

if refcount>1 then it is always a creation of new array + recopy

copy()

Array0< T > & copy ( const Self_t &  src )

inlineinherited

Physical copy operator.

reallocate dest of the same size as src (if necessary) and apply GivaroCopyItem<Array<T>,T> on each Element. This class can be specialized. Return dest (i.e, *this).

Field Documentation

_size

size_t _size

protectedinherited

actual size of the array.

If ==0 then _psz=_d=_cnt=0
