Member Function Documentation

◆ allocate()

pointer allocate ( size_type  n,
const void *  = nullptr 
)
inline

Attempts to allocate a block of storage with a size large enough to contain n elements of member type value_type, and returns a pointer to the first element.

Definition at line 69 of file allocator.hpp.

Referenced by thrill::mem::mm_new().

◆ deallocate()

void deallocate ( pointer  p,
size_type  n 
) const
inlinenoexcept

Releases a block of storage previously allocated with member allocate and not yet released.

Definition at line 97 of file allocator.hpp.

◆ operator!=()

bool operator!= ( const Allocator< Other > &  other) const
inlinenoexcept

Compare to another allocator of same type.

Member Data Documentation

◆ debug

constexpr bool debug = false
staticprivate

Definition at line 33 of file allocator.hpp.

◆ manager_

Manager* manager_

pointer to common Manager object. If we use a reference here, then the allocator cannot be default move/assigned anymore.
