Member Function Documentation

template<typename T >

pointer Hypertable::AllocatorBase< T >::address ( reference  x ) const

inline

Returns a pointer to an object of type T.

Parameters

x	A reference to the object

Returns

The address of x (of type T*)

Definition at line 93 of file Allocator.h.

template<typename T >

const_pointer Hypertable::AllocatorBase< T >::address ( const_reference  x ) const

inline

Returns a const pointer to an object of type T.

Parameters

x	A reference to the object

Returns

The address of x (of type const T*)

Definition at line 100 of file Allocator.h.

template<typename T >

template<class U , class... Args>

void Hypertable::AllocatorBase< T >::construct ( U *  p, Args &&...  args  )

inline

Creates a new object instance using placement new and the copy constructor.

Parameters

p	A pointer to the memory area where the new object will be constructed
args	Arguments

Definition at line 121 of file Allocator.h.

template<typename T >

void Hypertable::AllocatorBase< T >::construct ( pointer  p )

inline

Creates a new object instance using placement new and the default constructor.

Parameters

p	A pointer to the memory area where the new object will be constructed
