Member Function Documentation

construct()

template<class T >

static void OdMemoryAllocator< T >::construct ( T *  pElement, const T &  value = T()  )

inlinestatic

This function constructs an element.

Parameters

pElement	[out] Receives the element.
value	[in] Value for the element.

Definition at line 96 of file OdArray.h.

constructn() [1/3]

template<class T >

static void OdMemoryAllocator< T >::constructn ( T *  pDestination, const T *  pSource, size_type  numElements  )

inlinestatic

This function constructs an array of elements.

Parameters

pDestination	[in] Pointer to the destination.
pSource	[in] Pointer to the source.
numElements	[in] Number of elements.

Remarks

When called with two arguments, this function does nothing but return.

Definition at line 134 of file OdArray.h.

constructn() [2/3]

template<class T >

static void OdMemoryAllocator< T >::constructn ( T *  pDestination, size_type  numElements  )

inlinestatic

This function constructs an array of elements.

Parameters

T*	[in] Pointer to the destination.
size_type	[in] Number of elements.

Remarks

When called with two arguments, this function does nothing but return.

Definition at line 153 of file OdArray.h.

constructn() [3/3]

template<class T >

static void OdMemoryAllocator< T >::constructn ( T *  pDestination, size_type  numElements, const T &  value  )

inlinestatic

This function constructs an array of elements.

Parameters

pDestination	[in] Pointer to the destination.
numElements	[in] Number of elements.
value	[in] Value for the elements.

Remarks

When called with two arguments, this function does nothing but return.

Definition at line 113 of file OdArray.h.

copy()

template<class T >

static void OdMemoryAllocator< T >::copy ( T *  pDestination, const T *  pSource, size_type  numElements  )

inlinestatic

This function copies the specified number of elements from source to destination.

Parameters

pDestination	[in] Pointer to the destination.
pSource	[in] Pointer to the source.
numElements	[in] Number of elements.

Remarks

If the source and destination regions overlap, the behavior of this function is undefined. Use move() to handle overlapping regions.

Definition at line 62 of file OdArray.h.

destroy() [1/2]

template<class T >

static void OdMemoryAllocator< T >::destroy ( T *  )

inlinestatic

Destroys the specified element or elements.

Remarks

This function does nothing but return.

Definition at line 166 of file OdArray.h.

destroy() [2/2]

template<class T >

static void OdMemoryAllocator< T >::destroy ( T *  , size_type    )

inlinestatic

Destroys the specified element or elements.

Remarks

This function does nothing but return.

Definition at line 177 of file OdArray.h.

move()

template<class T >

static void OdMemoryAllocator< T >::move ( T *  pDestination, const T *  pSource, size_type  numElements  )

inlinestatic

This function copies the specified number of elements from source to destination.

Parameters

pDestination	[in] Pointer to the destination.
pSource	[in] Pointer to the source.
numElements	[in] Number of elements.

Remarks

If the source and destination regions overlap, move copies the overlapping region before it is overwritten.

Use copy() to handle non-overlapping regions.

Definition at line 83 of file OdArray.h.

useRealloc()

template<class T >

static bool OdMemoryAllocator< T >::useRealloc ( )

inlinestatic

Returns true if and only if odrxRealloc can be used to resize an array.

Remarks

This function always returns true.
