Member Function Documentation

clear()

void clear ( )

inline

Clear buffer data.

• Assumes buffer is not allocated

free()

void free ( )

inline

Free and uninitialize allocated buffer.

memalloc() [1/2]

T* memalloc ( Size  size, Size  used, Header *&  header  )

inline

Allocate new memory.

• This doesn't modify the current buffer, use to setup replacement buffer

Parameters

size	New buffer size
used	Buffer used value to set
header	Stores pointer to header data [out]

Returns

Pointer to new buffer

memalloc() [2/2]

T* memalloc ( Size  size, Header *&  header  )

inline

Allocate new memory.

• Calls memalloc(Size,Size,Header*&)
• This doesn't modify the current buffer, use to setup replacement buffer
• This adjusts memory allocated using Capacity::init()

Parameters

size	New buffer size
header	Stores pointer to header data [out]

Returns

Pointer to new buffer

memfree()

void memfree ( )

inline

Free buffer memory.

• Assumes buffer is allocated

memrealloc()

T* memrealloc ( Size  size )

inline

Reallocate buffer memory.

• Assumes buffer is already allocated

Parameters

size	New buffer size - must be positive

Returns

Pointer to reallocated list buffer

replace()

T* replace ( T *  newptr, Header *  newheader  )

inline

Free and uninitialize current buffer and replace with new buffer.

Parameters

newptr	New buffer pointer
newheader	New buffer header

Returns

New buffer pointer

Member Data Documentation

header

Header* header
