Member Function Documentation

void add ( HostBuffer *  buffer, uint64_t  size  )

inline

Allocate a buffer of the specified size and add it to the register.

bool isFull ( ) const

inline

Return true is all the memory in this pool is in use.

Pool& operator= ( const Pool &  )

delete

Disallow copy assignment operation.

Pool& operator= ( const Pool &&  )

delete

Disallow move assignment operation.

void remove ( HostBuffer *  buffer )

inline

Remove the specified buffer from the register.

void replace ( HostBuffer *  buffer1, HostBuffer *  buffer2  )
