Constructor & Destructor Documentation

Pool ( uint64_t  size = 0,
void *  data = nullptr 
)
inline

External memory ctor.

~Pool ( )
inline

Custom destructor.

Pool ( const Pool )
delete

Disallow copy-construction.

Pool ( const Pool &&  )
delete

Disallow move-construction.

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 
)
inline

Replaces buffer1 with buffer2 in the register.

void reset ( )
inline

Reset the register and all its buffers.

void resize ( uint64_t  size,
void *  data = nullptr
