Public Member Functions | |
BufferLocked (size_type size, const T &initial_value=T(), bool circular=false) | |
Create a buffer of size size, with preallocated data storage. More... | |
virtual void | data_sample (const T &sample) |
Initializes this buffer with a data sample, such that for dynamical allocated types T, the buffer can reserve place to hold these elements. More... | |
virtual T | data_sample () const |
Reads back a data sample. More... | |
~BufferLocked () | |
Destructor. More... | |
bool | Push (param_t item) |
Write a single value to the buffer. More... | |
size_type | Push (const std::vector< T > &items) |
Write a sequence of values to the buffer. More... | |
bool | Pop (reference_t item) |
Read the oldest value from the buffer. More... | |
size_type | Pop (std::vector< T > &items) |
Read the whole buffer. More... | |
value_t * | PopWithoutRelease () |
Returns a pointer to the first element in the buffer. More... | |
void | Release (value_t *item) |
Releases the pointer. More... | |
size_type | capacity () const |
Returns the maximum number of items that can be stored in the buffer. More... | |
size_type | size () const |
Returns the actual number of items that are stored in the buffer. More... | |
void | clear () |
Clears all contents of this buffer. More... | |
bool | empty () const |
Check if this buffer is empty. More... | |
bool | full () const |
Check if this buffer is full. More... | |
size_type | dropped () const |
Returns the number of dropped samples, because the buffer was full. More... | |

Create a buffer of size size, with preallocated data storage.
size | The number of elements this buffer can hold. |
initial_value | A data sample with which each preallocated data element is initialized. |
circular | Set flag to true to make this buffer circular. If not circular, new values are discarded on full. |
