CyclicBuffer (int maxSize) | |
Instantiate a new CyclicBuffer of at most maxSize events. | |
~CyclicBuffer () | |
void | add (const spi::LoggingEventPtr &event) |
Add an event as the last event in the buffer. | |
spi::LoggingEventPtr | get (int i) |
Get the ith oldest event currently in the buffer. | |
int | getMaxSize () const |
spi::LoggingEventPtr | get () |
Get the oldest (first) element in the buffer. | |
int | length () const |
Get the number of elements in the buffer. | |
void | resize (int newSize) |
Resize the cyclic buffer to newSize . |
This buffer gives read access to any element in the buffer not just the first or last element.
CyclicBuffer | ( | int | maxSize | ) |
Instantiate a new CyclicBuffer of at most maxSize
events.
The maxSize
argument must a positive integer.
maxSize | The maximum number of elements in the buffer. |
IllegalArgumentException | if maxSize is negative. |
~CyclicBuffer | ( | ) |
void add | ( | const spi::LoggingEventPtr & | event | ) |
Add an event
as the last event in the buffer.
spi::LoggingEventPtr get | ( | ) |
Get the oldest (first) element in the buffer.
The oldest element is removed from the buffer.
spi::LoggingEventPtr get | ( | int | i | ) |
Get the ith oldest event currently in the buffer.
If i is outside the range 0 to the number of elements currently in the buffer, then null
is returned.
int getMaxSize | ( | ) | const [inline] |
int length | ( | ) | const [inline] |
Get the number of elements in the buffer.
This number is guaranteed to be in the range 0 to maxSize
(inclusive).
void resize | ( | int | newSize | ) |
