Simple synchronized implementation of Ringbuffer.
All methods utilize global synchronization.
Characteristics:
| Empty | writePos == readPos | size == 0 |
| Full | writePos == readPos | size == capacity |
Definition at line 51 of file SyncedRingbuffer.java.
| com.jogamp.common.util.SyncedRingbuffer< T >.SyncedRingbuffer | ( | final T[] | copyFrom | ) | throws IllegalArgumentException |
Create a full ring buffer instance w/ the given array's net capacity and content.
Example for a 10 element Integer array:
Integer[] source = new Integer[10]; // fill source with content .. Ringbuffer<Integer> rb = new SyncedRingbuffer<Integer>(source);
isFull() returns true on the newly created full ring buffer.
Implementation will allocate an internal array with size of array copyFrom and copy all elements from array copyFrom into the internal array.
| copyFrom | mandatory source array determining ring buffer's net capacity() and initial content. |
| IllegalArgumentException | if copyFrom is null |

Create an empty ring buffer instance w/ the given net capacity.
Example for a 10 element Integer array:
Ringbuffer<Integer> rb = new SyncedRingbuffer<Integer>(10, Integer[].class);

Implementation will allocate an internal array of size capacity.
