Question

I’m new to Java programming. I have several questions about how to implement RingFiFoBuffer:

1. Can I store big XML files into this buffer? If yes how big?
2. Can several threads insert/delete/fetch records from the RingBuffer simultaneously?
3. How many records can I store?
4. Is there any tutorial that I can see how to write the code.

I only found http://commons.apache.org/collections/apidocs/org/apache/commons/collections/buffer/CircularFifoBuffer.html

Answer 1

Question 1 and 3: That is only limited by the memory you assign to the Java process that executes your program.

Qestion 2: Accessing a Collection like the referenced CircularFifoBuffer usually requires to “synchronize” them. The linked JavaDoc already contains the code for synchronizing it:

Buffer fifo = BufferUtils.synchronizedBuffer(new CircularFifoBuffer());
