Method Detail

newStream

public TreeNodeStream newStream(java.lang.Object t)

Description copied from class: TestTreeNodeStream

Build new stream; let's us override to test other streams.

Overrides:

newStream in class TestTreeNodeStream

testBufferOverflow

public void testBufferOverflow()
                        throws java.lang.Exception

Throws:

java.lang.Exception

testBufferWrap

public void testBufferWrap()
                    throws java.lang.Exception

Test what happens when tail hits the end of the buffer, but there is more room left. Specifically that would mean that head is not at 0 but has advanced somewhere to the middle of the lookahead buffer. Use consume() to advance N nodes into lookahead. Then use LT() to load at least INITIAL_LOOKAHEAD_BUFFER_SIZE-N nodes so the buffer has to wrap.

Throws:

java.lang.Exception
