Example 11 with StreamByteBuffer

use of org.grails.buffer.StreamByteBuffer in project grails-core by grails.

the class StreamByteBufferTest method bufferTest2.

private void bufferTest2(int streamByteBufferSize, int testBufferSize) throws IOException {
    StreamByteBuffer streamBuf = new StreamByteBuffer(streamByteBufferSize);
    OutputStream output = streamBuf.getOutputStream();
    for (int i = 0; i < testBufferSize; i++) {
        output.write(i % (Byte.MAX_VALUE * 2));
    }
    output.close();
    InputStream input = streamBuf.getInputStream();
    assertEquals(testBufferSize, input.available());
    for (int i = 0; i < testBufferSize; i++) {
        assertEquals((i % (Byte.MAX_VALUE * 2)), input.read());
    }
    assertEquals(-1, input.read());
