    return byteBuffer;
}

Example 93 with OutputStream

use of java.io.OutputStream in project grails-core by grails.

the class StreamByteBufferTest method bufferTest.

private void bufferTest(int streamByteBufferSize, int testBufferSize) throws IOException {

    OutputStream output = streamBuf.getOutputStream();
    for (int i = 0; i < testBufferSize; i++) {
        output.write(i % (Byte.MAX_VALUE * 2));
    }
    output.close();
    byte[] buffer = new byte[testBufferSize];
    InputStream input = streamBuf.getInputStream();
    assertEquals(testBufferSize, input.available());
    int readBytes = input.read(buffer);
    assertEquals(readBytes, testBufferSize);
    for (int i = 0; i < buffer.length; i++) {
        assertEquals((byte) (i % (Byte.MAX_VALUE * 2)), buffer[i]);
    }
    assertEquals(-1, input.read());
    assertEquals(-1, input.read());
    assertEquals(-1, input.read());
    assertEquals(-1, input.read());
    input.close();
}

Example 94 with OutputStream

use of java.io.OutputStream in project gradle by gradle.

    final AtomicInteger callCounter = new AtomicInteger(0);
    Action<OutputStream> fileAction = new Action<OutputStream>() {

        @Override
        public void execute(OutputStream outputStream) {

    assertFalse(fileTreeAdapter.contains(rootDir.file("file2.txt")));
    assertEquals(0, callCounter.get());
}

    final AtomicReference<String> currentContentReference = new AtomicReference<String>("content");
    tree.add("path/file.txt", new Action<OutputStream>() {

        @Override
        public void execute(OutputStream outputStream) {
