Examples with Runtime jnr.ffi.Runtime used on opensource projects

Example 6 with Runtime

use of jnr.ffi.Runtime in project alluxio by Alluxio.

the class AlluxioFuseFileSystemTest method read.

@Test
public void read() throws Exception {
    // mocks set-up
    AlluxioURI expectedPath = BASE_EXPECTED_URI.join("/foo/bar");
    setUpOpenMock(expectedPath);
    FileInStream fakeInStream = mock(FileInStream.class);
    when(fakeInStream.read(any(byte[].class), anyInt(), anyInt())).then((Answer<Integer>) invocationOnMock -> {
        byte[] myDest = (byte[]) invocationOnMock.getArguments()[0];
        for (byte i = 0; i < 4; i++) {
            myDest[i] = i;
        }
        return 4;
    });
    when(fakeInStream.remaining()).thenReturn(4L);
    when(mFileSystem.openFile(expectedPath)).thenReturn(fakeInStream);
    mFileInfo.flags.set(O_RDONLY.intValue());
    // prepare something to read to it
    Runtime r = Runtime.getSystemRuntime();
    Pointer ptr = r.getMemoryManager().allocateTemporary(4, true);
    // actual test
    mFuseFs.open("/foo/bar", mFileInfo);
    mFuseFs.read("/foo/bar", ptr, 4, 0, mFileInfo);

    ptr.get(0, dst, 0, 4);
    final byte[] expected = new byte[] { 0, 1, 2, 3 };
    assertArrayEquals("Source and dst data should be equal", expected, dst);
}

            return 4L;
        } else {
            return 3L;
        }
    });
    when(mFileSystem.openFile(expectedPath)).thenReturn(fakeInStream);
