Example 1 with MutableLong

use of libcore.util.MutableLong in project j2objc by google.

the class FileChannelImpl method transferTo.

public long transferTo(long position, long count, WritableByteChannel target) throws IOException {
    checkOpen();
    if (!target.isOpen()) {
        throw new ClosedChannelException();
    }
    checkReadable();
    if (target instanceof FileChannelImpl) {
        ((FileChannelImpl) target).checkWritable();
    }
    if (position < 0 || count < 0) {
        throw new IllegalArgumentException("position=" + position + " count=" + count);
    }
    if (count == 0 || position >= size()) {
