                throws java.io.IOException
```
    Description copied from interface: StreamSourceChannel
    
    Transfers bytes into the given file from this channel. Using this method in preference to FileChannel.transferFrom(ReadableByteChannel, long, long) may provide a performance advantage on some platforms.
    If the current thread is interrupted when this method is called, it may throw a InterruptedIOException; however, if this exception is thrown, the InterruptedIOException.bytesTransferred field is guaranteed to be 0.
    
    Specified by:
    
    transferTo in interface StreamSourceChannel
    
    Parameters:
    
    position - the position within the file from which the transfer is to begin
    
    count - the number of bytes to be transferred
    
    target - the file to write to
    
    Returns:
    
    the number of bytes (possibly 0) that were actually transferred
    
    Throws:
    
    java.io.IOException - if an I/O error occurs
  - transferTo
```
public long transferTo(long count,
                       java.nio.ByteBuffer throughBuffer,
                       StreamSinkChannel target)
                throws java.io.IOException
```
    Description copied from interface: StreamSourceChannel
    
    Transfers bytes into the given channel target. On some platforms, this may avoid copying bytes between user and kernel space. On other platforms, bytes are passed through the throughBuffer parameter's buffer space. On entry, throughBuffer will be cleared. On exit, the buffer will be flipped for emptying, and may possibly be empty or may contain data. If this method returns a value less than count, then the remaining data in throughBuffer may contain data read from this channel which must be written to target to complete the operation. Note that using a direct buffer may provide an intermediate performance gain on platforms without zero-copy facilities.
    If the current thread is interrupted when this method is called, it may throw a InterruptedIOException; however, if this exception is thrown, the InterruptedIOException.bytesTransferred field is guaranteed to be 0. Note that the return value is the amount of data that was actually transferred to the StreamSinkChannel. The actual amount of data read could be larger than this, and can be calculated by adding the return value and the amount of data left in throughBuffer.
    
    Specified by:
    
    transferTo in interface StreamSourceChannel
    
    Parameters:
    
    count - the number of bytes to be transferred
    
    throughBuffer - the buffer to copy through.
    
    target - the destination to write to
    
    Returns:
    
    the number of bytes (possibly 0) that were actually transferred, or -1 if the end of input was reached
    
    Throws:
    
    java.io.IOException - if an I/O error occurs
  - transferFrom
```
public long transferFrom(FileChannel src,
                         long position,

                  throws java.io.IOException
```
    Description copied from interface: StreamSinkChannel
    
    Transfer bytes into this channel from the given file. Using this method in preference to FileChannel.transferTo(long, long, WritableByteChannel) may provide a performance advantage on some platforms.

    Description copied from interface: SuspendableWriteChannel
    
    Indicate that writing is complete for this channel. Further attempts to write data to this channel after this method is invoked will result in an exception. If this method was already called, calling this method again will have no additional effect. After this method is called, any remaining data still must be flushed out via the SuspendableWriteChannel.flush() method; once this is done, if the read side of the channel was shut down, the channel will automatically close.

    Description copied from interface: SuspendableWriteChannel
    
    Flush any waiting partial send or write. If there is no data to flush, or if the flush completed successfully, this method will return true. If there is data to flush which cannot be immediately written, this method will return false. If this method returns true after SuspendableWriteChannel.shutdownWrites() was called on this channel, the write listener will no longer be invoked on this channel. If this is case and additionally this is a write-only channel or the read side was previously shut down, then the channel will automatically be closed.
    
    Specified by:
    
    flush in interface SuspendableWriteChannel
    
    Returns:

```
public int writeFinal(java.nio.ByteBuffer src)
               throws java.io.IOException
```
    Description copied from interface: StreamSinkChannel
    
    Writes some data to the channel, with the same semantics as WritableByteChannel.write(java.nio.ByteBuffer). If all the data is written out then the channel will have its writes shutdown. Semantically this method is equivalent to: int rem = src.remaining(); int written = channel.write(src); if(written == rem) { channel.shutdownWrites() } If an exception is thrown the caller is still responsible for closing the channel.
    
    Specified by:

public long writeFinal(java.nio.ByteBuffer[] srcs,
                       int offset,
                       int length)
                throws java.io.IOException
```
    Description copied from interface: StreamSinkChannel
    
    Writes some data to the channel, with the same semantics as GatheringByteChannel.write(java.nio.ByteBuffer[], int, int). If all the data is written out then the channel will have its writes shutdown. If an exception is thrown the caller is still responsible for closing the channel.
    
    Specified by:
    
    writeFinal in interface StreamSinkChannel
    
    Parameters:
    
    srcs - The buffers from which bytes are to be retrieved
    
    offset - The offset within the buffer array of the first buffer from which bytes are to be retrieved; must be non-negative and no larger than srcs.length
    
    length - The maximum number of buffers to be accessed; must be non-negative and no larger than srcs.length - offset
    
    Returns:
    
    The amount of data that was actually written
    
    Throws:
    
    java.io.IOException

```
public void close()
           throws java.io.IOException
```
    Description copied from interface: CloseableChannel
    
    Close this channel. When a channel is closed, its close listener is invoked. Invoking this method more than once has no additional effect.
    
    Specified by:
    
    close in interface java.io.Closeable
    
    Specified by:
    
    close in interface java.lang.AutoCloseable

    close in interface java.nio.channels.Channel
    
    Specified by:
    
    close in interface java.nio.channels.InterruptibleChannel
    
    Specified by:
    
    close in interface CloseableChannel
    
    Specified by:
    
    close in interface SuspendableWriteChannel
    
    Throws:
    
    java.io.IOException - if the close failed
  - isOpen
```
public boolean isOpen()
```
    Description copied from interface: SuspendableWriteChannel
    
    Determine whether this channel is open. This method will return false if all directions are shut down, even if there is unflushed write data pending.
    
    Specified by:
    
    isOpen in interface java.nio.channels.Channel
    
    Specified by:
    
    isOpen in interface SuspendableWriteChannel
    
    Returns:
    
    true if the channel is open, false otherwise
  - supportsOption
```
public boolean supportsOption(Option<?> option)
```
    Description copied from interface: Configurable
    
    Determine whether an option is supported on this channel.
    
    Specified by:
    
    supportsOption in interface Configurable
    
    Parameters:
    
    option - the option
    
    Returns:
    
    true if it is supported
  - getOption
```
public <T> T getOption(Option<T> option)
                throws java.io.IOException
```
    Description copied from interface: Configurable
    
    Get the value of a channel option.
    
    Specified by:
    
    getOption in interface Configurable
    
    Type Parameters:
    
    T - the type of the option value
    
    Parameters:
    
    option - the option to get
    
    Returns:
    
    the value of the option, or null if it is not set
    
    Throws:
    
    java.io.IOException - if an I/O error occurred when reading the option
  - setOption
```
public <T> T setOption(Option<T> option,
                       T value)
                throws java.lang.IllegalArgumentException,
                       java.io.IOException
```
    Description copied from interface: Configurable
    
    Set an option for this channel. Unsupported options are ignored.
    
    Specified by:
    
    setOption in interface Configurable
    
    Type Parameters:
    
    T - the type of the option value
    
    Parameters:
    
    option - the option to set
    
    value - the value of the option to set
    
    Returns:
