Constructor Detail

BrokenStreamSourceConduit

public BrokenStreamSourceConduit(StreamSourceConduit next,
                                 IOException exception)

Method Detail

transferTo

public long transferTo(long position,
                       long count,
                       FileChannel target)
                throws IOException

Description copied from interface: StreamSourceConduit

Transfers bytes into the given file from this channel.

Specified by:

transferTo in interface StreamSourceConduit

Overrides:

transferTo in class AbstractStreamSourceConduit<StreamSourceConduit>

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:

IOException - if an I/O error occurs

transferTo

public long transferTo(long count,
                       ByteBuffer throughBuffer,
                       StreamSinkChannel target)
                throws IOException

Description copied from interface: StreamSourceConduit

Transfers bytes into the given channel target. 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.

Specified by:

transferTo in interface StreamSourceConduit

Overrides:

transferTo in class AbstractStreamSourceConduit<StreamSourceConduit>

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:

IOException - if an I/O error occurs

read

public long read(ByteBuffer[] dsts,
                 int offset,
                 int length)
          throws IOException

Description copied from interface: StreamSourceConduit

Read a sequence of bytes from this conduit to the given buffers.

Specified by:

read in interface StreamSourceConduit

Overrides:

read in class AbstractStreamSourceConduit<StreamSourceConduit>

offset - the offset into the buffer array

length - the number of buffers to fill

Returns:

the number of bytes (possibly 0) that were actually transferred, or -1 if the end of input was reached or this conduit's SourceConduit.terminateReads() method was previously called

Throws:

IOException - if an error occurs

read

public int read(ByteBuffer dst)
         throws IOException

Description copied from interface: StreamSourceConduit

Read a sequence of bytes from this conduit to the given buffer.

Specified by:

read in interface StreamSourceConduit

Overrides:

read in class AbstractStreamSourceConduit<StreamSourceConduit>

Returns:

the number of bytes (possibly 0) that were actually transferred, or -1 if the end of input was reached or this conduit's SourceConduit.terminateReads() method was previously called

Throws:

IOException - if an error occurs
