Overrides org.xnio.conduits.AbstractStreamSinkConduit.transferFrom.

Implements org.xnio.conduits.StreamSinkConduit.transferFrom.

Doc from org.xnio.conduits.StreamSinkConduit.transferFrom.

Transfer bytes into this conduit from the given file.

Parameters
src:FileChannel

the file to read from

position:long

the position within the file from which the transfer is to begin

count:long

the number of bytes to be transferred

Returns:long

the number of bytes (possibly 0) that were actually transferred

public long transferFrom(final StreamSourceChannel source, final long count, final ByteBuffer throughBuffer) throws IOException

Overrides org.xnio.conduits.AbstractStreamSinkConduit.transferFrom.

Implements org.xnio.conduits.StreamSinkConduit.transferFrom.

Doc from org.xnio.conduits.StreamSinkConduit.transferFrom.

Transfers bytes from the given channel source. On entry, throughBuffer will be cleared. On exit, the buffer will be flipped for emptying, and may 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 source which must be written to this channel to complete the operation.

Parameters
source:StreamSourceChannel

the source to read from

count:long

the number of bytes to be transferred

throughBuffer:ByteBuffer

the buffer to copy through.

Returns:long

the number of bytes (possibly 0) that were actually transferred, or -1 if the end of input was reached

Overrides org.xnio.conduits.AbstractStreamSinkConduit.writeFinal.

Implements org.xnio.conduits.StreamSinkConduit.writeFinal.

Doc from org.xnio.conduits.StreamSinkConduit.writeFinal.

Writes some data to the conduit, with the same semantics as write(java.nio.ByteBuffer). If all the data is written out then the conduit will have its writes terminated. Semantically this method is equivalent to: int rem = src.remaining(); int written = conduit.write(src); if(written == rem) { conduit.terminateWrites() }

Parameters
src:ByteBuffer

The data to write

Returns:int

The amount of data that was actually written.

Implements org.xnio.conduits.StreamSinkConduit.writeFinal.

Doc from org.xnio.conduits.StreamSinkConduit.writeFinal.

Writes some data to the conduit, with the same semantics as write(java.nio.ByteBuffer[], int, int). If all the data is written out then the conduit will have its writes terminated.

Parameters
srcs:ByteBuffer[]

The buffers from which bytes are to be retrieved

offset:int

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:int

The maximum number of buffers to be accessed; must be non-negative and no larger than srcs.length - offset

Returns:long
