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

Overrides org.xnio.conduits.AbstractStreamSourceConduit.read.

Implements org.xnio.conduits.StreamSourceConduit.read.

Doc from org.xnio.conduits.StreamSourceConduit.read.

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

Parameters
dsts:ByteBuffer[]

the buffers to fill with data from the conduit

offset:int

the offset into the buffer array

length:int

the number of buffers to fill

Returns:long

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

Implements org.xnio.conduits.StreamSourceConduit.read.

Doc from org.xnio.conduits.StreamSourceConduit.read.

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

Parameters
dst:ByteBuffer

the buffer to fill with data from the conduit

Returns:int

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

Overrides org.xnio.conduits.AbstractStreamSourceConduit.transferTo.

Implements org.xnio.conduits.StreamSourceConduit.transferTo.

Doc from org.xnio.conduits.StreamSourceConduit.transferTo.

Transfers bytes into the given file from this channel.

Parameters
position:long

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

count:long

the number of bytes to be transferred

target:FileChannel

the file to write to

Returns:long

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

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

Overrides org.xnio.conduits.AbstractStreamSourceConduit.transferTo.

Implements org.xnio.conduits.StreamSourceConduit.transferTo.

Doc from org.xnio.conduits.StreamSourceConduit.transferTo.

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.

Parameters
count:long

the number of bytes to be transferred

throughBuffer:ByteBuffer

the buffer to copy through.

target:StreamSinkChannel

the destination to write to

Returns:long

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

IOException:
