Protected Constructors

protected SinkChannel (SelectorProvider provider)

Initializes a new instance of this class.

Parameters

provider	The selector provider

Public Methods

public final int validOps ()

Returns an operation set identifying this channel's supported operations.

Pipe-sink channels only support writing, so this method returns SelectionKey.OP_WRITE.

Returns

• The valid-operation set
