Constructor Details

SourceChannel

protected SourceChannel(SelectorProvider provider)

Constructs a new instance of this class.

Parameters:

provider - The selector provider

Method Details

validOps

public final int validOps()

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

Pipe-source channels only support reading, so this method returns SelectionKey.OP_READ.

Specified by:

validOps in class SelectableChannel

Returns:

The valid-operation set
