List of selectedKeys() Examples

Examples of selectedKeys()

java.nio.channels.Selector.selectedKeys()
Returns this selector's selected-key set.
Keys may be removed from, but not directly added to, the selected-key set. Any attempt to add an object to the key set will cause an {@link UnsupportedOperationException} to be thrown.
The selected-key set is not thread-safe.
@return This selector's selected-key set @throws ClosedSelectorException If this selector is closed
