jdk.nio.channels.spi.AbstractSelector
Base implementation class for selectors.
This class encapsulates the low-level machinery required to implement the interruption of selection operations. A concrete selector class must invoke the begin and end methods before and after, respectively, invoking an I/O operation that might block indefinitely. In order to ensure that the end method is always invoked, these methods should be used within a try ... finally block:
try { begin(); // Perform blocking I/O operation here ... } finally { end(); }
This class also defines methods for maintaining a selector's cancelled-key set and for removing a key from its channel's key set, and declares the abstract register method that is invoked by a selectable channel's register method in order to perform the actual work of registering a channel.

(close this)Closes this selector.
If the selector has already been closed then this method returns immediately. Otherwise it marks the selector as closed and then invokes the implCloseSelector method in order to complete the close operation.
throws: java.io.IOException - If an I/O error occurs

open?clj
(open? this)Description copied from class: Selector
returns: true if, and only if, this selector is open - boolean
Description copied from class: Selector returns: true if, and only if, this selector is open - `boolean`
providerclj
(provider this)Returns the provider that created this channel.
returns: The provider that created this channel - java.nio.channels.spi.SelectorProvider
Returns the provider that created this channel. returns: The provider that created this channel - `java.nio.channels.spi.SelectorProvider`
