jdk.nio.channels.spi.AbstractSelectableChannel
Base implementation class for selectable channels.
This class defines methods that handle the mechanics of channel registration, deregistration, and closing. It maintains the current blocking mode of this channel as well as its current set of selection keys. It performs all of the synchronization required to implement the SelectableChannel specification. Implementations of the abstract protected methods defined in this class need not synchronize against other threads that might be engaged in the same operations.

blocking-lockclj
(blocking-lock this)Description copied from class: SelectableChannel
returns: The blocking-mode lock object - java.lang.Object
Description copied from class: SelectableChannel returns: The blocking-mode lock object - `java.lang.Object`
blocking?clj
(blocking? this)Description copied from class: SelectableChannel
returns: true if, and only if, this channel is in blocking mode - boolean
Description copied from class: SelectableChannel returns: true if, and only if, this channel is in blocking mode - `boolean`
configure-blockingclj
(configure-blocking this block)Adjusts this channel's blocking mode.
If the given blocking mode is different from the current blocking mode then this method invokes the implConfigureBlocking method, while holding the appropriate locks, in order to change the mode.
block - If true then this channel will be placed in blocking mode; if false then it will be placed non-blocking mode - boolean
returns: This selectable channel - java.nio.channels.SelectableChannel
throws: java.nio.channels.ClosedChannelException - If this channel is closed
Adjusts this channel's blocking mode. If the given blocking mode is different from the current blocking mode then this method invokes the implConfigureBlocking method, while holding the appropriate locks, in order to change the mode. block - If true then this channel will be placed in blocking mode; if false then it will be placed non-blocking mode - `boolean` returns: This selectable channel - `java.nio.channels.SelectableChannel` throws: java.nio.channels.ClosedChannelException - If this channel is closed
key-forclj
(key-for this sel)Description copied from class: SelectableChannel
sel - The selector - java.nio.channels.Selector
returns: The key returned when this channel was last registered with the
given selector, or null if this channel is not
currently registered with that selector - java.nio.channels.SelectionKey
Description copied from class: SelectableChannel
sel - The selector - `java.nio.channels.Selector`
returns: The key returned when this channel was last registered with the
given selector, or null if this channel is not
currently registered with that selector - `java.nio.channels.SelectionKey`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`
registerclj
(register this sel ops att)Registers this channel with the given selector, returning a selection key.
This method first verifies that this channel is open and that the given initial interest set is valid.
If this channel is already registered with the given selector then the selection key representing that registration is returned after setting its interest set to the given value.
Otherwise this channel has not yet been registered with the given selector, so the register method of the selector is invoked while holding the appropriate locks. The resulting key is added to this channel's key set before being returned.
sel - The selector with which this channel is to be registered - java.nio.channels.Selector
ops - The interest set for the resulting key - int
att - The attachment for the resulting key; may be null - java.lang.Object
returns: A key representing the registration of this channel with
the given selector - java.nio.channels.SelectionKey
throws: java.nio.channels.ClosedSelectorException - If the selector is closed
Registers this channel with the given selector, returning a selection key.
This method first verifies that this channel is open and that the
given initial interest set is valid.
If this channel is already registered with the given selector then
the selection key representing that registration is returned after
setting its interest set to the given value.
Otherwise this channel has not yet been registered with the given
selector, so the register method of
the selector is invoked while holding the appropriate locks. The
resulting key is added to this channel's key set before being returned.
sel - The selector with which this channel is to be registered - `java.nio.channels.Selector`
ops - The interest set for the resulting key - `int`
att - The attachment for the resulting key; may be null - `java.lang.Object`
returns: A key representing the registration of this channel with
the given selector - `java.nio.channels.SelectionKey`
throws: java.nio.channels.ClosedSelectorException - If the selector is closedregistered?clj
(registered? this)Description copied from class: SelectableChannel
returns: true if, and only if, this channel is registered - boolean
Description copied from class: SelectableChannel returns: true if, and only if, this channel is registered - `boolean`
