Method Detail

values

public static AbstractClientChannel.NullIoInputStream[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (AbstractClientChannel.NullIoInputStream c : AbstractClientChannel.NullIoInputStream.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static AbstractClientChannel.NullIoInputStream valueOf(java.lang.String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.NullPointerException - if the argument is null

close

public CloseFuture close(boolean immediately)

Description copied from interface: Closeable

Close this resource asynchronously and return a future. Resources support two closing modes: a graceful mode which will cleanly close the resource and an immediate mode which will close the resources abruptly.

Specified by:

close in interface Closeable

Parameters:

immediately - true if the resource should be shut down abruptly, false for a graceful close

Returns:

a CloseFuture representing the close request

addCloseFutureListener

public void addCloseFutureListener(SshFutureListener<CloseFuture> listener)

Description copied from interface: Closeable

Pre-register a listener to be informed when resource is closed. If resource is already closed, the listener will be invoked immediately and not registered for future notification

Specified by:

addCloseFutureListener in interface Closeable

Parameters:

listener - The notification SshFutureListener - never null

removeCloseFutureListener

public void removeCloseFutureListener(SshFutureListener<CloseFuture> listener)

Description copied from interface: Closeable

Remove a pre-registered close event listener

Specified by:

removeCloseFutureListener in interface Closeable

Parameters:

listener - The register SshFutureListener - never null. Ignored if not registered or resource already closed

isClosed

public boolean isClosed()

Description copied from interface: Closeable

Returns true if this object has been closed.

Specified by:

isClosed in interface Closeable

Returns:

true if closing

isClosing

public boolean isClosing()

Description copied from interface: Closeable

Returns true if the Closeable.close(boolean) method has been called. Note that this method will return true even if this Closeable.isClosed() returns true.

Specified by:

isClosing in interface Closeable

Returns:

true if closing

read

public IoReadFuture read(Buffer buffer)

Description copied from interface: IoInputStream

NOTE: the buffer must not be touched until the returned read future is completed.

Specified by:

read in interface IoInputStream

Parameters:

buffer - the Buffer to use

Returns:

The IoReadFuture for the operation
