Creates a selectable channel to a file descriptor that supports an
operation-set
of
OP_READ
and
OP_WRITE
. The selectable channel will be created by the default
SelectorProvider
.
The given file descriptor is a socket or resource that can be multiplexed by a Selector
for read and write readiness. Great care is required to coordinate direct use of the file descriptor with the use of the selectable channel. In particular, changing the blocking mode or closing the file descriptor without careful coordination will result in unspecified and unsafe side effects. The given SelectableChannelCloser
is invoked to close the file descriptor and to coordinate the closing when the channel is registered with a Selector
.
If there is a security manager set then its checkRead
and checkWrite
methods are invoked to check that the caller has permission to both read from and write to the file descriptor.
