| Method Summary | |
| native public static int | add(long pollset, long sock, int reqevents)
Add a socket or to a pollset
If you set client_data in the descriptor, that value
will be returned in the client_data field whenever this
descriptor is signalled in apr_pollset_poll(). | | native public static long | create(int size, long p, int flags, long ttl)
Setup a pollset object.
If flags equals APR_POLLSET_THREADSAFE, then a pollset is
created on which it is safe to make concurrent calls to
apr_pollset_add(), apr_pollset_remove() and apr_pollset_poll() from
separate threads. | | native public static int | destroy(long pollset)
| | native public static long | getTtl(long pollset)
Get the socket time to live. | | native public static int | maintain(long pollset, long[] descriptors, boolean remove)
| | native public static int | poll(long pollset, long timeout, long[] descriptors, boolean remove)
| | native public static int | pollset(long pollset, long[] descriptors)
| | native public static int | remove(long pollset, long sock)
| | native public static void | setTtl(long pollset, long ttl)
Set the socket time to live. |
| APR_NO_DESC | | final public static int APR_NO_DESC(Code) | | Used in apr_pollfd_t to determine what the apr_descriptor is
apr_datatype_e enum
|
| APR_POLLERR | | final public static int APR_POLLERR(Code) | | Can write without blocking
|
| APR_POLLHUP | | final public static int APR_POLLHUP(Code) | | Pending error
|
| APR_POLLIN | | final public static int APR_POLLIN(Code) | | Poll options
|
| APR_POLLNVAL | | final public static int APR_POLLNVAL(Code) | | Hangup occurred
|
| APR_POLLOUT | | final public static int APR_POLLOUT(Code) | | Priority data available
|
| APR_POLLPRI | | final public static int APR_POLLPRI(Code) | | Can read without blocking
|
| APR_POLLSET_THREADSAFE | | final public static int APR_POLLSET_THREADSAFE(Code) | | Adding or Removing a Descriptor is thread safe
|
| APR_POLL_FILE | | final public static int APR_POLL_FILE(Code) | | descriptor refers to a socket
|
| APR_POLL_LASTDESC | | final public static int APR_POLL_LASTDESC(Code) | | descriptor refers to a file
|
| APR_POLL_SOCKET | | final public static int APR_POLL_SOCKET(Code) | | nothing here
|
| add | | native public static int add(long pollset, long sock, int reqevents)(Code) | | Add a socket or to a pollset
If you set client_data in the descriptor, that value
will be returned in the client_data field whenever this
descriptor is signalled in apr_pollset_poll().
Parameters:
pollset - The pollset to which to add the descriptor
Parameters:
sock - The sockets to add
Parameters:
data - Client data to add
Parameters:
reqevents - requested events |
| create | | native public static long create(int size, long p, int flags, long ttl) throws Error(Code) | | Setup a pollset object.
If flags equals APR_POLLSET_THREADSAFE, then a pollset is
created on which it is safe to make concurrent calls to
apr_pollset_add(), apr_pollset_remove() and apr_pollset_poll() from
separate threads. This feature is only supported on some
platforms; the apr_pollset_create() call will fail with
APR_ENOTIMPL on platforms where it is not supported.
Parameters:
size - The maximum number of descriptors that this pollset can hold
Parameters:
p - The pool from which to allocate the pollset
Parameters:
flags - Optional flags to modify the operation of the pollset.
Parameters:
ttl - Maximum time to live for a particular socket. The pointer in which to return the newly created object |
| destroy | | native public static int destroy(long pollset)(Code) | | Destroy a pollset object
Parameters:
pollset - The pollset to destroy |
| getTtl | | native public static long getTtl(long pollset)(Code) | | Get the socket time to live.
Parameters:
pollset - The pollset to use Timeout in microseconds |
| maintain | | native public static int maintain(long pollset, long[] descriptors, boolean remove)(Code) | | Maintain on the descriptor(s) in a pollset
Parameters:
pollset - The pollset to use
Parameters:
descriptors - Array of signalled descriptors (output parameter)The desctiptor array must be the size of pollset.and are populated as follows:descriptors[n] -> socket
Parameters:
remove - Remove signaled descriptors from pollset Number of signalled descriptors (output parameter)or negative APR error code. |
| poll | | native public static int poll(long pollset, long timeout, long[] descriptors, boolean remove)(Code) | | Block for activity on the descriptor(s) in a pollset
Parameters:
pollset - The pollset to use
Parameters:
timeout - Timeout in microseconds
Parameters:
descriptors - Array of signalled descriptors (output parameter)The desctiptor array must be two times the size of pollset.and are populated as follows:descriptors[n + 0] -> returned eventsdescriptors[n + 1] -> socket
Parameters:
remove - Remove signaled descriptors from pollset Number of signalled descriptors (output parameter)or negative APR error code. |
| pollset | | native public static int pollset(long pollset, long[] descriptors)(Code) | | Return all descriptor(s) in a pollset
Parameters:
pollset - The pollset to use
Parameters:
descriptors - Array of descriptors (output parameter)The desctiptor array must be two times the size of pollset.and are populated as follows:descriptors[n + 0] -> returned eventsdescriptors[n + 1] -> socket Number of descriptors (output parameter) in the Pollor negative APR error code. |
| remove | | native public static int remove(long pollset, long sock)(Code) | | Remove a descriptor from a pollset
Parameters:
pollset - The pollset from which to remove the descriptor
Parameters:
sock - The socket to remove |
| setTtl | | native public static void setTtl(long pollset, long ttl)(Code) | | Set the socket time to live.
Parameters:
pollset - The pollset to use
Parameters:
ttl - Timeout in microseconds |
