public class RefreshableAddressProvider extends Base implements DescribableAddressProvider
Modifier and Type | Class | Description |
---|---|---|
protected class |
RefreshableAddressProvider.CircularIterator |
An Iterator implementation that can be converted into
circular mode to allow the remaining addresses and previously skipped
addresses to be used; typically set once an address has been accepted . |
protected class |
RefreshableAddressProvider.RefreshThread |
Base.LoggingWriter, Base.StackFrame
Modifier and Type | Field | Description |
---|---|---|
protected Daemon |
f_daemonRefresh |
The refresh daemon.
|
protected RefreshableAddressProvider.CircularIterator |
f_iterator |
An Iterator over the cached set of addresses.
|
protected long |
f_lRefresh |
The interval with which to attempt to refresh the address list.
|
protected AddressProvider |
m_apRefresh |
The address provider to be refreshed.
|
protected long |
m_ldtLastRefresh |
The last timestamp when the address list was refreshed.
|
protected List |
m_listCache |
The cached addresses.
|
static long |
REFRESH_DEFAULT |
Default refresh time of 10 seconds.
|
Constructor | Description |
---|---|
RefreshableAddressProvider(AddressProvider ap) |
Construct a RefreshableAddressProvider with the given AddressProvider
using default refresh interval
|
RefreshableAddressProvider(AddressProvider ap,
long lRefresh) |
Construct a RefreshableAddressProvider with the specified AddressProvider
and refresh interval
|
Modifier and Type | Method | Description |
---|---|---|
void |
accept() |
This method should be called by the client immediately after it determines
that it can successfully use an address returned by the
SocketAddressProvider.getNextAddress() method. |
protected void |
ensureRefreshThread() |
Start the refresh thread if not already running.
|
boolean |
equals(Object o) |
SocketAddressProvider instances are considered equivalent iff they
consistently produce the same resulting set of addresses.
|
String[] |
getAddressDescriptions() |
Retrieve a human readable description of underlying addresses.
|
InetSocketAddress |
getNextAddress() |
Covariant of
SocketAddressProvider.getNextAddress() which
returns an InetSocketAddress . |
protected InetSocketAddress |
getNextAddressInternal() |
Obtain the next available address to use.
|
int |
hashCode() |
Return the hash code for this SocketAddressProvider.
|
protected void |
refreshAddressList() |
Refresh the cached address list using the underlying provider.
|
void |
reject(Throwable eCause) |
This method should be called by the client immediately after it determines
that an attempt to use an address returned by the
SocketAddressProvider.getNextAddress()
method has failed. |
