方法详细资料

genRandomKeyToSelectCon

public int genRandomKeyToSelectCon()

getConnection

public CompletableFuture<ClientCnx> getConnection(InetSocketAddress address)

getConnection

public CompletableFuture<ClientCnx> getConnection(InetSocketAddress logicalAddress,
 InetSocketAddress physicalAddress,
 int randomKey)

Get a connection from the pool.

The connection can either be created or be coming from the pool itself.

When specifying multiple addresses, the logicalAddress is used as a tag for the broker, while the physicalAddress is where the connection is actually happening.

These two addresses can be different when the client is forced to connect through a proxy layer. Essentially, the pool is using the logical address as a way to decide whether to reuse a particular connection.

参数:

logicalAddress - the address to use as the broker tag

physicalAddress - the real address where the TCP connection should be made

返回:

a future that will produce the ClientCnx object

releaseConnection

public void releaseConnection(ClientCnx cnx)

close

public void close()
           throws Exception

指定者:

close 在接口中 AutoCloseable

抛出:

Exception

doMarkAndReleaseUselessConnections

public void doMarkAndReleaseUselessConnections()

getConnections

public Set<CompletableFuture<ClientCnx>> getConnections()
