Method Details
+ + +
+

__init__(self, + minconn, + maxconn, + *args, + **kwargs) +
(Constructor) +

+

Initialize the connection pool.

+

New 'minconn' connections are created immediately calling 'connfunc' +with given parameters. The connection pool will support a maximum of +about 'maxconn' connections.

+
+
Overrides:
+
__builtin__.object.__init__
+
+
+
+ + +
+

_closeall(self) +

+

Close all connections.

+

Note that this can lead to some code fail badly when trying to use +an already closed connection. If you call .closeall() make sure +your code can deal with it.

+
+
+
+ + +
+

_connect(self, + key=None) +

+

Create a new connection and assign it to 'key' if not None.

+
+
+
+ + +
+

_getconn(self, + key=None) +

+

Get a free connection and assign it to 'key' if not None.

+
+
+
+ + +
+

_getkey(self) +

+

Return a new unique key.

+
+
+
+ + +
+

_putconn(self, + conn, + key=None, + close=False) +

+

Put away a connection.
