Constructor Detail

Prototyper

public Prototyper(org.logicalcobwebs.proxool.ConnectionPool connectionPool)

Method Detail

getConnectionCount

public long getConnectionCount()

The total number of connections, including those being built right now

Returns:

connectionCount;

cancel

public void cancel()

Cancel all current prototyping

getAlias

public java.lang.String getAlias()

The alias of the pool we are prototyping for

Returns:

alias

quickRefuse

public void quickRefuse()
                 throws java.sql.SQLException

Give a quick answer to whether we should attempt to build a connection. This can be quicker if we are massively overloaded rather than cycling through each connection in the pool to see if it's free

Throws:

java.sql.SQLException - if it is a waste of time even trying to get a connaction. Just because this method doesn't throw an exception it doesn't guarantee that one will be available. There is a slight risk that we might tell the client to give up when a connection could become available in the next few milliseconds but our policy is to refuse connections quickly when overloaded.
