构造器详细资料

LoadBalanceConnectionUrl

public LoadBalanceConnectionUrl(ConnectionUrlParser connStrParser,
                                Properties info)

Constructs an instance of LoadBalanceConnectionUrl, performing all the required initializations and validations. A load-balanced connection cannot deal with multiple hosts with same host:port.

参数:

connStrParser - a ConnectionUrlParser instance containing the parsed version of the original connection string

info - the connection arguments map

LoadBalanceConnectionUrl

public LoadBalanceConnectionUrl(List<HostInfo> hosts,
                                Map<String,String> properties)

Constructs an instance of a LoadBalanceConnectionUrl based on a list of hosts and a global set of properties instead of connection string parsing. ConnectionUrl instances created by this process are not cached.

参数:

hosts - the hosts list to use in this connection URL

properties - the properties common to all hosts

方法详细资料

injectPerTypeProperties

protected void injectPerTypeProperties(Map<String,String> props)

Injects additional properties into the connection arguments while it's being constructed.

覆盖:

injectPerTypeProperties 在类中 ConnectionUrl

参数:

props - the properties already containing all known connection arguments

getHostInfoListAsHostPortPairs

public List<String> getHostInfoListAsHostPortPairs()

Returns a list of this connection URL hosts in the form of host:port pairs.

返回:

a list of this connection URL hosts in the form of host:port pairs

getHostInfoListFromHostPortPairs

public List<HostInfo> getHostInfoListFromHostPortPairs(Collection<String> hostPortPairs)

Returns the list of HostInfo instances that matches the given collection of host:port pairs. Isolated host info elements are spawned for the missing elements.

参数:

hostPortPairs - a list of host:port pairs

返回:

a list of HostInfo instances corresponding to the given host:port pairs
