use ResourcePool::Resource;

my $resource = ResourcePool::Resource->new();

This class is a base class for the resources which will be used with ResourcePool. ResourcePool uses this class internally to have a unique interface to interact with the resource.

Each ResourcePool::Resource class gets constructed by the corresponding ResourcePool::Factory class. In fact the Factory classes are just used to store the parameters which are required to construct a resource.

Every class which is derived from ResourcePool::Resource must override the close, fail_close and get_plain_resource methods and should override at least one of precheck or postcheck.

Closes a connection gracefully.

Closes a failed connection and ignores error (since this connection is known to be broken)

Returns the naked resource which can be used by the client. This is the DBI or Net::LDAP handle for example.

Checks a connection. This method is called by the get() method of the ResourcePool before it returns a connection. The default implementation always returns true.

Checks a connection. This method is called by the free() method of the ResourcePool to check if a connection is still valid. The default implementation always returns true.
