Method Details

getImplementationName

public String getImplementationName()

Description copied from interface: NamedImplementation

Get a name for the implementing class. Useful for abstract classes that implement LogOutputAppendable or override toString.

The default implementation is correct, but not suitable for high-frequency usage.

Returns:

A name for the implementing class

refresh

public void refresh()

Description copied from interface: TableLocation

Initialize or run state information.
