Class Configuration

  Configuration

All Implemented Interfaces:

Serializable

public final class Configuration
extends Object
implements Serializable

This class applies settings from a configuration file that lists variable names and values (see "example-settings.txt" in this directory for an example). Multiple configuration files can be read, and the results can be re-written to a new configuration file.

Important note: classes that have fields set via this Configuration (dkconfig) interface may not reference daikon.Global in their static initializers, since Global loads the default configuration, which classloads that class, and we have a classloading circularity.

Method Detail

getInstance

public static Configuration getInstance()

Returns:

singleton instance of this class

replay

public void replay()

overlap

public void overlap(Configuration config)

Take the settings given in the argument and call this.apply(String) for each of them. This essentially overlaps the settings given in the argument over this (appending them to this in the process). This method is intended for loading a saved configuration from a file, since calling this method with the Configuration singleton makes no sense.
