Class Configuration

Object

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 would have a classloading circularity.

Method Detail

getInstance

public static Configuration getInstance()

Returns the singleton instance of this class.

Returns:

the 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.

apply

public void apply(InputStream input)

Apply the settings in the given InputStream.

Parameters:

input - the commands to set confiuration

apply

public void apply(String line)

Apply the setting in the given InputStream.

Parameters:

line - the command to set confiuration

apply

public void apply(String name,
                  String value)

Set the given setting to the given value.

Parameters:

name - the setting to modify

value - the setting's new value

public void apply(@ClassGetName String classname,
                  String fieldname,
                  String value)
