public class SpyConfig
extends Properties

SpyConfig - an abstracted config file maintainer. The current config file format is that of a java Properties file. This class makes it easier to load them, caches them, and gives a good base for extensions that load default config files for projects that are hard to pass config filepaths into.

Constructor Detail

SpyConfig

public SpyConfig(File conffile)

Construct a new SpyConfig object describing a config file.

Parameters:

conffile - The config file we are describing.

SpyConfig

public SpyConfig()

Construct a new SpyConfig object without a config file.

Method Detail

loadConfig

public boolean loadConfig(File conffile)

Try to load a config file. This function exists primarily for classes that extend SpyConfig and want to have multiple default locations for config files.

Parameters:

conffile - Path to the configuration file to load.

Returns:

true if the config loaded successfully.

loadConfig

public boolean loadConfig(File[] confFiles)

Try to load a config file. This function allows an object to load a config file from a list of files. Only the first file in the list that works is actually loaded.

Parameters:

confFiles - an array of config file paths to attempt to load

Returns:

true if a config file was loaded

get

public String get(String key)

Get the value for a given config entry.

Parameters:

key - which config entry to return.

get

public String get(String key,
                  String def)

Get the value for a given config entry, with default.

Parameters:

key - which config entry to return.

def - default in case the entry doesn't exist.

getInt

public int getInt(String key,
                  int def)

Get an int value for a given config entry. Please note, a default is *required* because undefined ints suck.

Parameters:

key - which config entry to return.

def - default in case the entry doesn't exist.

orput

public void orput(String key,
                  String value)

Assign a value to the config only if it doesn't already exist. Useful for setting defaults.

Parameters:

key - config key

value - config value
