Class DefaultConfiguration

java.lang.Object
  |
  +--com.solarmetric.kodo.conf.DefaultConfiguration

All Implemented Interfaces:: Cloneable, Configuration, Serializable

Direct Known Subclasses:: SimpleConfiguration

public abstract class DefaultConfiguration
extends Object
implements Configuration, Cloneable

This Configuration type initializes from the settings in either the kodo.properties properties file. Any recognized property can also be overridden by setting the System property of the same name to the desired value.

If the kodo.properties file is not present the system will search for the system.prefs XML file and load from it, though the use of this file should be considered deprecated.

Either file must be located at the top level of the CLASSPATH for the context loader of the creating thread. Alternatively, the location of the properties file can be specified by setting the com.solarmetric.kodo.properties system property; the location of the XML resource can similarly be specified by setting the solarmetric.system.prefs system property.

Note that changing any properties of this Configuration will not result in changes to the files, and therefore will not be visible to other instances or after the JVM has restarted.

See the Configuration interface for lists of recognized properties, XML preferences.

Method Summary

protected void checkFrozen()
          Checks if the configuration has been frozen and if so throws a JDOUserException, otherwise returns silently.

Object clone()
          Returns a clone of this Configuration.

Configuration configurationClone()
          Return a new Configuration that is an exact copy of this one.

boolean equals(Object other)
          Performs the equality check based on set property values from toProperties().

void freeze()
          Freeze this Configuration; if frozen, calls to checkFrozen() will throw a JDOUserException.

void fromProperties(Properties properties)
          Set this Configuration via the given Properties.

int hashCode()
          Computes hash code based on set property values from toProperties().

boolean isFrozen()
          Return true if this Configuration has been frozen.

protected void loadDefaults()
          Invoke this method to load default values from properties/prefs.

protected void setFromPreferences()
          Override this method to support setting subclass state from preferences.

protected void setFromProperties(TypedProperties props)
          Override this method to support setting subclass state from properties.

protected void setToProperties(TypedProperties props)
          Override this method to support serializing subclass state to properties.

Properties toProperties()
          A Properties representation of this Configuration.

Method Detail

loadDefaults

protected void loadDefaults()

Invoke this method to load default values from properties/prefs. This is not performed on construction so that subclasses can initialize state before loading defaults.
