Java Source Code / Java Documentation » Web Server » Jigsaw » org.w3c.util   Source Cross Reference   Class Diagram   Java Document (Java Doc)   java.util.Properties    org.w3c.util.ObservableProperties ObservableProperties public class ObservableProperties extends Properties (Code) An enhanced property class that provides support to monitor changes. This class extends the basic properties class of Java, by providing monitoring support. It also provides more type conversion. See Also:   PropertyMonitoring Field Summary  PropertyMonitoring observers       int observers_count      Constructor Summary public   ObservableProperties(Properties props)      Build an httpdProperties instance from a Properties instance. Method Summary public  boolean getBoolean(String name, boolean def)      Get this property value, as a boolean. Parameters:   name - The name of the property to be fetched. Parameters:   def - The default value, if the property isn't defined. public  double getDouble(String name, double def)      Get this property value, as a double. Parameters:   name - The name of the property. Parameters:   def - The default value if undefined. public  File getFile(String name, File def)      Get this property value, as a File. Parameters:   name - The name of the property to be fetched.

Parameters:   name - The name of the property to be fetched. Parameters:   def - The default value, if the property isn't defined. public  String[] getStringArray(String name, String def)      Get this property as a String array. By convention, properties that are get as string arrays should be encoded as a | separated list of Strings. Parameters:   name - The property's name. Parameters:   def - The default value (if undefined). public synchronized  boolean putValue(String name, String value)      Update a property value. Assign a value to a property. public synchronized  void registerObserver(PropertyMonitoring o)      Subscribe for property monitoring. public synchronized  boolean unregisterObserver(PropertyMonitoring o)      Unsubscribe this object from the observers list. Parameters:   observer - The observer to unsubscribe. Field Detail observers PropertyMonitoring observers(Code) observers_count int observers_count(Code) Constructor Detail ObservableProperties public ObservableProperties(Properties props)(Code) Build an httpdProperties instance from a Properties instance. Parameters:   props - The Properties instance. Method Detail getBoolean public boolean getBoolean(String name, boolean def)(Code) Get this property value, as a boolean. Parameters:   name - The name of the property to be fetched. Parameters:   def - The default value, if the property isn't defined. A Boolean instance. getDouble public double getDouble(String name, double def)(Code) Get this property value, as a double. Parameters:   name - The name of the property. Parameters:   def - The default value if undefined. A double value. getFile public File getFile(String name, File def)(Code) Get this property value, as a File. Parameters:   name - The name of the property to be fetched. Parameters:   def - The default value, if the property isn't defined. An instance of File. getInteger public int getInteger(String name, int def)(Code) Get this property value, as an integer. Parameters:   name - The name of the property to be fetched. Parameters:   def - The default value, if the property isn't defined. An integer value. getLong public long getLong(String name, long def)(Code) getString public String getString(String name, String def)(Code) Get this property value, as a String. Parameters:   name - The name of the property to be fetched. Parameters:   def - The default value, if the property isn't defined. An instance of String. getStringArray public String[] getStringArray(String name, String def)(Code) Get this property as a String array. By convention, properties that are get as string arrays should be encoded as a | separated list of Strings. Parameters:   name - The property's name. Parameters:   def - The default value (if undefined). A String array, or null if the propertyis undefined. putValue public synchronized boolean putValue(String name, String value)(Code) Update a property value. Assign a value to a property. If the property value has really changed notify our observers of the change. Parameters:   name - The name of the property to assign. Parameters:   value - The new value for this property, or nullif the property setting is to be cancelled. A boolean true if change was accepted by our observers, false otherwise. registerObserver public synchronized void registerObserver(PropertyMonitoring o)(Code) Subscribe for property monitoring. Parameters:   observer - The object that handles the PropertyMonitoring interface. unregisterObserver public synchronized boolean unregisterObserver(PropertyMonitoring o)(Code) Unsubscribe this object from the observers list. Parameters:   observer - The observer to unsubscribe. A boolean true if object was succesfully unsubscribed, false otherwise.
