Class PropManager

java.lang.Object

com.highqsoft.util.PropManager

All Implemented Interfaces:

java.io.Serializable

public class PropManager
extends java.lang.Object
implements java.io.Serializable

This class keeps track of the default properties.

We manage three levels of defaults: user defaults, system defaults and basic defaults. A call to PropManager.get() checks all three levels in order and returns the first non-null value for a key, if any.

A call to PropManager.put() just affects the user defaults. If the initialize routine will be used with the arguments of the main routine, it is possible to overload each property value. The syntax for that behaviour is

    -key value
 

for a key value pair or

    -key
 

for a boolean value.

The initialization looks first for command line argument and collect the given key value pairs. Then it reads the property file /lib/highqsoft.properties. This value can be overwritten by the command line keyword -highqsoft.properties. Then it looks for the keywords basic.properties, system.properties and user.properties in order. These values can be set inside the highqsoft.properties file or even by command line arguments that overwrite the highqsoft.properties. The file basic.properties will overload the values inside the BasicProperties class that builds the basic property table. The others will build the system and the user property table.

Warning: The basic property table is the last instance to found a meaningful value. This can lead to an exception because all classes that use the PropManager expect a useful value. e.g: If the user makes an incorrect font specification for the basic property table, the PropManager returns null for that property.

Warning: serialized objects of this class will not be compatible with future swing releases. The current serialization support is appropriate for short term storage or RMI between Swing1.0 applications. It will not be possible to load serialized Swing1.0 objects with future releases of Swing. The JDK1.2 release of Swing will be the compatibility baseline for the serialized form of Swing objects.
