PropertyManager

public class PropertyManager (Code)

Manages properties for the entire Yazd system. Properties are merely pieces of information that need to be saved in between server restarts. The class also reports the version of Yazd.

At the moment, properties are stored in a Java Properties file. In a version of Yazd coming soon, the properties file format will move to XML. XML properties will allow hierarchical property structures which may mean the API of this class will have to change.

Yazd properties are only meant to be set and retrevied by core Yazd classes. Therefore, skin writers should probably ignore this class.

This class is implemented as a singleton since many classloaders seem to take issue with doing classpath resource loading from a static context.

public static void	deleteProperty(String name) Deletes a Yazd property.
protected String	getProp(String name) Gets a Yazd property.
public static String	getProperty(String name) Returns a Yazd property. Parameters: name - the name of the property to return.
public static String	getYazdVersion() Returns the version number of Yazd as a String.
public static int	getYazdVersionMajor() Returns the major version number of Yazd.
public static int	getYazdVersionMinor() Returns the minor version number of Yazd.
public static int	getYazdVersionRevision() Returns the revision version number of Yazd.
public boolean	propFileExists() Returns true if the yazd.properties file exists where the path property purports that it does.
public boolean	propFileIsReadable() Returns true if the properties are readable.
public boolean	propFileIsWritable() Returns true if the properties are writable.
protected Enumeration	propNames()
public static boolean	propertyFileExists() Returns true if the yazd.properties file exists where the path property purports that it does.
public static boolean	propertyFileIsReadable() Returns true if the properties are readable.
public static boolean	propertyFileIsWritable() Returns true if the properties are writable.
public static Enumeration	propertyNames() Returns the names of the Yazd properties.
public static void	setPath(String path)
protected void	setProp(String name, String value) Sets a Yazd property.
public static void	setProperty(String name, String value) Sets a Yazd property.

Method Detail

deleteProp
protected void deleteProp(String name)(Code)

deleteProperty
public static void deleteProperty(String name)(Code)
	Deletes a Yazd property. If the property doesn't exist, the method does nothing. Parameters: name - the name of the property to delete.

getProp
protected String getProp(String name)(Code)
	Gets a Yazd property. Yazd properties are stored in yazd.properties. The properties file should be accesible from the classpath. Additionally, it should have a path field that gives the full path to where the file is located. Getting properties is a fast operation. Parameters: name - the name of the property to get. the property specified by name.

getProperty
public static String getProperty(String name)(Code)
	Returns a Yazd property. Parameters: name - the name of the property to return. the property value specified by name.

getYazdVersion
public static String getYazdVersion()(Code)
	Returns the version number of Yazd as a String. i.e. -- major.minor.revision

getYazdVersionMajor
public static int getYazdVersionMajor()(Code)
	Returns the major version number of Yazd. i.e. -- 1.x.x

getYazdVersionMinor
public static int getYazdVersionMinor()(Code)
	Returns the minor version number of Yazd. i.e. -- x.1.x

getYazdVersionRevision
public static int getYazdVersionRevision()(Code)
	Returns the revision version number of Yazd. i.e. -- x.x.1

propFileExists
public boolean propFileExists()(Code)
	Returns true if the yazd.properties file exists where the path property purports that it does.

propFileIsReadable
public boolean propFileIsReadable()(Code)
	Returns true if the properties are readable. This method is mainly valuable at setup time to ensure that the properties file is setup correctly.

propFileIsWritable
public boolean propFileIsWritable()(Code)
	Returns true if the properties are writable. This method is mainly valuable at setup time to ensure that the properties file is setup correctly.

propNames
protected Enumeration propNames()(Code)

propertyFileExists
public static boolean propertyFileExists()(Code)
	Returns true if the yazd.properties file exists where the path property purports that it does.

propertyFileIsReadable
public static boolean propertyFileIsReadable()(Code)
	Returns true if the properties are readable. This method is mainly valuable at setup time to ensure that the properties file is setup correctly.

propertyFileIsWritable
public static boolean propertyFileIsWritable()(Code)
	Returns true if the properties are writable. This method is mainly valuable at setup time to ensure that the properties file is setup correctly.

propertyNames
public static Enumeration propertyNames()(Code)
	Returns the names of the Yazd properties. an Enumeration of the Yazd property names.

setPath
public static void setPath(String path)(Code)

setProp
protected void setProp(String name, String value)(Code)
	Sets a Yazd property. Because the properties must be saved to disk every time a property is set, property setting is relatively slow.

setProperty
public static void setProperty(String name, String value)(Code)
	Sets a Yazd property. If the property doesn't already exists, a new one will be created. Parameters: name - the name of the property being set. Parameters: value - the value of the property being set.
