Class LogFactory

java.lang.Object
  org.apache.commons.logging.LogFactory

Direct Known Subclasses:: SLF4JLogFactory

public abstract class LogFactory
extends Object
extends Object

Factory for creating Log instances, which always delegates to an instance of SLF4JLogFactory. Binds statically to MuleLogFactory

Field Summary
`static String`	`DIAGNOSTICS_DEST_PROPERTY` The name (`org.apache.commons.logging.diagnostics.dest`) of the property used to enable internal commons-logging diagnostic output, in order to get information on what logging implementations are being discovered, what classloaders they are loaded through, etc.
`protected static Hashtable`	`factories` The previously constructed `LogFactory` instances, keyed by the `ClassLoader` with which it was created.
`static String`	`FACTORY_DEFAULT` The fully qualified class name of the fallback `LogFactory` implementation class to use, if no other can be found.
`static String`	`FACTORY_PROPERTIES` The name of the properties file to search for.
`static String`	`FACTORY_PROPERTY` The name of the property used to identify the LogFactory implementation class name.
`static String`	`HASHTABLE_IMPLEMENTATION_PROPERTY` Setting this system property value allows the `Hashtable` used to store classloaders to be substituted by an alternative implementation.
`protected static LogFactory`	`nullClassLoaderFactory` This property is not used but preserved here for compatibility.
`static String`	`PRIORITY_KEY` The name (`priority`) of the key in the config file used to specify the priority of that particular config file.
`protected static String`	`SERVICE_ID` JDK1.3+ 'Service Provider' specification.
`static String`	`TCCL_KEY` The name (`use_tccl`) of the key in the config file used to specify whether logging classes should be loaded via the thread context class loader (TCCL), or not.

Constructor Summary
`protected`	`LogFactory()` Protected constructor that is not available for public use.

Method Summary
`protected static Object`	`createFactory(String factoryClass, ClassLoader classLoader)` This method exists to ensure signature compatibility.
`protected static ClassLoader`	`directGetContextClassLoader()` This method exists to ensure signature compatibility.
`abstract Object`	`getAttribute(String name)` Return the configuration attribute with the specified name (if any), or `null` if there is no such attribute.
`abstract String[]`	`getAttributeNames()` Return an array containing the names of all currently defined configuration attributes.
`protected static ClassLoader`	`getClassLoader(Class clazz)` This method exists to ensure signature compatibility.
`protected static ClassLoader`	`getContextClassLoader()` This method exists to ensure signature compatibility.
`static LogFactory`	`getFactory()` Construct (if necessary) and return a `LogFactory` instance, using the following ordered lookup procedure to determine the name of the implementation class to be loaded.
`abstract Log`	`getInstance(Class clazz)` Convenience method to derive a name from the specified class and call `getInstance(String)` with it.
`abstract Log`	`getInstance(String name)` Construct (if necessary) and return a `Log` instance, using the factory's current set of configuration attributes.
`static Log`	`getLog(Class clazz)` Convenience method to return a named logger, without the application having to care about factories.
`static Log`	`getLog(String name)` Convenience method to return a named logger, without the application having to care about factories.
`protected static boolean`	`isDiagnosticsEnabled()` This method exists to ensure signature compatibility.
`protected static void`	`logRawDiagnostic(String msg)` This method exists to ensure signature compatibility.
`protected static LogFactory`	`newFactory(String factoryClass, ClassLoader classLoader)` This method exists to ensure signature compatibility.
`protected static LogFactory`	`newFactory(String factoryClass, ClassLoader classLoader, ClassLoader contextClassLoader)` This method exists to ensure signature compatibility.
`static String`	`objectId(Object o)` Returns a string that uniquely identifies the specified object, including its class.
`abstract void`	`release()` Release any internal references to previously created `Log`instances returned by this factory.
`static void`	`release(ClassLoader classLoader)` Release any internal references to previously created `LogFactory` instances that have been associated with the specified class loader (if any), after calling the instance method `release()` on each of them.
`static void`	`releaseAll()` Release any internal references to previously created `LogFactory` instances, after calling the instance method `release()` on each of them.
`abstract void`	`removeAttribute(String name)` Remove any configuration attribute associated with the specified name.
`abstract void`	`setAttribute(String name, Object value)` Set the configuration attribute with the specified name.

Field Detail

PRIORITY_KEY

public static final String PRIORITY_KEY

The name (priority) of the key in the config file used to specify the priority of that particular config file. The associated value is a floating-point number; higher values take priority over lower values.
