| 34 | +/** | |
| 35 | + * A Logger object is used to log messages for a specific | |
| 36 | + * system or application component. Loggers are normally named, | |
| 37 | + * using a hierarchical dot-separated namespace. Logger names | |
| 38 | + * can be arbitrary strings, but they should normally be based on | |
| 39 | + * the package name or class name of the logged component, such | |
| 40 | + * as java.net or javax.swing. In addition it is possible to create | |
| 41 | + * "anonymous" Loggers that are not stored in the Logger namespace. | |
| 42 | + * <p> | |
| 43 | + * Logger objects may be obtained by calls on one of the getLogger | |
| 44 | + * factory methods. These will either create a new Logger or | |
| 45 | + * return a suitable existing Logger. It is important to note that | |
| 46 | + * the Logger returned by one of the {@code getLogger} factory methods | |
| 47 | + * may be garbage collected at any time if a strong reference to the | |
| 48 | + * Logger is not kept. | |
| 49 | + * <p> | |
| 50 | + * Logging messages will be forwarded to registered Handler | |
| 51 | + * objects, which can forward the messages to a variety of | |
| 52 | + * destinations, including consoles, files, OS logs, etc. | |
| 53 | + * <p> | |
| 54 | + * Each Logger keeps track of a "parent" Logger, which is its | |
| 55 | + * nearest existing ancestor in the Logger namespace. | |
| 56 | + * <p> | |
| 57 | + * Each Logger has a "Level" associated with it. This reflects | |
| 58 | + * a minimum Level that this logger cares about. If a Logger's | |
| 59 | + * level is set to <tt>null</tt>, then its effective level is inherited | |
| 60 | + * from its parent, which may in turn obtain it recursively from its | |
| 61 | + * parent, and so on up the tree. | |
| 62 | + * <p> | |
| 63 | + * The log level can be configured based on the properties from the | |
| 64 | + * logging configuration file, as described in the description | |
| 65 | + * of the LogManager class. However it may also be dynamically changed | |
| 66 | + * by calls on the Logger.setLevel method. If a logger's level is | |
| 67 | + * changed the change may also affect child loggers, since any child | |
| 68 | + * logger that has <tt>null</tt> as its level will inherit its | |
| 69 | + * effective level from its parent. | |
| 70 | + * <p> | |
| 71 | + * On each logging call the Logger initially performs a cheap | |
| 72 | + * check of the request level (e.g., SEVERE or FINE) against the | |
| 73 | + * effective log level of the logger. If the request level is | |
| 74 | + * lower than the log level, the logging call returns immediately. | |
| 75 | + * <p> | |
| 76 | + * After passing this initial (cheap) test, the Logger will allocate | |
| 77 | + * a LogRecord to describe the logging message. It will then call a | |
| 78 | + * Filter (if present) to do a more detailed check on whether the | |
| 79 | + * record should be published. If that passes it will then publish | |
| 80 | + * the LogRecord to its output Handlers. By default, loggers also | |
| 81 | + * publish to their parent's Handlers, recursively up the tree. | |
| 82 | + * <p> | |
| 83 | + * Each Logger may have a ResourceBundle name associated with it. | |
| 84 | + * The named bundle will be used for localizing logging messages. | |
| 85 | + * If a Logger does not have its own ResourceBundle name, then | |
| 86 | + * it will inherit the ResourceBundle name from its parent, | |
| 87 | + * recursively up the tree. | |
| 88 | + * <p> | |
| 89 | + * Most of the logger output methods take a "msg" argument. This | |
| 90 | + * msg argument may be either a raw value or a localization key. | |
| 91 | + * During formatting, if the logger has (or inherits) a localization | |
| 92 | + * ResourceBundle and if the ResourceBundle has a mapping for the msg | |
| 93 | + * string, then the msg string is replaced by the localized value. | |
| 94 | + * Otherwise the original msg string is used. Typically, formatters use | |
| 95 | + * java.text.MessageFormat style formatting to format parameters, so | |
| 96 | + * for example a format string "{0} {1}" would format two parameters | |
| 97 | + * as strings. | |
| 98 | + * <p> | |
| 99 | + * When mapping ResourceBundle names to ResourceBundles, the Logger | |
| 100 | + * will first try to use the Thread's ContextClassLoader. If that | |
| 101 | + * is null it will try the SystemClassLoader instead. As a temporary | |
| 102 | + * transition feature in the initial implementation, if the Logger is | |
| 103 | + * unable to locate a ResourceBundle from the ContextClassLoader or | |
| 104 | + * SystemClassLoader the Logger will also search up the class stack | |
| 105 | + * and use successive calling ClassLoaders to try to locate a ResourceBundle. | |
| 106 | + * (This call stack search is to allow containers to transition to | |
| 107 | + * using ContextClassLoaders and is likely to be removed in future | |
| 108 | + * versions.) | |
| 109 | + * <p> | |
| 110 | + * Formatting (including localization) is the responsibility of | |
| 111 | + * the output Handler, which will typically call a Formatter. | |
| 112 | + * <p> | |
| 113 | + * Note that formatting need not occur synchronously. It may be delayed | |
| 114 | + * until a LogRecord is actually written to an external sink. | |
| 115 | + * <p> | |
| 116 | + * The logging methods are grouped in five main categories: | |
| 117 | + * <ul> | |
| 118 | + * <li><p> | |
| 119 | + * There are a set of "log" methods that take a log level, a message | |
| 120 | + * string, and optionally some parameters to the message string. | |
| 121 | + * <li><p> | |
| 122 | + * There are a set of "logp" methods (for "log precise") that are | |
| 123 | + * like the "log" methods, but also take an explicit source class name | |
| 124 | + * and method name. | |
| 125 | + * <li><p> | |
| 126 | + * There are a set of "logrb" method (for "log with resource bundle") | |
| 127 | + * that are like the "logp" method, but also take an explicit resource | |
| 128 | + * bundle name for use in localizing the log message. | |
| 129 | + * <li><p> | |
| 130 | + * There are convenience methods for tracing method entries (the | |
| 131 | + * "entering" methods), method returns (the "exiting" methods) and | |
| 132 | + * throwing exceptions (the "throwing" methods). | |
| 133 | + * <li><p> | |
| 134 | + * Finally, there are a set of convenience methods for use in the | |
| 135 | + * very simplest cases, when a developer simply wants to log a | |
| 136 | + * simple string at a given log level. These methods are named | |
| 137 | + * after the standard Level names ("severe", "warning", "info", etc.) | |
| 138 | + * and take a single argument, a message string. | |
| 139 | + * </ul> | |
| 140 | + * <p> | |
| 141 | + * For the methods that do not take an explicit source name and | |
| 142 | + * method name, the Logging framework will make a "best effort" | |
| 143 | + * to determine which class and method called into the logging method. | |
| 144 | + * However, it is important to realize that this automatically inferred | |
| 145 | + * information may only be approximate (or may even be quite wrong!). | |
| 146 | + * Virtual machines are allowed to do extensive optimizations when | |
| 147 | + * JITing and may entirely remove stack frames, making it impossible | |
| 148 | + * to reliably locate the calling class and method. | |
| 149 | + * <P> | |
| 150 | + * All methods on Logger are multi-thread safe. | |
| 151 | + * <p> | |
| 152 | + * <b>Subclassing Information:</b> Note that a LogManager class may | |
| 153 | + * provide its own implementation of named Loggers for any point in | |
| 154 | + * the namespace. Therefore, any subclasses of Logger (unless they | |
| 155 | + * are implemented in conjunction with a new LogManager class) should | |
| 156 | + * take care to obtain a Logger instance from the LogManager class and | |
| 157 | + * should delegate operations such as "isLoggable" and "log(LogRecord)" | |
| 158 | + * to that instance. Note that in order to intercept all logging | |
| 159 | + * output, subclasses need only override the log(LogRecord) method. | |
| 160 | + * All the other logging methods are implemented as calls on this | |
| 161 | + * log(LogRecord) method. | |
| 162 | + * | |
| 163 | + * @since 1.4 | |
