[Android.Runtime.Register("log", "(Ljava/util/logging/Level;Ljava/lang/String;[Ljava/lang/Object;)V", "GetLog_Ljava_util_logging_Level_Ljava_lang_String_arrayLjava_lang_Object_Handler")]
public virtual void Log (Java.Util.Logging.Level level, string? msg, Java.Lang.Object[]? params);

[<Android.Runtime.Register("log", "(Ljava/util/logging/Level;Ljava/lang/String;[Ljava/lang/Object;)V", "GetLog_Ljava_util_logging_Level_Ljava_lang_String_arrayLjava_lang_Object_Handler")>]
abstract member Log : Java.Util.Logging.Level * string * Java.Lang.Object[] -> unit
override this.Log : Java.Util.Logging.Level * string * Java.Lang.Object[] -> unit

Parameters

level: Level

One of the message level identifiers, e.g., SEVERE

msg: String

The string message (or a key in the message catalog)

params: Object[]

array of parameters to the message

Attributes: RegisterAttribute

Remarks

Log a message, with an array of object arguments.

If the logger is currently enabled for the given message level then a corresponding LogRecord is created and forwarded to all the registered output Handler objects.

Applies to

Log(Level, String, Throwable)

Log a message, with associated Throwable information.

[Android.Runtime.Register("log", "(Ljava/util/logging/Level;Ljava/lang/String;Ljava/lang/Throwable;)V", "GetLog_Ljava_util_logging_Level_Ljava_lang_String_Ljava_lang_Throwable_Handler")]
public virtual void Log (Java.Util.Logging.Level level, string? msg, Java.Lang.Throwable? thrown);

[<Android.Runtime.Register("log", "(Ljava/util/logging/Level;Ljava/lang/String;Ljava/lang/Throwable;)V", "GetLog_Ljava_util_logging_Level_Ljava_lang_String_Ljava_lang_Throwable_Handler")>]
abstract member Log : Java.Util.Logging.Level * string * Java.Lang.Throwable -> unit
override this.Log : Java.Util.Logging.Level * string * Java.Lang.Throwable -> unit

Parameters

level: Level

One of the message level identifiers, e.g., SEVERE

msg: String

The string message (or a key in the message catalog)

thrown: Throwable

Throwable associated with log message.

Attributes: RegisterAttribute

Remarks

Log a message, with associated Throwable information.

If the logger is currently enabled for the given message level then the given arguments are stored in a LogRecord which is forwarded to all registered output handlers.

Note that the thrown argument is stored in the LogRecord thrown property, rather than the LogRecord parameters property. Thus it is processed specially by output Formatters and is not treated as a formatting parameter to the LogRecord message property.

Parameters

record: LogRecord

the LogRecord to be published

Attributes: RegisterAttribute

Applies to

Log(Level, Throwable, ISupplier)

Log a lazily constructed message, with associated Throwable information.

[Android.Runtime.Register("log", "(Ljava/util/logging/Level;Ljava/lang/Throwable;Ljava/util/function/Supplier;)V", "GetLog_Ljava_util_logging_Level_Ljava_lang_Throwable_Ljava_util_function_Supplier_Handler", ApiSince=26)]
public virtual void Log (Java.Util.Logging.Level level, Java.Lang.Throwable? thrown, Java.Util.Functions.ISupplier msgSupplier);

[<Android.Runtime.Register("log", "(Ljava/util/logging/Level;Ljava/lang/Throwable;Ljava/util/function/Supplier;)V", "GetLog_Ljava_util_logging_Level_Ljava_lang_Throwable_Ljava_util_function_Supplier_Handler", ApiSince=26)>]

override this.Log : Java.Util.Logging.Level * Java.Lang.Throwable * Java.Util.Functions.ISupplier -> unit

Parameters

level: Level

One of the message level identifiers, e.g., SEVERE

thrown: Throwable

Throwable associated with log message.

msgSupplier: ISupplier

A function, which when called, produces the desired log message

Attributes: RegisterAttribute

Remarks

Log a lazily constructed message, with associated Throwable information.

If the logger is currently enabled for the given message level then the message is constructed by invoking the provided supplier function. The message and the given Throwable are then stored in a LogRecord which is forwarded to all registered output handlers.
