The ILogger interface class supports logging of messages.
Plugins based on mi::base::Plugin are provided with a logger, such that plugins can be written to use the same message log as the host application.
Different APIs allow to register your own implementation of a logger to override their internal implementation. Note that in such case the object implementing this interface shall not be created on the stack, since this might lead to premature destruction of such instances while still being in use by the API.
The following message categories are used in some APIs. There might be other, undocumented categories.
category | purpose |
---|---|
"DATABASE" | database |
"DISK" | raw disk I/O, swapping |
"GEOMETRY" | geometry processing, e.g., tessellation |
"IMAGE" | texture processing, image and video plugins |
"IO" | scene data import and export |
"MAIN" | reserved for the application itself |
"MISC" | other |
"MEMORY" | memory management |
"NETWORK" | networking |
"PLUGIN" | plugins (unless other categories fit better) |
"RENDER" | rendering |
|
pure virtual |
Emits a message to the application's log.
The application can decide to output the message to any channel or to drop it.
This function can be called at any time from any thread, including concurrent calls from several threads at the same time.
level | The log level which specifies the severity of the message. |
module_category | The module and the category which specify the origin and the functional area of this message. The format of string parameter is "module:category". Both names are optional. The module name must not contain any colons. See above for valid category names. |
message | The log message. |
|
inline |
Emits a message to the application's log.
The application can decide to output the message to any channel or to drop it.
This function can be called at any time from any thread, including concurrent calls from several threads at the same time.
level | The log level which specifies the severity of the message. |
module_category | The module and the category which specify the origin and the functional area of this message. The format of string parameter is "module:category". Both names are optional. The module name must not contain any colons. See above for valid category names. |
message | The log message using printf()-like format specifiers, followed by matching arguments. The formatted message is limited to 1024 characters. |
