Detailed Description

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
