Detailed Description

Performance counters for render modes.

Render modes can be instrumented with various counters to measure performance. These counters are organized in a hierarchical fashion. This interface supports the discovery of existing counters and their hierarchy, as well as the retrieval of counter values.

Each counter is identified by a string key. The key describes the path in the hierarchy. A path consists of names delimited by a dot, e.g., "textures.nb_objs". The empty string represents the root of the hierarchy, a delimiter is not necessary here, i.e., "textures" would be a valid key just below the root, not ".textures".

Note that the counter hierarchy is not required to be stable.

Member Function Documentation

^◆ get_description()

virtual const char * mi::neuraylib::IRender_counters::get_description ( const char * key ) const

pure virtual

Returns the description for a given key.

Parameters

key	The key for which the description shall be returned.

Returns: A description of the meaning of the key key.

^◆ get_subkey()

virtual const char * mi::neuraylib::IRender_counters::get_subkey	(	const char *	key,
		Size	index
	)		const

pure virtual

Returns a subkey for a given key.

Parameters

key	The key for which a particular subkey shall be returned. The empty string can be used to retrieve the top-level subkeys.
index	The index of the subkey in question. The valid index range is from 0 to get_subkeys_size() - 1.

Returns: The requested subkey, or NULL in case of failure. Note that the returned value is actually the last path component of the subkey, not the complete subkey.

^◆ get_subkeys_size()

virtual Size mi::neuraylib::IRender_counters::get_subkeys_size ( const char * key ) const

pure virtual

Returns the number of subkeys of a key.

Parameters

key	The key for which the number of subkeys shall be returned. The empty string can be used to retrieve the top-level subkeys.

Returns: The number of subkeys this key has.

^◆ get_unit()

virtual const char * mi::neuraylib::IRender_counters::get_unit ( const char * key ) const

pure virtual

Returns the unit of the value associated with a given key.

Parameters

key	The key for which the unit of the associated value shall be returned.

Returns: The unit of the value associated with key, or NULL if there is no unit for this key.

^◆ get_value()

virtual bool mi::neuraylib::IRender_counters::get_value	(	const char *	key,
		Float64 &	value
	)		const

pure virtual

Returns the value associated with a given key.

Parameters

key	The key for which the associated value shall be returned.
value	The value associated with `key`.

Returns: true in case of success, false in case of failure (e.g. the key is invalid).
