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.
|
pure virtual |
Returns the description for a given key.
key | The key for which the description shall be returned. |
key
.
|
pure virtual |
Returns a subkey for a given key.
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. |
nullptr
in case of failure. Note that the returned value is actually the last path component of the subkey, not the complete subkey.
|
pure virtual |
Returns the number of subkeys of a key.
key | The key for which the number of subkeys shall be returned. The empty string can be used to retrieve the top-level subkeys. |
|
pure virtual |
Returns the unit of the value associated with a given key.
key | The key for which the unit of the associated value shall be returned. |
key
, or nullptr
if there is no unit for this key.
|
pure virtual |
Returns the value associated with a given key.
key | The key for which the associated value shall be returned. |
value | The value associated with key . |
true
in case of success, false
in case of failure (e.g. the key is invalid).
