## Detailed Description

This abstract class defines an interface which is called back during resource group loading to indicate the progress of the load.

Remarks:
  Resource group loading is in 2 phases - creating resources from declarations (which includes parsing scripts), and loading resources. Note that you don't necessarily have to have both; it is quite possible to just parse all the scripts for a group (see ResourceGroupManager::initialiseResourceGroup, but not to load the resource group. The sequence of events is (* signifies a repeating item):
  - resourceGroupScriptingStarted
  - scriptParseStarted (*)
  - scriptParseEnded (*)
  - resourceGroupScriptingEnded
  - resourceGroupLoadStarted
  - resourceLoadStarted (*)
  - resourceLoadEnded (*)
  - worldGeometryStageStarted (*)
  - worldGeometryStageEnded (*)
  - resourceGroupLoadEnded
  - resourceGroupPrepareStarted
  - resourcePrepareStarted (*)
  - resourcePrepareEnded (*)
  - resourceGroupPrepareEnded

Note:
  If OGRE_THREAD_SUPPORT is 1, this class is thread-safe.

## Member Function Documentation

virtual void Ogre::ResourceGroupListener::resourceGroupScriptingStarted | ( | const String & | groupName,
|  | size_t | scriptCount |
| ) |  |  | `[pure virtual]`

This event is fired when a resource group begins parsing scripts.

Note:
  Remember that if you are loading resources through ResourceBackgroundQueue, these callbacks will occur in the background thread, so you should not perform any thread-unsafe actions in this callback if that's the case (check the group name / script name).

Parameters:

  | groupName | The name of the group
  | scriptCount | The number of scripts which will be parsed

virtual void Ogre::ResourceGroupListener::scriptParseStarted | ( | const String & | scriptName,
|  | bool & | skipThisScript |
| ) |  |  | `[pure virtual]`

This event is fired when a script is about to be parsed.

Parameters:

  | scriptName | Name of the to be parsed
  | skipThisScript | A boolean passed by reference which is by default set to false. If the event sets this to true, the script will be skipped and not parsed. Note that in this case the scriptParseEnded event will not be raised for this script.

virtual void Ogre::ResourceGroupListener::scriptParseEnded | ( | const String & | scriptName,
|  | bool | skipped |
| ) |  |  | `[pure virtual]`

This event is fired when the script has been fully parsed.

virtual void Ogre::ResourceGroupListener::resourceGroupScriptingEnded | ( | const String & | groupName | ) | `[pure virtual]`

This event is fired when a resource group finished parsing scripts.

virtual void Ogre::ResourceGroupListener::resourceGroupPrepareStarted | ( | const String & | groupName,
|  | size_t | resourceCount |
| ) |  |  | `[virtual]`

This event is fired when a resource group begins preparing.

Parameters:

  | groupName | The name of the group being prepared
  | resourceCount | The number of resources which will be prepared, including a number of stages required to prepare any linked world geometry

Definition at line 115 of file OgreResourceGroupManager.h.

virtual void Ogre::ResourceGroupListener::resourcePrepareStarted | ( | const ResourcePtr & | resource | ) | `[virtual]`

This event is fired when a declared resource is about to be prepared.

Parameters:

  | resource | Weak reference to the resource prepared.

Definition at line 119 of file OgreResourceGroupManager.h.

virtual void Ogre::ResourceGroupListener::resourcePrepareEnded | ( | void |  | ) | `[virtual]`

This event is fired when the resource has been prepared.

Definition at line 122 of file OgreResourceGroupManager.h.

virtual void Ogre::ResourceGroupListener::worldGeometryPrepareStageStarted | ( | const String & | description | ) | `[virtual]`

This event is fired when a stage of preparing linked world geometry is about to start.

The number of stages required will have been included in the resourceCount passed in resourceGroupLoadStarted.

Parameters:

  | description | Text description of what was just prepared

Definition at line 128 of file OgreResourceGroupManager.h.

virtual void Ogre::ResourceGroupListener::worldGeometryPrepareStageEnded | ( | void |  | ) | `[virtual]`

This event is fired when a stage of preparing linked world geometry has been completed.

The number of stages required will have been included in the resourceCount passed in resourceGroupLoadStarted.

Parameters:

  | description | Text description of what was just prepared

Definition at line 134 of file OgreResourceGroupManager.h.

virtual void Ogre::ResourceGroupListener::resourceGroupPrepareEnded | ( | const String & | groupName | ) | `[virtual]`

This event is fired when a resource group finished preparing.

Definition at line 136 of file OgreResourceGroupManager.h.

virtual void Ogre::ResourceGroupListener::resourceGroupLoadStarted | ( | const String & | groupName,
|  | size_t | resourceCount |
| ) |  |  | `[pure virtual]`

This event is fired when a resource group begins loading.

Parameters:

  | groupName | The name of the group being loaded
  | resourceCount | The number of resources which will be loaded, including a number of stages required to load any linked world geometry

virtual void Ogre::ResourceGroupListener::resourceLoadStarted | ( | const ResourcePtr & | resource | ) | `[pure virtual]`

This event is fired when a declared resource is about to be loaded.

Parameters:

  | resource | Weak reference to the resource loaded.

virtual void Ogre::ResourceGroupListener::resourceLoadEnded | ( | void |  | ) | `[pure virtual]`

This event is fired when the resource has been loaded.

virtual void Ogre::ResourceGroupListener::worldGeometryStageStarted | ( | const String & | description | ) | `[pure virtual]`

This event is fired when a stage of loading linked world geometry is about to start.

The number of stages required will have been included in the resourceCount passed in resourceGroupLoadStarted.

Parameters:

  | description | Text description of what was just loaded

virtual void Ogre::ResourceGroupListener::worldGeometryStageEnded | ( | void |  | ) | `[pure virtual]`

This event is fired when a stage of loading linked world geometry has been completed.

The number of stages required will have been included in the resourceCount passed in resourceGroupLoadStarted.

Parameters:

  | description | Text description of what was just loaded

virtual void Ogre::ResourceGroupListener::resourceGroupLoadEnded | ( | const String & | groupName | ) | `[pure virtual]`

This event is fired when a resource group finished loading.
