## Member Function Documentation

virtual const String& Ogre::ParticleSystemRenderer::getType | ( | void |  | ) | const`[pure virtual]`

Gets the type of this renderer - must be implemented by subclasses.

Implemented in Ogre::BillboardParticleRenderer.

Sets the material this renderer must use; called by ParticleSystem.

Tells the renderer that the particle quota has changed.

Implemented in Ogre::BillboardParticleRenderer.

virtual void Ogre::ParticleSystemRenderer::_notifyDefaultDimensions | ( | Real | width,
|  | Real | height |
| ) |  |  | `[pure virtual]`

Tells the renderer that the particle default size has changed.

Implemented in Ogre::BillboardParticleRenderer.

virtual void Ogre::ParticleSystemRenderer::_notifyParticleEmitted | ( | Particle * | particle | ) | `[virtual]`

Optional callback notified when particle emitted.

Definition at line 77 of file OgreParticleSystemRenderer.h.

virtual void Ogre::ParticleSystemRenderer::_notifyParticleExpired | ( | Particle * | particle | ) | `[virtual]`

Optional callback notified when particle expired.

Definition at line 79 of file OgreParticleSystemRenderer.h.

virtual void Ogre::ParticleSystemRenderer::_notifyParticleMoved | ( | std::list< Particle * > & | currentParticles | ) | `[virtual]`

virtual void Ogre::ParticleSystemRenderer::_notifyParticleCleared | ( | std::list< Particle * > & | currentParticles | ) | `[virtual]`

Optional callback notified when particles cleared.

Definition at line 83 of file OgreParticleSystemRenderer.h.

virtual ParticleVisualData* Ogre::ParticleSystemRenderer::_createVisualData | ( | void |  | ) | `[virtual]`

Create a new ParticleVisualData instance for attachment to a particle.

Remarks:
  If this renderer needs additional data in each particle, then this should be held in an instance of a subclass of ParticleVisualData, and this method should be overridden to return a new instance of it. The default behaviour is to return null.

Definition at line 91 of file OgreParticleSystemRenderer.h.

virtual void Ogre::ParticleSystemRenderer::_destroyVisualData | ( | ParticleVisualData * | vis | ) | `[virtual]`

Destroy a ParticleVisualData instance.

Remarks:
  If this renderer needs additional data in each particle, then this should be held in an instance of a subclass of ParticleVisualData, and this method should be overridden to destroy an instance of it. The default behaviour is to do nothing.

Definition at line 99 of file OgreParticleSystemRenderer.h.

virtual void Ogre::ParticleSystemRenderer::setRenderQueueGroup | ( | uint8 | queueID | ) | `[pure virtual]`

Sets which render queue group this renderer should target with it's output.

Implemented in Ogre::BillboardParticleRenderer.

virtual void Ogre::ParticleSystemRenderer::setKeepParticlesInLocalSpace | ( | bool | keepLocal | ) | `[pure virtual]`

Setting carried over from ParticleSystem.

Implemented in Ogre::BillboardParticleRenderer.

virtual SortMode Ogre::ParticleSystemRenderer::_getSortMode | ( | void |  | ) | const`[pure virtual]`

Gets the desired particles sort mode of this renderer.

Implemented in Ogre::BillboardParticleRenderer.

bool Ogre::StringInterface::createParamDictionary | ( | const String & | className | ) | `[protected, inherited]`

Internal method for creating a parameter dictionary for the class, if it does not already exist.

Remarks:
  This method will check to see if a parameter dictionary exist for this class yet, and if not will create one. NB you must supply the name of the class (RTTI is not used or performance).

Parameters:

  | className | the name of the class using the dictionary

Returns:
  true if a new dictionary was created, false if it was already there

Definition at line 176 of file OgreStringInterface.h.

ParamDictionary* Ogre::StringInterface::getParamDictionary | ( | void |  | ) | `[inherited]`

Retrieves the parameter dictionary for this class.

Remarks:
  Only valid to call this after createParamDictionary.

Returns:
  Pointer to ParamDictionary shared by all instances of this class which you can add parameters to, retrieve parameters etc.

Definition at line 200 of file OgreStringInterface.h.

const ParamDictionary* Ogre::StringInterface::getParamDictionary | ( | void |  | ) | const`[inherited]`

Definition at line 213 of file OgreStringInterface.h.

const ParameterList& Ogre::StringInterface::getParameters | ( | void |  | ) | const`[inherited]`

Retrieves a list of parameters valid for this object.

Returns:
  A reference to a static list of ParameterDef objects.

virtual bool Ogre::StringInterface::setParameter | ( | const String & | name,
|  | const String & | value |
| ) |  |  | `[virtual, inherited]`

Generic parameter setting method.

Remarks:
  Call this method with the name of a parameter and a string version of the value to set. The implementor will convert the string to a native type internally. If in doubt, check the parameter definition in the list returned from StringInterface::getParameters.

Parameters:

  | name | The name of the parameter to set
  | value | String value. Must be in the right format for the type specified in the parameter definition. See the StringConverter class for more information.

Returns:
  true if set was successful, false otherwise (NB no exceptions thrown - tolerant method)

Referenced by Ogre::StringInterface::copyParametersTo().

virtual void Ogre::StringInterface::setParameterList | ( | const NameValuePairList & | paramList | ) | `[virtual, inherited]`

Generic multiple parameter setting method.

Remarks:
  Call this method with a list of name / value pairs to set. The implementor will convert the string to a native type internally. If in doubt, check the parameter definition in the list returned from StringInterface::getParameters.

Parameters:

  | paramList | Name/value pair list

virtual String Ogre::StringInterface::getParameter | ( | const String & | name | ) | const`[virtual, inherited]`

Generic parameter retrieval method.

Remarks:
  Call this method with the name of a parameter to retrieve a string-format value of the parameter in question. If in doubt, check the parameter definition in the list returned from getParameters for the type of this parameter. If you like you can use StringConverter to convert this string back into a native type.

Parameters:

  | name | The name of the parameter to get

Returns:
  String value of parameter, blank if not found

Definition at line 269 of file OgreStringInterface.h.

References Ogre::ParamCommand::doGet(), and Ogre::ParamDictionary::getParamCommand().

virtual void Ogre::StringInterface::copyParametersTo | ( | StringInterface * | dest | ) | const`[virtual, inherited]`

Method for copying this object's parameters to another object.

Remarks:
  This method takes the values of all the object's parameters and tries to set the same values on the destination object. This provides a completely type independent way to copy parameters to other objects. Note that because of the String manipulation involved, this should not be regarded as an efficient process and should be saved for times outside of the rendering loop.

  Any unrecognised parameters will be ignored as with setParameter method.

Parameters:

  | dest | Pointer to object to have it's parameters set the same as this object.

Definition at line 300 of file OgreStringInterface.h.

References Ogre::ParamDictionary::mParamDefs, and Ogre::StringInterface::setParameter().

static void Ogre::StringInterface::cleanupDictionary | ( |  | ) | `[static, inherited]`

Cleans up the static 'msDictionary' required to reset Ogre, otherwise the containers are left with invalid pointers, which will lead to a crash as soon as one of the ResourceManager implementers (e.g.

MaterialManager) initializes.
