Public Member Functions

 Technique (Context *context)
 Construct.
 
 ~Technique ()
 Destruct.
 
virtual bool BeginLoad (Deserializer &source)
 Load resource from stream. May be called from a worker thread. Return true if successful.
 
void SetIsDesktop (bool enable)
 Set whether requires desktop level hardware.
 
PassCreatePass (const String &passName)
 Create a new pass.
 
void RemovePass (const String &passName)
 Remove a pass.
 
void ReleaseShaders ()

 Return whether technique is supported by the current hardware.
 
bool HasPass (unsigned passIndex) const
 Return whether has a pass.
 
bool HasPass (const String &passName) const
 Return whether has a pass by name. This overload should not be called in time-critical rendering loops; use a pre-acquired pass index instead.
 
PassGetPass (unsigned passIndex) const
 Return a pass, or null if not found.
 
PassGetPass (const String &passName) const
 Return a pass by name, or null if not found. This overload should not be called in time-critical rendering loops; use a pre-acquired pass index instead.
 
PassGetSupportedPass (unsigned passIndex) const
 Return a pass that is supported for rendering, or null if not found.
 
PassGetSupportedPass (const String &passName) const
 Return a supported pass by name. This overload should not be called in time-critical rendering loops; use a pre-acquired pass index instead.
 
unsigned GetNumPasses () const
 Return number of passes.
 
Vector< StringGetPassNames () const
 Return all pass names.
 
PODVector< Pass * > GetPasses () const
 Return all passes.
 
- Public Member Functions inherited from Urho3D::Resource
 Resource (Context *context)
 Construct.
 
bool Load (Deserializer &source)
 Load resource synchronously. Call both BeginLoad() & EndLoad() and return true if both succeeded.
 
virtual bool EndLoad ()
 Finish resource loading. Always called from the main thread. Return true if successful.
 
virtual bool Save (Serializer &dest) const
 Save resource. Return true if successful.
 
void SetName (const String &name)
 Set name.
 
void SetMemoryUse (unsigned size)
 Set memory use in bytes, possibly approximate.
 
void ResetUseTimer ()
 Reset last used timer.
 
void SetAsyncLoadState (AsyncLoadState newState)
 Set the asynchronous loading state. Called by ResourceCache. Resources in the middle of asynchronous loading are not normally returned to user.
 
const StringGetName () const
 Return name.
 
StringHash GetNameHash () const
 Return name hash.
 
unsigned GetMemoryUse () const
 Return memory use in bytes, possibly approximate.
 
unsigned GetUseTimer ()
 Return time since last use in milliseconds. If referred to elsewhere than in the resource cache, returns always zero.
 
AsyncLoadState GetAsyncLoadState () const
 Return the asynchronous loading state.

 Send event to all subscribers.
 
void SendEvent (StringHash eventType, VariantMap &eventData)
 Send event with parameters to all subscribers. More...
