Ogre::ShaderParams Class Reference

The purpose of this class is to contain a set of both auto and manual parameters that may apply to multiple shaders; without having the shader to be created first (the drawback of GpuProgramParameters). More...

Detailed Description

The purpose of this class is to contain a set of both auto and manual parameters that may apply to multiple shaders; without having the shader to be created first (the drawback of GpuProgramParameters).

Useful when loading an Hlms material via JSON (e.g. a Compute Job) which may generate multiple shaders depending on the property settings.

Parameters are kept unsorted in mParams

findParameter()

Param* Ogre::ShaderParams::findParameter

(

const String &

name

)

Finds a parameter.

Returns null if not found. This operation is O(N) as it makes a linear search. You can cache the return pointer (as long as the iterators from mParams aren't invalidated)

removeParameterNoThrow()

bool Ogre::ShaderParams::removeParameterNoThrow

(

const String &

name

)

Removes a parameter if it matches the name.

Remarks

You shouldn't have multiple parameters with the same name. But if you do, then we will only remove the first match. You can call this function again until all matches are removed (beware of O(N^2) behavior though!)

Calling this function may alter the order of entries in mParams!

Parameters

name

Returns

Returns true if we removed a parameter with such name. Returns false if said parameter couldn't be found.

setDirty()

void Ogre::ShaderParams::setDirty ( void  )

inline

Call this whenever you've updated a parameter in mParams.

updateParameters()

void Ogre::ShaderParams::updateParameters	(	GpuProgramParametersSharedPtr	params,
		bool	bForce
	)
