ShaderManager::ShaderManager

(

)

[private]

The constructor.

Initializes the shader manager.

ShaderManager::ShaderManager

(

const ShaderManager &

source

)

[private]

The copy constructor.

Should not be called.

ShaderManager::~ShaderManager

(

)

[private]

The destructor.

Destroyes the shader manager and frees all memory occupied by shaders. Should only be called for program termination.

Member Function Documentation

char * ShaderManager::loadSource

(

const char *

filename

)

[private]

reads a textfile

Reads a textfile from disk

Parameters:

filename

The file to be read.

void ShaderManager::loadShader

(

struct shaderEntry *

entry

)

[private]

Loads a shader from file to OpenGL.

Creates a shader from file

void ShaderManager::reload

(

)

[private]

Reloads textures after resize.

Reloads all used shader from disk to graphics card memory

ShaderManager * ShaderManager::getInstance

(

)

[static]

The singleton getter.

The only way to access the manager

void ShaderManager::registerShader

(

const string &

filename

)

Registers a shader for use in the Shader Manager.

Adds a shader if not already present, otherwise increases its count.

Parameters:

filename

Must be a valid filename (without suffix) otherwise we got a problem

void ShaderManager::unregisterShader

(

const string &

filename

)

Unregisters a shader.

Removes a shader from memory if no longer used by other objects, otherwise decreases its count.

Parameters:

filename

Must be a filename (without suffix) already registered otherwise the call will have no effect.

void ShaderManager::unregisterShader

(

struct shaderEntry *const

data

)

Unregisters a shader.

void ShaderManager::processEvent

(

SDL_Event &

event

)

[virtual]

A method to deal with SDL_Event.

Implements EventListener.

struct shaderEntry * ShaderManager::getEntry

(

const string &

filename

)

[read]

string ShaderManager::toString

(

)

const [virtual]

Returns a textual representation.

Returns:

a string descriping the run-time object

Implements EventListener.

string ShaderManager::className

(

)

const [virtual]

Returns the class name of the object.

Returns:

a string with the name of the object's class

Implements EventListener.

enum classId ShaderManager::classId

(

)

const [virtual]

Returns the class id of the object.

Returns:

an id of the object's class

Implements EventListener.
