GLSLShader Class Reference

Detailed Description

GLSL shader class.

This class provides basic functionality for compiling GLSL shaders either from a given source string or a given file. It only stores the shader ID and it can be safely deleted after the shader is used for building (linking) a GLSL program.

Public Member Functions
	GLSLShader ()
	Constructor.
virtual	~GLSLShader ()
	Destructor that deletes the shader.
General Methods
void	Delete ()
	Deletes the shader.
GLuint	GetID () const
	Returns the shader ID.
bool	IsNull () const
	Returns true if the OpenGL shader object is not generated, i.e. the shader id is invalid.
Compilation Methods
bool	CompileFile (char const *filename, GLenum shaderType, std::ostream *outStream=&std::cout)
	Compiles the shader using the given file. If the shader was previously compiled, it is deleted.
bool	CompileFile (char const *filename, GLenum shaderType, char const *prependSource, std::ostream *outStream=&std::cout)
	Compiles the shader using the given file. If the shader was previously compiled, it is deleted. The prependSource string is added to the beginning of the shader code, so it must begin with the "#version" statement.
bool	CompileFile (char const *filename, GLenum shaderType, int prependSourceCount, char const **prependSources, std::ostream *outStream=&std::cout)
	Compiles the shader using the given file. If the shader was previously compiled, it is deleted. The prependSources strings are added to the beginning of the shader code, so the first string must begin with "#version" statement.
bool	Compile (char const *shaderSourceCode, GLenum shaderType, std::ostream *outStream=&std::cout)
	Compiles the shader using the given source code. If the shader was previously compiled, it is deleted.
bool	Compile (char const *shaderSourceCode, GLenum shaderType, char const *prependSource, std::ostream *outStream=&std::cout)
	Compiles the shader using the given source code. If the shader was previously compiled, it is deleted. The prependSource string is added to the beginning of the shader code, so it must begin with the "#version" statement.
bool	Compile (char const *shaderSourceCode, GLenum shaderType, int prependSourceCount, char const **prependSources, std::ostream *outStream=&std::cout)
	Compiles the shader using the given source code. If the shader was previously compiled, it is deleted. The prependSources strings are added to the beginning of the shader code, so the first string must begin with "#version" statement.
