A pointer-semantics object representing a single texture.

Documentation

A pointer-semantics object representing a single texture. Must be explicitly allocated and returned.

This is a very low-level class, containing simply the GLuint texture object identifier.

Inheritance:

Id

Public Methods

	Id () Create a new texture id object.
	~Id () Destroy a texture id - note that the OpenGL texture itself is NOT deallocated by this.
void	alloc () Change this texture id to a newly allocated OpenGL texture id
void	free () Free the OpenGL texture object referred to by this object.
void	bind (GLenum target = GL_TEXTURE_2D) const Cause OpenGL to bind this texture
bool	operator== (const Id &t) const Compare two Ids -- usual semantics
bool	operator!= (const Id &t) const Compare two Ids -- usual semantics
bool	isGood () True if this id is allocated.
GLuint	getTexId () Break encapsulation for JNI ;)

Id()

Create a new texture id object. Newly created objects are set to "null".

~Id()

Destroy a texture id - note that the OpenGL texture itself is NOT deallocated by this. The texture must be explicitly freed by calling free().

void alloc()

Change this texture id to a newly allocated OpenGL texture id

void free()

Free the OpenGL texture object referred to by this object. Note that the Id objects follow pointer semantics so using a copy of the Id after freeing another copy will do undefined (probably bad) stuff.

void bind(GLenum target = GL_TEXTURE_2D) const

Cause OpenGL to bind this texture

bool operator==(const Id &t) const

Compare two Ids -- usual semantics

bool operator!=(const Id &t) const

Compare two Ids -- usual semantics

bool isGood()

True if this id is allocated. This test only checks whether the Id is null or not.

GLuint getTexId()

Break encapsulation for JNI ;)

This class has no child classes.
