Uniform blocks

#include <oglplus/uniform_block.hpp>

Basic block location operations

template <>
class ProgVarLocOps<tag::UniformBlock>
{
public:
	static GLint GetLocation(
		ProgramName program,
		StrCRef identifier,
		bool active_only
	); 
};

Finds the location of the uniform block specified by identifier in a program. If active_only is true then throws ProgVarError if no such uniform block exists or if it is not active. See glGetUniformBlockIndex.

Common uniform block operations

template <>
class ProgVarCommonOps<tag::UniformBlock>
 : public ProgVarLoc<tag::UniformBlock>
{
public:
	static GLuint MaxIn(ShaderType shader_type); 

	Boolean ReferencedBy(ShaderType shader_type) const; 

	GLuint DataSize(void) const; 

	void Binding(UniformBufferBindingPoint binding); 
};

	Returns the maximum number of uniform blocks for a `shader_type`.
	Returns `true` if this uniform block is referenced by a `shader_type`. See `glGetActiveUniformBlock`.
	Returns the size of the uniform block. See `glGetActiveUniformBlock`, `GL_UNIFORM_BLOCK_DATA_SIZE`.
	Sets up the uniform block binding. See `glUniformBlockBinding`.

Definition

template <typename T>
using Uniform = ProgVar<
	tag::ImplicitSel,
	tag::UniformBlock,
	tag::NoTypecheck,
	void
>;

UniformBlock indirectly inherits from ProgVarLocOps and ProgVarCommonOps.
