Parameters

value	Update value.
index	Index of the element to update.

Exceptions

std::invalid_argument Shader variable type mismatch.

Reimplemented from gl::shader_variable.

void gl::gl_shader_int::update	(	std::span< const int >	values,
		std::size_t	index = `0`
	)		const

overridevirtual

Updates the values of one or more elements in an array variable.

Parameters

values	Contiguous sequence of update values.
index	Index of the first element to update.
